WebJan 4, 2024 · An attacker collects the hash and the digital signature for all 60000 pieces of software. The attacker writes their own trojan malware with some spare padding at the end of their executable file. The attacker calculates a partial hash of their executable, but stops (saving hash calculation state) just before the padding. WebThe notion of 'balance' of a hash function quantifies the resistance of the function to birthday attacks and allows the vulnerability of popular hashes such as MD and SHA to be estimated (Bellare and Kohno, 2004). Digital signature susceptibility. Digital signatures can be susceptible to a birthday attack.
