Combined Fault and Side-Channel Attack on Protected Implementations of AES
The contribution of this paper is twofold: (1) a novel fault injection attack against AES, based on a new fault model, is proposed. Compared to state-of-the-art attacks, this fault model advantage is to relax constraints on the fault location, and then reduce the a priori knowledge on the implementation. Moreover, the attack algorithm is very simple and leaves room for optimization with respect...
متن کاملNew side-channel attack against scan chains
Insertion of scan chains is the most common technique to ensure observability and controllability of sequential elements in an IC. However, when the chip deals with secret information, the scan chain can be used as back door for accessing secret (or hidden) information, and thus jeopardize the overall security. Several scan-based attacks on cryptographic functions have been described and shown ...
متن کاملSide Channel Attacks on Implementations of Curve-Based Cryptographic Primitives
The present survey deals with the recent research in side channel analysis and related attacks on implementations of cryptographic primitives. The focus is on software contermeasures for primitives built around algebraic groups. Many countermeasures are described, together with their extent of applicability, and their weaknesses. Some suggestions are made, conclusion are drawn, some directions ...
متن کاملSide-Channel Attacks on Threshold Implementations Using a Glitch Algebra
Threshold implementations allow to implement circuits using secret sharing in a way to thwart side-channel attacks based on probing or power analysis. It was proven they resist to attacks based on glitches as well. In this report, we show the limitations of these results. Concretely, this approach proves security against attacks which use the average power consumption of an isolated circuit. Bu...
متن کاملScan Based Side Channel Attack on Data Encryption Standard
Scan based test is a double edged sword. On one hand, it is a powerful test technique. On the other hand, it is an equally powerful attack tool. In this paper we show that scan chains can be used as a side channel to recover secret keys from a hardware implementation of the Data Encryption Standard (DES). By loading pairs of known plaintexts with one-bit difference in the normal mode and then s...
