摘要: In this paper we analyse the Digital Signature Algorithm (DSA) and its immunity to fault cryptanalysis that takes advantage of errors inducted into private key a. The focus our attention is on DSA scheme as it a widely adopted by research community, known be vulnerable type attack, but neither sound nor effective modifications improve have been proposed. consider new way implementing enhances in presence faults. Our proposal ensures inducting has no benefits since attacker cannot deduce any information about given erroneous signatures. overhead similar obvious countermeasure based signature verification. However, modification generates fewer security issues.
