Side Channel Cryptanalysis of Product Ciphers

Keywords : side channels, cryptanablysis, timing attacks, product ciphers
Abstract : Building on the work of Kocher [Koc96], we introduce the notion of side-channel cryptanalysis: cryptanalysis using implementation data. We discuss the notion of side-channel attacks and the vulnerabilities they introduce, demonstrate side-channel attacks against three product ciphers - timing attack against IDEA, processor-flag attack against RC5, and Hamming weight attack against DES - and then generalize our research to other cryptosystems.
