# Modular FROST
|
|
|
|
A modular implementation of FROST for any curve with a ff/group API.
|
|
Additionally, custom algorithms may be specified so any signature reducible to
|
|
Schnorr-like may be used with FROST.
|
|
|
|
A Schnorr algorithm is provided, of the form (R, s) where `s = r + cx`, which
|
|
allows specifying the challenge format. This is intended to easily allow
|
|
integrating with existing systems.
|
|
|
|
This library offers ciphersuites compatible with the
|
|
[IETF draft](https://github.com/cfrg/draft-irtf-cfrg-frost). Currently, version
|
|
15 is supported.
|
|
|
|
This library was
|
|
[audited by Cypher Stack in March 2023](https://github.com/serai-dex/serai/raw/e1bb2c191b7123fd260d008e31656d090d559d21/audits/Cypher%20Stack%20crypto%20March%202023/Audit.pdf),
|
|
culminating in commit
|
|
[669d2dbffc1dafb82a09d9419ea182667115df06](https://github.com/serai-dex/serai/tree/669d2dbffc1dafb82a09d9419ea182667115df06).
|
|
Any subsequent changes have not undergone auditing. While this audit included
|
|
FROST's definition of Ed448, the underlying Ed448 ciphersuite (offered by the
|
|
ciphersuite crate) was not audited, nor was the minimal-ed448 crate implementing
|
|
the curve itself.
