IACR Transactions on Cryptographic Hardware and Embedded Systems, Universitatsbibliothek der Ruhr-Universitat Bochum, 2024, 1, 133-156, 04 Dec. 2023, Peer-reviwed, Deploying cryptography on embedded systems requires security against physical attacks. At CHES 2019, M&M was proposed as a combined countermeasure applying masking against SCAs and information-theoretic MAC tags against FAs. In this paper, we show that one of the protected AES implementations in the M&M paper is vulnerable to a zero-value SIFA2-like attack. A practical attack is demonstrated on an ASIC board. We propose two versions of the attack: the first follows the SIFA approach to inject faults in the last round, while the second one is an extension of SIFA and FTA but applied to the first round with chosen plaintext. The two versions work at the byte level, but the latter version considerably improves the efficiency of the attack. Moreover, we show that this zero-value SIFA2 attack is specific to the AES tower-field decomposed S-box design. Hence, such attacks are applicable to any implementation featuring this AES S-box architecture.Then, we propose a countermeasure that prevents these attacks. We extend M&M with a fine-grained detection-based feature capable of detecting the zero-value glitch attacks. In this effort, we also solve the problem of a combined attack on the ciphertext output check of M&M scheme by using Kronecker’s delta function. We deploy the countermeasure on FPGA and verify its security against both fault and side-channel analysis with practical experiments.

ACM Transactions on Embedded Computing Systems, Association for Computing Machinery (ACM), 22, 5, 1-17, 26 Sep. 2023, Peer-reviwed, In the Internet of Things (IoT) era, edge devices have been considerably diversified and are often designed using high-level synthesis (HLS) for improved design productivity. However, HLS tools were originally developed in a security-unaware manner, resulting in vulnerabilities to power side-channel attacks (PSCAs), which are a serious threat to IoT systems. Currently, the impact and applicability of existing methods to PSCA-resistant designs using HLS are limited. In this article, we propose an effective HLS-based design method for PSCA-resistant ciphers implemented in hardware. In particular, we focus on lightweight block ciphers composed of addition/rotation/XOR (ARX)-based permutations to study the effects of the threshold implementation (which is one of the provably secure countermeasures against PSCAs) to the behavioral descriptions of ciphers along with the changes in HLS scheduling. The results obtained using Welch’s t-test demonstrate that our proposed method can successfully improve the resistance against PSCAs for all ARX-based ciphers used as benchmarks.

International conference proceedings, English - The Limits of SEMA on Distinguishing Similar Activation Functions of Embedded Deep Neural Networks
Go Takatoi; Takeshi Sugawara; Kazuo Sakiyama; Yuko Hara-Azumi; Yang Li
Applied Sciences, MDPI AG, 12, 9, 4135-4135, 20 Apr. 2022, Artificial intelligence (AI) is progressing rapidly, and in this trend, edge AI has been researched intensively. However, much less work has been performed around the security of edge AI. Machine learning models are a mass of intellectual property, and an optimized network is very valuable. Trained machine learning models need to be black boxes as well because they may give away information about the training data to the outside world. As selecting the appropriate activation functions to enable fast training of accurate deep neural networks is an active area of research, it is important to conceal the information of the activation functions used in a neural network architecture as well. There has been research on the use of physical attacks such as the side-channel attack (SCA) in areas other than cryptography. The SCA is highly effective against edge artificial intelligence due to its property of the device computing close to the user. We studied a previously proposed method to retrieve the activation functions of a black box neural network implemented on an edge device by using simple electromagnetic analysis (SEMA) and improved the signal processing procedure for further noisy measurements. The SEMA attack identifies activation functions by directly observing distinctive electromagnetic (EM) traces that correspond to the operations in the activation function. This method requires few executions and inputs and also has little implementation dependency on the activation functions. We distinguished eight similar activation functions with EM measurements and examined the versatility and limits of this attack. In this work, the machine learning architecture is a multilayer perceptron, evaluated on an Arduino Uno.

Japanese Journal of Applied Physics, IOP Publishing, 60, SB, SBBL01-SBBL01, 10 Feb. 2021, Abstract
This paper presents an inductive impulse self-destruction circuit utilized in a sense-and-react IC-level countermeasure against physical attacks on a cryptographic processor. Triggered upon an alarm signal assertion by an integrated attack sensor, the proposed circuit instantaneously generates >10 V high-voltage impulse to permanently destruct the cryptographic processor for enhancing tamper resiliency. A compact design with only a single on-chip inductor and a transistor significantly saves the hardware overhead. The inductor accumulates large electric energy in its magnetic field and the switch transistor suddenly opens the accumulated energy to boost the impulse voltage in an inertial manner. Since the inductor is drawn over the cryptographic core by existing on-chip IC interconnections, no extra area for the inductor and no any optional IC process steps are needed. This fully standard CMOS compatible, complete circuit solution, results in no fabrication cost penalty. A prototype implemented in both discrete components and a 0.18 μm standard CMOS process successfully demonstrated the-proof-of-concept.

