Against fault attacks based on random infection mechanism

Abstract

Fault attack is a very effective way to crack the key for cipher chip. Among existing fault attack countermeasures, the infection countermeasures are very effective means, but, most existing infection countermeasures are based on the single fault assumption, and the accuracy of fault injections has significantly improved in the late years, it has become possible to implementation of double fault attacks in specific circuit regions, and it is, therefore, flawed in the resistance to double fault attacks. Aim at the flawed mentioned, this paper proposes a countermeasure called random infection mechanism to resist fault attacks. We use the encryption/decryption circuit to construct the fault diffusion pattern and avoid under the possibility of double error attacks. Furthermore, in order to against single byte fault attacks, we introduce random numbers to make the fault diffusion randomization. Experiments are carried out to verify the proposed algorithm and the results show that the proposed random infection mechanism can resist fault attacks effectively including single byte error attacks.

Cyber attacks targeting electronic devices of power systems and countermeasures

“…In [22], a supervised learning approach against cyber attacks on demand side of power systems is proposed to achieve attack detection with the aid of the characteristics of the demand side attacks (DSA). Random infection mechanism is proposed to mitigate fault attacks using encryption/decryption circuit [23]. performance of side channel attack sensor is analyzed to improve the system security [24].…”

Research on a Random Mask Infection Countermeasure against Double Fault Attacks

“…This is because the detection locations are associated with the data being processed [21]. Another type of approach is the use of fault infection [22][23][24]. Since the infection strategy does not need to utilize the detection locations, it effectively avoids the potential threat of being attacked due to the presence of detection locations.…”

“…2023, 13, 12530 2 of 11 mechanism in [25] was deficient due to the same unknown mask being used in the infection process and improved on [25]. In 2019, by utilizing the encryption/decryption circuit, [22] proposed a countermeasure against fault attack called random infection mechanism.…”

“…Although it is difficult to inject the same fault for both encryption or decryption paths (in other words, it is difficult to perform a double-fault attack), with the development of fault injection accuracy, it has become possible to inject double faults [27]. Fortunately, researchers have recognized the threat of double-fault attacks and have discussed them to some extent [22,24,28,29]. In [24], when analyzing existing methods against fault attacks, the possibility of doublefault attacks on cryptographic circuits is clearly stated, but no specific countermeasure is given.…”

Tamper-resistant cryptographic hardware

“…An attacker who possesses a set of oscilloscope and personal computer can successfully derive the key information. Fault attacks [2,3] are attacks that exploit faulty cipher-text from a cryptographic module to guess the secret key. The fault operation is intentionally caused by injecting clock glitch, supplying abnormal voltage and irradiating a laser to the module.…”
