Towards Automated Proofs for Asymmetric Encryption Schemes in the Random Oracle Model
Résumé
Chosen-ciphertext security is by now a standard security property for asymmetric encryption. Many generic constructions for building secure cryptosystems from primitives with lower level of security have been proposed. Providing security proofs has also become standard practice. There is, however , a lack of automated verification procedures that analyze such cryptosystems and provide security proofs. This paper presents an automated procedure for analyzing generic asymmetric encryption schemes in the random oracle model. This procedure has been applied to several examples of en-cryption schemes among which the construction of Bellare
