Web2.1.1 Attack Models. The same attack models apply here. Although an encryption function is automatically given to each principal, nothing immediately guarantees that adversaries have access to a decryption function. As before, Chosen Ciphertext Attack (CCA) and Chosen Ciphertext Attack 2 (CCA2) apply, and CCA2 implies Non-Malleability, as before. WebAttacks Against Cryptographic Designs A cryptographic system can only be as strong as the encryption algorithms, digital signature algorithms, one-way hash functions, and message authentication codes it relies on. Break any of them, and you’ve broken the system.

WebIt is however a stronger attack model than a chosen plaintext attack, and the strongest of all four here (but there are even stronger models outside the scope of your question, such as related-key attacks). ... Chosen plaintext/ciphertext attacks are somewhat exclusive to the modern ages of cryptography. In the past, such oracles were difficult ...

Some common attack models are: Ciphertext-only attack (COA) - in this type of attack it is assumed that the cryptanalyst has access only to the ciphertext, and has no access to the plaintext. This type of attack is the most likely case encountered in real life cryptanalysis, but is the weakest attack because of the … See more In cryptanalysis, attack models or attack types are a classification of cryptographic attacks specifying the kind of access a cryptanalyst has to a system under attack when attempting to "break" an encrypted message (also … See more • Niels Ferguson; Bruce Schneier (2003).
