On: 2017 Levchin Prize for Real World Cryptography

[tptacek]

Moxie Marlinspike and Trevor Perrin. Most of the novel cryptography in Signal Protocol is Trevor's; it's good for people to know who he is.

Reprising a previous thread:

The prizes went to Joan Daemen, for AES and SHA-3 (on stage, Levchin pointed out that his interest in cryptography had been piqued by a xeroxed copy of DES when he was in school, and that it was an honor to present an award to one of the people who replaced the DES), and --- more notably, I think --- to Moxie Marlinspike and Trevor Perrin for their work on Signal.

Last year's winners were Phil Rogaway (a cryptographer of repute comparable to that of Daemen) and the miTLS team (of Triple Handshake, SMACK, FREAK, Logjam, and SLOTH fame).

Trevor Perrin also went on and created the Noise protocol framework (of which some protocols are quite similar to Signal).

[RRRA → dom0]

Interesting, didn't know he was also involved with that one.

Has anyone seen a table comparing Noise, Axoltl & OTRv4?

[tptacek → RRRA]

Those aren't comparable.

Noise is a metaprotocol, a framework of patterns for building secure transports.

Axolotl is a cryptographic ratchet construction, for continuously modifying encryption keys as messages are transmitted.

OTRv4 is a complete message cryptosystem, like Signal Protocol.
