Accepting request 635471 from home:kbabioch:branches:security:privacy
- Update to version 1.0.8:
First of all, passive support for ECDSA, ECDH, and EdDSA (cf. RFC 6637
and Werner Koch's draft RFC 4880bis) has been added by relying on the
most recent version of LibTMCG. The threshold signature scheme and the
threshold encryption are still limited to finite field cryptography
(i.e. DSA and ElGamal). Moreover, the programs generate and recognize
a few other new OpenPGP features (e.g. issuer fingerprint subpackets)
from RFC 4880bis. Compressed messages are now decompressed by the
program dkg-decrypt using zlib Compression Library (and optionally by
library routines from libbzip2). This completes DKGPG's compatibility
with other OpenPGP software, however, the prefered compression algorithm
(i.e. "no compression") in self-signatures of generated keys is kept
for now. Support for symmetric-key decryption by dkg-decrypt has been
added too. The program dkg-verify now reads the signature from a file,
if option "-s" is used. To keep track of later protocol changes, all
interactive programs include a version identifier in their common ID of
the reliable broadcast channel. Thus programs from previous releases
will not communicate with those of this release. With the new programs
dkg-timestamp and dkg-timestamp-verify a OpenPGP timestamp signature
can be generated and verified, respectively. Last but not least, by the
new option "-y" some programs (dkg-generate, dkg-decrypt, dkg-sign,
dkg-keysign, and dkg-timestamp) will work with regular OpenPGP keys too.
The README file contains a configuration sample showing how to replace
classic PGP by DKGPG in the famous mail user agent mutt based on this
option. Please note that this feature is experimental and semantics
may be changed later.
- Added new build requirements:
* zlib
* bzip2

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.
