LibTMCG 1.2.0 released

Item posted by Heiko Stamer <stamer> on Sat 31 Dec 2016 04:29:51 PM UTC.

After a year of work we proudly present LibTMCG 1.2.0.

The default security parameters have been updated to current state of the art. The complexity of hash function g() was improved. Unfortunately, this breaks compatibility with instances that have been compiled with older versions of LibTMCG.

The configure switch --with-gmp has been added in order to find the required libgmp on a non-standard path (e.g. on MacOS).

Non-interactive versions of the verifiable shuffle resp. rotation protocol provide more efficient instantiations with soundness based on the well-known Fiat-Shamir heuristic. The interactive versions of the protocols have been strengthened against malicious verifiers by coin flipping between prover and verifier. Finally a protocol for reliable broadcast is now included.

Last but not least, the documentation has been improved.
