Distributed Key Generation (DKG) and Threshold Cryptography for OpenPGP


Productivity/Security

The Distributed Privacy Guard (DKGPG) implements Distributed Key Generation (DKG) and Threshold Cryptography for OpenPGP. The generated public keys are RFC4880 compatible and can be used by e.g. GnuPG. The main purpose of this software is distributing power among multiple parties, eliminating single points of failure, and increasing the difficulty of side-channel attacks on private key material.

DKGPG consists of a number of command-line programs. The current implementation is in experimental state and should NOT be used in production environments.

A shared private key and a common public key (currently only DSA/ElGamal) are generated. Further interactive protocols perform the private operations like decryption and signing of files, provided that a previously defined threshold of parties/devices take part in the distributed computation. Due to the interactiveness of the protocols, a lot of messages between participating parties have to be exchanged in a secure way. GNUnet's mesh-routed CADET srvice is used to establish private and broadcast channels for this message exchange. A TCP/IP-based service is included as an alternative. It may be combined with torsocks and NAT of a local hidden service.
