A Probabilistic Hoare-style logic for Game-based Cryptographic Proofs (Extended Version)
Ricardo Corin and Jerry den Hartog
Abstract: We extend a Probabilistic Hoare-style logic to formalize game-based
cryptographic proofs. Our approach provides a systematic and rigorous
framework, thus preventing errors from being introduced. We illustrate
our technique by proving semantic security of ElGamal.
