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.
