Secret-key cryptography

Low Entropy Masking Scheme (LEMS) has attracted wide attention for its low-cost feature of small fixed mask sets in Side-Channel-Analysis (SCA). To achieve the expected side channel security, it is necessary to find a balanced mask set to reduce the correlations between key dependent variables and their corresponding leakages. However, the security proof of LEMS, based on an inadequate assumption, might lead to consequent mask sets proposed without balance property, which could cause...

Implementation

Rotating Sbox Masking (RSM) scheme is a highly efficient masking scheme proposed to protect cryptographic implementations from side channel attacks. It is a Low Entropy Masking Scheme and has attracted special attention for its low overhead but high performance. The two public targets of international academic competition DPA Contest v4 are both RSM-masked AES implementations, specifically, RSM-AES-256 for v4.1 and RSM-AES-128 for v4.2 respectively. The side channel security of RSM-AES-256...
