Side Channel Cryptanalysis of Product Ciphers

Journal of Computer Security, v. 8, n. 2-3, 2000, pp. 141-158.

ABSTRACT: Building on the work of Kocher, 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.
