Attack model
From Wikipedia, the free encyclopedia
Attack models or attack types specify how much information a cryptanalyst has access to when cracking an encrypted message. Some common attack models are:
The ciphertext-only attack model is the weakest because it implies that the cryptanalyst has just the encoded message.
Different attack models are used for other cryptographic primitives, or more generally for all kind of security systems. Examples for such attack models are:
