Most approaches to the formal analyses of cryptographic protocols make the perfect cryptography assumption, i.e. the hypothese that there is no way to obtain knowledge about the plaintext pertaining to a ciphertext without knowing the key. Ideally, one would prefer to rely on a weaker hypothesis on the computational cost of gaining information about the plaintext pertaining to a ciphertext without...
Formal methods have been extensively applied to the certification of cryptographic protocols. However, most of these works make the perfect cryptography assumption, i.e. the hypothesis that there is no way to obtain knowledge about the plaintext pertaining to a ciphertext without knowing the key. A model that does not require the perfect cryptography assumption is the generic model and the random...
Most approaches to the formal analysis of cryptography protocols make the perfect cryptographic assumption, which entails for example that there is no way to obtain knowledge about the plaintext pertaining to a ciphertext without knowing the key. Ideally, one would prefer to abandon the perfect cryptography hypothesis and reason about the computational cost of breaking a cryptographic scheme by achieving...
