Weak Cryptographic Signature

Abstract

오래된 Digital Signature Algorithm을 사용하지 마십시오.

Explanation

디지털 서명은 디지털 메시지의 진실성과 무결성을 확인하는 데 사용되는 기술입니다. DSA(Digital Signature Algorithm)는 오래되었으며 이제 더 이상 사용되지 않습니다. RSA와 같은 다른 디지털 서명 알고리즘과 달리 DSA는 본질적으로 취약합니다. DSA는 메시지당 비밀 값 k가 필요합니다. 이 값은 암호학적으로 임의적이어야 하고 비밀로 유지되어야 하며 절대 재사용되지 않아야 합니다. 공격자가 k 값을 추측할 수 있는 경우 또는 제공된 값을 대신 사용하도록 서명자를 속일 수 있는 경우 개인 키를 복구한 다음 서명을 위조하여 합법적인 서명자로 가장할 수 있습니다. 마찬가지로, 공격자는 k 값이 여러 메시지에 서명하는 데 재사용되는 경우 개인 키를 복구할 수 있습니다.