Japanese Journal of Applied Physics, IOP Publishing, 59, SG, SGGL02-SGGL02, 01 Apr. 2020, Peer-reviwed, Abstract
Laser fault injection (LFI) attacks on cryptographic processor ICs are a critical threat to information systems. This paper proposes an IC-level integrated countermeasure employing an information leakage sensor against an LFI attack. Distributed bulk current sensors monitor abnormal bulk current density caused by laser irradiation for LFI. Time-interleaved sensor operation and sensitivity tuning can obtain partial secret key leakage bit information with small layout area penalty. Based on the leakage information, the secret key can be securely updated to realize high-availability resilient systems. The test chip was designed and fabricated in a 0.18 μm standard CMOS, integrating a 128-bit advanced encryption standard cryptographic processor with the proposed information leakage sensor. This evaluation successfully demonstrated bulk current density and leakage bit monitoring.

Recently, authentication using near field communication is widely spread for entrance and exit control and electronic money systems. However a threat of relay attack is often pointed out. Relay attack enables an attacker to camouflage the location by developing another communication channel instead of the legitimate one. In this paper, we propose an authentication method using side-channel information, and verify the usability of it based on fundamental experiments. When a cryptographic device is working, side-channel information is leaked as a power consumption and an electromagnetic wave, which is unique information depending on secret key. Utilizing such uniqueness for communication between prover and verifier, we aim at realizing an efficient distance bounding mechanism in the RFID-based authentication system., The Institute of Electronics, Information and Communication Engineers, 03 Jul. 2014, IEICE technical report.

Secret data in embedded devices can be revealed by injecting computational faults using the fault analysis attacks. The fault analysis researches on a cryptographic implementation by far first assumed a certain fault model, and then discussed the key recovery method under some assumptions. We note that a new remote-fault injection method has emerged, which is threatening in practice. Due to its limited accessibility to cryptographic devices, the remote-fault injection, however, can only inject uncertain faults. In this surroundings, this paper gives a general strategy of the remote-fault attack on the AES block cipher with a data set of faulty ciphertexts generated by uncertain faults. Our method effectively utilizes all the information from various kinds of faults, which is more realistic than previous researches. As a result, we show that it can provide a decent success probability of key identification even when only a few intended faults are available among 32 millions fault injections.------------------------------This is a preprint of an article intended for publication Journal ofInformation Processing(JIP).

Side-channel attack recovers secret information utilizing extraneous information that leaks from cryp-tographic devices. At COSADE 2013, it has been shown that power consumption and signal delay from two AES hardware implementations, AES-COMP and AES-PPRM1, have a high correlation. In the case of AES-PPRM1, this is because Hamming weight of input values of combinatorial circuit for S-box is considered to be a good model for both side-channel information. However, it is not clear the reason why power consumption and signal delay of AES-COMP has a high correlation. In this paper, we clarify the reason by reconsidering the behavior of signal toggles in the combinatorial circuit. As a result of simulation, we show that a high correlation between power consumption and signal delay stems from the number of signal toggles of output value for S-box circuits and clarify its mechanism., The Institute of Electronics, Information and Communication Engineers, 18 Jul. 2013, 電子情報通信学会技術研究報告 = IEICE technical report : 信学技報, 113, 138, 331-338, Japanese, 0913-5685, 110009773125, AA12526316 - On Side-Channel Information Using Signal Toggles in AES Circuit

サイドチャネル攻撃は，消費電力や電磁波などのデバイスから漏洩する副次的な情報を用いて秘密情報を復元する攻撃のことである．COSADE 2013 で，AES 暗号実装の一種である AES-COMP と AES-PPRM1 において，消費電力と故障感度の相関が高いことが示された．AES-PPRM1においては，S-box の組み合せ回路に対する入力値のハミング重みが，消費電力と信号遅延量の両方のサイドチャネル情報に対する良いモデルとなっていることが理由と考えられる．しかしながら，AES-COMPに関しては，消費電力と故障感度の相関が高い理由は明らかではない．そこで本稿では，組み合せ回路の信号遷移回数を再考し，消費電力と信号遅延量との相関を詳しく調査する．シミュレーションによる結果として，AES-COMPとAES-PPRM1の両方において，消費電力と信号遅延量の高相関が，S-box 回路の出力信号の遷移回数に起因することを示し，その理由を明らかとする．Side-channel attack recovers secret information utilizing extraneous information that leaks from cryp tographic devices.

LI Yang; OHTA Kazuo; SAKIYAMA Kazuo
At CHES 2010, a novel side-channel analysis called fault sensitivity analysis (FSA) has been proposed. The essence of the FSA attack is the exploration of the relationship between the fault injection intensity and the occurrence of the faulty calculation. The originally proposed FSA attack is based on the dependency between the intermediate value and the delay timing for the combinational circuit, and can successfully recover the secret key of 128-bit AES. After that, the FSA attack has been improved from the following two directions, which have been presented at CHES 2011. 1) The break of all the AES cores for SASEBO-R by applying the FSA attack proposed at CHES 2010. 2) The enhancement of the FSA attack by additionally analyzing of the faulty ciphertext that have not been used in the original FSA attack. In this paper, the result of breaking all the AES cores on the SASEBO-R will be explained at first, and then the enhanced FSA attack using faulty ciphertext will be reported in detail especially. In 2), for the AES implementation with masking-based side-channel countermeasures, we successfully find the dependency between the unmasked S-box input and the distribution of the values for a byte of the faulty ciphertext. Based on this factor, we demonstrate how to successfully recover the difference between the secret key bytes for the Masked-AND AES implementation and the AES-Threshold on SASEBO-R., The Institute of Electronics, Information and Communication Engineers, 07 Dec. 2011, Technical report of IEICE.

YAMAMOTO Dai; SAKIYAMA Kazuo; IWAMOTO Mitsugu; OTA Kazuo; OCHIAI Takao; TAKENAKA Masahiko; ITOH Kouichi
Physical Unclonable Functions (PUFs) are expected to represent an important solution for secure ID generation and authentication etc. In general, PUFs are considered to be more secure the larger their output entropy. However, the entropy of conventional PUFs is lower than the output bit length, because some output bits are random numbers, which are regarded as unnecessary for ID generation and discarded. We propose a novel PUF structure based on a Butterfly PUF with multiple RS latches, which generates larger entropy by utilizing location information of the RS latches generating random numbers. More specifically, while conventional PUFs generate binary values (0/1), the proposed PUF generates ternary values (0/1/random) in order to increase entropy. We estimate the entropy of the proposed PUF. According to our experiment with 40 FPGAs, a Butterfly PUF with 128 RS latches can improve entropy from 116 bits to 192.7 bits, this being maximized when the frequency of each ternary value is equal. We also show the appropriate RS latch structure for satisfying this condition, and validate it through an FPGA experiment., The Institute of Electronics, Information and Communication Engineers, 07 Dec. 2011, Technical report of IEICE.

SAKAMOTO Hikaru; LI Yang; OHTA Kazuo; SAKIYAMA Kazuo
In this paper, we propose a new fault analysis attack technique using Clockwise Collision. Generally, for the combinational circuit in a synchronous design, if signal states of consecutive two cycles are same, the delay time of the second cycle is zero. Focusing on this fact, for the fault attack using setup time violation, we find out that it is difficult for an attacker to induce a fault in the operation in which Clockwise Collision occurs. As a case study, we apply this technique to Elliptic Curve Cryptography (ECC) implementation using Lopez-Dahab algorithm. Consequently, we succeeded in identifying the secret key. Our proposed attack technique is valid even if the Z coordinate of the input point is randomized. Therefore, we show that this technique is more powerful than the previous attack technique using Fault Sensitivity Analysis., The Institute of Electronics, Information and Communication Engineers, 14 Nov. 2011, IEICE technical report.

LI Qi; GOMISAWA Shigeto; IWAMOTO Mitsugu; OHTA Kazuo; SAKIYAMA Kazuo
This paper presents new differential fault analysis (DFA) on a stream cipher Trivium based on setup-time violations. Trivium is a hardware-oriented synchronous stream cipher, designed by De Canniere and Preneel in 2005. In 2008, Hojsik and Rudolf first presented differential fault analysis of Trivium and proposed two types of DFA on Trivium. Setup-time violations are common fault injection methods for hardware implementations. We show that we have succeeded in injecting faults into FPGA on SASEBO-GII in which Trivium is implemented, and in obtaining 147 out of 288 secret bits with 93 fault injections at different rounds. According to our experiments, we found it is difficult to inject 1-bit errors into random positions of the registers of Trivium at a specific round that was proposed in the previous work of Hojsik and Rudolf., The Institute of Electronics, Information and Communication Engineers, 24 Feb. 2011, IEICE technical report, 110, 444, 333-339, English, 0913-5685, 110008688483, AA11840009 - New Differential Fault Analysis on Trivium Based on Setup-Time Violations

In 2006, Iwamoto et al. introduced a visual secret sharing (VSS) schemes that allows rotation operation for shares in decryption. However, the proposed construction method is complicated and it only deals with 180-degree rotation. In this paper, based on the change of the expression of subpixels, the rotation angle for shares is extended into degrees besides 180-degree. Especially, a new VSS scheme, in which two shares can decrypt multiple secret images with appropriate rotation angles, is proposed in this paper. The proposed construction approach overcomes the shortcomings of the one proposed by Li et al.. It satisfies the information theoretical security and is simpler than preview works. Besides, it is also possible to extend the proposed schemes into n shares., The Institute of Electronics, Information and Communication Engineers, 15 May 2009, IEICE technical report, 109, 42, 29-36, English, 0913-5685, 110007161998, AN10060811 - 暗号への脅威「サイドチャネル攻撃」とその対策

IoTデバイスは、フィールドに配置される性質上、サイドチャネル攻撃などの物理攻撃にさらされやすい。一方、IoTデバイスは多種多様であり、セキュリティ対策に許容されるコストも様々である。本研究では、IoTデバイスを対象として、スケーラブルな物理セキュリティを実現する設計基盤と理論の構築を目的とする。この目的を達成するため、近似計算（Approximate Computing）技術をサイドチャネル攻撃対策に応用する。これにより、セキュリティの実装コストと安全性をトレードオフでき、多種多様なIoTデバイスを、それぞれ許容されるコストで保護することが可能となる。

Jun. 2018 - Mar. 2023 - Comprehensive study on anti-tamper techniques to prevent information leakage by laser fault injection attacks
Sakiyama Kazuo; VERBAUWHEDE Ingrid; DANGER Jean-Luc; BHASIN Shivam
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (A), The University of Electro-Communications, Grant-in-Aid for Scientific Research (A), Principal investigator, In this research, we have established fundamental countermeasure techniques against laser fault injection attacks, where an attacker intentionally induces soft errors in a cryptographic circuit to retrieve secret information. Specifically, we have conducted four research items; (1) construction of evaluation environment of laser fault injection attacks, (2) measurement of substrate potential fluctuation at laser irradiation and development of attack detection method, (3) development of countermeasure techniques for cryptographic-algorithm level based on detection, and (4) safety evaluation of countermeasure technology. We have deepened our understandings of the information leakage mechanism in the laser fault injection attack from physical and mathematical viewpoints and clarified the feasibility of countermeasure techniques using a prototype IC chip., 15H01688
Apr. 2015 - Mar. 2019 - Security Evaluation of Authentication Systems Using Side-Channel Information
Sakiyama Kazuo
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Challenging Exploratory Research, The University of Electro-Communications, Grant-in-Aid for Challenging Exploratory Research, Principal investigator, Previous work on side-channel information, physical information such as power leakage and electromagnetic waves leaked from a cryptographic system, focused on a case study of attacks that analyzed a part of side channel information and acquired a secret key. On the other hand, in this research project, we changed the way of thinking about side-channel information and set up a research framework that effectively utilizes all of the side-channel information. As an application, we proposed and constructed a new cryptosystem such as an authentication system, a ranging device, and an intrusion detection device using side-channel information, and demonstrated the enhancement of security. A series of efforts and understandings on this research topic has contributed to the development of side-channel analysis research., 15K12035
Apr. 2015 - Mar. 2018 - Development of Side-Channel Attack Sensing Techniques and Prototyping toward Electromagnetic Security of Cryptographic VLSI Circuits
Nagata Makoto; Danger Jean-Luc
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (A), Kobe University, Grant-in-Aid for Scientific Research (A), Coinvestigator, Cryptographic VLSI techniques have been established for assuring electromagnetic security with remarkably high tamper resistance against side-channel attacks. Three research items include: (1) On-chip detection of the proximate placement and approach of electromagnetic micro probes as the side-channel attack sensing technique, (2) integrated simulation techniques of electromagnetic coupling between the electromagnetic micro probe and on-chip side-channel sensors and also circuit operations, (3) positive usage of side-channel information for the authentication of cryptographic cores. These research items have been successfully completed and demonstrated with the fabricated integrated-circuit (IC) chips and prototype systems., 26240005
