WebApr 25, 2024 · This module studies the attacker view whose objective is to learn the key and break the cryptographic protection using the key. First, we will define brute force attack and describe how to quantify the attacker effort for brute force attack. Next, we will contrast cryptanalysis and brute force attack. WebSo here we get 18a ≡ 12 (mod 2) and 18a ≡ 12 (mod13) or, reducing, 0a ≡ 0 (mod 2) and 5a ≡ 12 (mod13) The first is a tautology, and the second can be solved by multiplying …
