Prime Masking vs. Faults - Exponential Security Amplification against Selected Classes of Attacks

Transactions on Cryptographic Hardware and Embedded Systems
Fault injection attacks are a serious concern for cryptographic hardware. Adversaries may extract sensitive information from the faulty output that is produced by a cryptographic circuit after actively disturbing its computation.

Information Theory-Based Quantitative Evaluation Method for Countermeasures Against Fault Injection Attacks

IEEE Access, 2019
The integrated circuits are faced with the threats of fault injection attacks (FIAs), which employ the faulty results and differential fault analysis to retrieve the vital information processed by the circuits.

A fault-based attack on AEZ v4.2

, 2017
This paper investigates differential fault attacks against AEZ v4.2 authenticated encryption scheme. AEZ uses three different 128-bit keys (I, J, L) and can potentially work without a nonce or with a repeated nonce.

Multi-Stage Fault Attacks on Block Ciphers [PDF]

, 2013
This paper introduces Multi-Stage Fault Attacks, which allow Differential Fault Analysis of block ciphers having independent subkeys. Besides the specification of an algorithm implementing the technique, we show concrete applications to LED-128 and ...

Differential Fault Attacks against AES tampering with the Instruction Flow

, 2014
Most of the attacks against the Advanced Encryption Standard based on faults mainly aim at either altering the temporary value of the message or key during the computation.

Locking-Enabled Security Analysis of Cryptographic Circuits

Cryptography
Hardware implementations of cryptographic primitives require protection against physical attacks and supply chain threats. This raises the question of secure composability of different attack countermeasures, i.e., whether protecting a circuit against ...

Differential Fault Analysis Automation [PDF]

, 2017
Characterization of all possible faults in a cryptosystem exploitable for fault attacks is a problem which is of both theoretical and practical interest for the cryptographic community. The complete knowledge of exploitable fault space is desirable while
