摘要

Physical attacks through hardware bit probing expose significant vulnerabilities in cryptographic systems. This paper investigates the leakage resilience of linear code-based secret sharing schemes, including Shamir’s secret sharing, under the threat of physical-bit leakages. Our focus is on schemes over binary extension fields, which are prevalent in practical cryptographic applications. We present the following key results:
