Much of January was spent, > unfortunately, dealing with the personal repercussions of an unexpected EO. > > > The following progress was made in (late) January through February 2017: > > - The specification for elliptic curve zero-knowledge proof-of-knowledge of > discrete logarithm equality was laid out in writing. We also shared this > construction publicly with other cryptographers on the Trevor Perrin's > curves mailing list, [0] since both Tony Arcieri of Chain and George > Tankersley of Cloudflare were looking to use the same construction. > > - Outlined code for the above zero-knowledge proofs, and refactored some of > the algebraic MAC and anonymous credential code. > > - Begun setting up domain fronting for BridgeDB. > > - More detailed documentation on our elliptic curve library, > curve25519-dalek, as well as progress on the paper/specification for the > cryptographyic requirements of our bridge distribution scheme. [1] > > - Extended functionality for curve25519-dalek to ease implementation of the > Elligator2 birational map (which we require) and other features necessary > for a potential external implementation of VXEdDSA (which is useful to > Signal and other projects). [2] > > - Finished a ~~beta~~ implementation of Decaf [3] for curve25519. [4] Since > we know of no other implementations which compiles, we are looking forward > to further testing and review. NCC Group has potentially (and generously) > offered to audit our cryptographic work, since (as mentioned above) other > companies are intending to use it. For now, we'll call it extremely > yolocrypto beta, and base our prototype off of it. > > - Finished the API for new Bridge Distributors and deployed to production. > [5] > > - We (maybe) found more bugs in other open source crypto! We feel a bit > crunched trying to get the rest of our project done in the next seven > weeks, > but we'll be working with those teams to ensure that everything is sound > and everyone is safer. > > > [0]: https://moderncrypto.org/mail-archive/curves/2017/000853.html > [1]: > https://fyb.patternsinthevoid.net/curve25519-dalek/curve25519_dalek/decaf/index.html > [2]: > https://github.com/isislovecruft/curve25519-dalek/commits?author=isislovecruft&since=2017-02-01T00:00:00Z&until=2017-03-01T00:00:00Z > [3]: https://mikehamburg.com/papers/decaf/decaf.pdf > [4]: > https://github.com/isislovecruft/curve25519-dalek/blob/master/src/decaf.rs > [5]: > https://gitweb.torproject.org/user/isis/bridgedb.git/tree/bridgedb/distribute.py > > Best, > -- > ♥Ⓐ isis agora lovecruft > _________________________________________________________ > OpenPGP: 4096R/0A6A58A14B5946ABDE18E207A3ADB67A2CDB8B35 > Current Keys: https://fyb.patternsinthevoid.net/isis.txt ----- End forwarded message ----- -- ♥Ⓐ isis agora lovecruft _________________________________________________________ OpenPGP: 4096R/0A6A58A14B5946ABDE18E207A3ADB67A2CDB8B35 Current Keys: https://fyb.patternsinthevoid.net/isis.txt
