EasyCrypt: Computer-Aided Cryptographic Proofs

Overview

EasyCrypt is a toolset for reasoning about relational properties of probabilistic computations with adversarial code. Its main application is the construction and verification of game-based cryptographic proofs. Initial applications of EasyCrypt focus on encryption and signature schemes.

However, the initial prototype has been extended significantly to reason about the security of cryptographic systems, which achieve specific functionalities through intricate combinations of several primitives. These developments have expanded significantly the scope of potential applications of EasyCrypt, as reflected in our recent formalization of secure function evaluation and verifiable computation. Moreover, they have enabled the formalization of examples that were previously out of scope, for instance modular proofs of security for key-exchange protocols.

Downloads

The current release of EasyCrypt (version 1.0) is still under development. Please join the EasyCrypt club mailing list to be informed of evolutions.

You can get EasyCrypt via our public git repository (browse):

git clone https://github.com/EasyCrypt/easycrypt.git

Installation instructions can be found in the README file, and some tutorial material is available, as well as a reference manual (under development).

Note that the current release of EasyCrypt (version 1.0) is still being actively developed. We do not guarantee backwards compatibility.

EasyCrypt 0.2

You can also download EasyCrypt version 0.2 and its documentation. However, we are no longer actively supporting this version, and recommend switching to version 1.0.
