Masking against Side-Channel Attacks: A Formal Security Proof
Abstract. Masking is a well-known countermeasure to protect block cipher implementations against side-channel attacks. The principle is.
Symmetric cryptanalysis ? from primitives to modes
Abstract: This memoir is dedicated to symmet- ric cryptanalysis, i.e., the security analysis of symmetric cryptosystems. We present attacks.
