Algorithmic Countermeasures Against Fault Attacks and Power Analysis for RSA-CRT
In this work, we analyze all existing RSA-CRT countermeasures against the Bellcore attack that use binary self-secure exponentiation algorithms. We test their security against a powerful adversary by simulating fault injections in a fault model that includes random, zeroing, and skipping faults at all possible fault locations. We find that most of the countermeasures are vulnerable and do not p...
متن کاملUsing State Space Encoding To Counter Biased Fault Attacks on AES Countermeasures
Biased fault attacks such as the Differential Fault Intensity Analysis (DFIA) have been a major threat to cryptosystems in recent times. DFIA combines principles of side channel analysis and fault attacks to try and extract the key using faulty ciphertexts only. Biased fault attacks have also been shown to weaken traditional redundancy based countermeasures, such as Concurrent Error Detection (...
متن کاملFault Attacks on RSA with CRT: Concrete Results and Practical Countermeasures
This article describes concrete results and practically validated countermeasures concerning differential fault attacks on RSA using the CRT. We investigate smartcards with an RSA coprocessor where any hardware countermeasures to defeat fault attacks have been switched off. This scenario was chosen in order to analyze the reliability of software countermeasures. We start by describing our labor...
متن کاملProgrammable and Parallel ECC Coprocessor Architecture: Tradeoffs between Area, Speed and Security
Elliptic Curve Cryptography implementations are known to be vulnerable to various side-channel attacks and fault injection attacks, and many countermeasures have been proposed. However, selecting and integrating a set of countermeasures targeting multiple attacks into an ECC design is far from trivial. Security, performance and cost need to be considered together. In this paper, we describe a g...
متن کاملPractical Fault Countermeasures for Chinese Remaindering Based RSA
Most implementations of the widely-used RSA cryptosystem rely on Chinese remaindering (CRT) as this greatly improves the performances in both running times and memory requirements. Unfortunately, CRT-based implementations are also known to be more sensitive to fault attacks: a single fault in an RSA exponentiation may reveal the secret prime factors trough a GCD computation, that is, a total br...
متن کاملFault Attack and Countermeasures on Pairing Based Cryptography
Bilinear pairing is a new and increasingly popular way of constructing cryptographic protocols. This has resulted in the development of Identity Based Encryption (IBE) that is ideally used in identity aware devices. The security of such devices using pairing algorithms against side-channel and fault attack has not been studied extensively. This paper examines the security of existing countermea...
