Description
CryptoVerif is an automatic protocol prover sound in the computational model. It can prove
- secrecy;
- correspondences, which include in particular authentication;
- indistinguishability between two games.
It provides a generic mechanism for specifying the security assumptions on cryptographic primitives, which can handle in particular symmetric encryption, message authentication codes, public-key encryption, signatures, hash functions.
The generated proofs are proofs by sequences of games, as used by cryptographers. These proofs are valid for a number of sessions polynomial in the security parameter, in the presence of an active adversary. CryptoVerif can also evaluate the probability of success of an attack against the protocol as a function of the probability of breaking each cryptographic primitive and of the number of sessions (exact security).
This software is under development; please use it at your own risk. Comments and bug reports welcome.

This directory contains examples for the translation from
CryptoVerif assumptions to EasyCrypt.
- To generate the EasyCrypt files, run `make ec`. The files are put
in directory `generated`.
- To check the generated files / proofs, you can you run `make
test-$x` where $x can take the following values:
- common: check the core EasyCrypt files located in common/
- generated: check the generated files located in generated/
- proofs: check the proofs located in proofs/
- proofs-fast: same as `proofs` with the exception of GDH_RSR.
(The checking time of this example is very long)
- all: common+generated+proofs
- all-fast: common+generated+proofs-fast
The proofs have been verified with EasyCrypt commit
068fdd9c984c344c1b4a44f9f6455f41ee437a30 [1] that was
configured with the 3 following provers:
- Alt-Ergo@2.4.2
- Z3@4.12.2
- CVC4@1.6
using Why3@1.7.0
