Cryptology vs. Cryptography: What

WebDifferential cryptanalysis is a chosen-plaintext attack. In this model, the attacker is able to make a cryptosystem encrypt data of his choosing using the target key (which is the secret). By analyzing the results that come back (the known ciphertext), the attacker can determine the key being used. ... So for example, if knownP 5 XOR knownP 34 ... WebJan 3, 2024 · There are three generic forms of cryptanalysis: ciphertext-only, known ciphertext/plaintext pairs and chosen plaintext or chosen ciphertext.

The substitution cipher is more complicated than the Caesar and Affine ciphers. In those cases, the number of keys were 25 and 311 respectively. This allowed a brute force solution of trying all possible keys.
