LibTMCG 1.3.2 released

Item posted by Heiko Stamer <stamer> on Sun 03 Sep 2017 11:57:53 AM UTC.

Major improvements for distributed key generation (DKG) and threshold cryptography have been added. For example, the robust DSA compatible threshold signature scheme of Canetti et al. is now included. LibTMCG contains an implementation (called DKG-tools) of these protocols that provides threshold decryption and signatures for OpenPGP (RFC 4880). However, such schemes are of independent interest and can be used for distributed electronic card games (e.g. drop-out tolerance) as well. Finally some bugfixes improve the robustness of the reliable broadcast protocol (RBC) and portability for OpenBSD.
