Crypto Review panel
Lots of good reviews done
Re-keying mechanisms for symmetric keys, Stanislav Smyshlyaev
Explanation of goals, response to reviews and feedback. Plan to get version addressing existing reviews by end of January.
Q&A about how to signal re-key in, for example, non-TLS uses
Transition from classical to Post-Quantum Cryptography, Paul Hoffman
(Last time Kenny spoke, Paul wasn’t present; this time Paul’s present and Kenny isn’t. Hmm)
Helping people who like to make predictions, make predictions
Proposed CFRG adoption. Consensus in room was strongly in favor, some need more info. To be confirmed on the list.
Q&A about num of qubits needed for 2K RSA, possibility of multiple smaller-sized machines, and practicality of using (much) larger curves with existing algorithms
Get your friends to help review and/or provide content!
SPAKE2, a PAKE, Benjamin Kaduk
Expired back in February 2016, and Ben picked it up and has a new version coming out
Initial use-case is KRB pre-auth before getting a ticket; there’s others
Q&A on tech details, and pointing out the “pake requirements” RFC that this should reference
PEKX, Public Key Exchange Dan Harkins
Define a way to exchange ‘raw’ public keys, including auth and binding an identity
Has had crypto review, has interoperable implementations
Looking to have CFRG adoption; insufficient readers in room, will take to the list
Q&A about identity, binding to key etc
Cryptographically traversable blockchains or ‘skipchains’ Bryan Ford
Addressing problem of efficient verification of block chains – how to “catch up” on state
See “Chainiac” paper in Usenix Security 2017 proceedings (which has more than just the skipchain cryptographic structure)
Q&A about signing roster changes, and picking trusted entities (see paper)
