  • v0.11.4   Verifpal 0.11.4 In this release, we build upon the performance improvements introduced in Verifpal 0.11.3 and offer even faster analysis. Overall, Verifpal 0.11.4 is dramatically, almost incomparably faster than Verifpal 0.11.2 and previous versions.

  • v0.11.3   Verifpal 0.11.3 Verifpal 0.11.3 brings dramatic analysis speed improvements across the board, thanks to some optimizations to the heuristics logic and the rewriting of some core functions.

  • v0.11.0   Verifpal 0.11.0 In this release, major improvements are made to Verifpal's stability and performance, thanks to analysis code optimizations and the elimination of some race conditions that could appear in rare conditions.
  • v0.10.8   Verifpal 0.10.8 In this release, improvements are made to the heuristics that Verifpal uses in order to attempt to shorten analysis time and avoid state space explosions. The result should be significantly faster analysis for most models.

  • v0.10.7   Verifpal 0.10.7 In this release, we attempt a new approach at dealing with state space explosions: bounding the analysis exclusively on HKDF primitive mutations, while keeping the analysis unbounded on everything else.

  • v0.10.6   Verifpal 0.10.6 In this release, we add experimental support for a new ring signatures primitive, as suggested by Sebastian R. Verschoor: https://lists.symbolic.software/pipermail/verifpal/2020/000157.html Two primitives are added: - RINGSIGN(key_a, G^key_b, G^key_c, message): signature. In ring signatures, one of three parties (Alice, Bob and Charlie) signs a message. The resulting signature can be verified using the public key of any of the three parties, and the signature does not reveal the signatory, only that they are a member of the signing ring (Alice, Bob or Charlie). The first key must be the private key of the actual signer, while the subsequent two keys must be the public keys of the other potential signers. - RINGSIGNVERIF(G^a, G^b, G^c, m, RINGSIGN(a, G^b, G^c, m)). Verifies if a ring signature can be authenticated. The signer's public key must match one or more of the public keys provided, but the public keys may be provided in any order and not necessarily in the order used during the RINGSIGN operation.

  • v0.10.5   Verifpal 0.10.5 In this release, we add the new "leaks" expression, which allows principals to leak values to the attacker without necessarily sending them to one another over the network, like this: principal Alice[ knows private verySecretSecret leaks verySecretSecret ] The attacker now knows verySecretSecret. Other minor improvements and optimizations are included.

  • v0.10.4   Verifpal 0.10.4 In this release, the heuristics added in 0.10.3 to constrain HKDF mutation state explosion are relaxed in order to reduce missed attacks. Two new tests, subkey_hash.vp and subkey_hkdf.vp, are added in order to ensure that these missed attacks do not recur.

  • v0.10.3   Verifpal 0.10.3 In this release, we continue the 0.10.x trend of focusing on a more comprehensive analysis. 0.10.2 improved the scope of the analysis by allowing HKDF values to be mutated by the attacker, but this introduced an enormous state space explosion overhead. In 0.10.3, we improve the heuristics used by Verifpal in order to attempt to reduce the potential for state space explosion and keep analysis fast/actually terminating. Heuristic improvements come at the risk of reduced analysis completeness, something which we will need to continue to evaluate as Verifpal grows.
