WebOct 1, 2024 · Recently, Zhao et al. proposed a semi-quantum bi-signature (SQBS) scheme based on W states with two quantum signers and just one classical verifier. In this study, we highlight three security issues with Zhao et al.’s SQBS scheme. In Zhao et al.’s SQBS protocol, an insider attacker can perform an impersonation attack in … WebA dictionary attack is a basic form of brute force hacking in which the attacker selects a target, then tests possible passwords against that individual’s username. The attack method itself is not technically considered a brute force attack, but it can play an important role in a bad actor’s password-cracking process.
