WebOne attack against a number of different cryptographic methods is called the Known Plaintext Attack, or KPA. This is when the attacker has, obviously, the encrypted information but they also might have a little bit of the plaintext– something that they were able to discern perhaps in some other way. WebSep 1, 2024 · Put simply, it’s a way to make information unreadable by attackers, even if it is compromised. What is Cryptography? Cryptography in computer network security is the process of protecting sensitive information from unauthorized access when it is at rest or in transit by rendering it unreadable without a key.
