Biased ECDSA Nonce Generation

PuTTYis vulnerable to biased ECDSA nonce generation. The vulnerability is due to biased ECDSA nonce generation, allowing an attacker to recover a user's NIST P-521 secret key via a quick attack in approximately 60 signatures. This is particularly significant in scenarios where an adversary can re...
