Abstract:

Hardware implementations of cryptographic systems are becoming more and more popular, due to new market needs and to reduce costs. However, system security may be seriously compromised by implementation attacks, such as side channel analysis or fault analysis. Fault-based side-channel cryptanalysis is very effective against symmetric and asymmetric encryption algorithms. Although hardware and time redundancy based Concurrent Error Detection (CED) architectures can be used to thwart such attacks, they entail significant overheads. In this paper we investigate systematic approaches to low-cost CED techniques for symmetric encryption algorithm PP-2, based on inverse relationships that exist between encryption and decryption at algorithm level, round level, and operation level. We show architectures that explore tradeoffs among performance penalty, area overhead, and fault detection latency.
