[GitHub] [incubator-milagro-crypto-c] aadomn opened a new issue, #112: Add proof of possession for BLS public keys
aadomn opened a new issue, #112:
URL: https://github.com/apache/incubator-milagro-crypto-c/issues/112
# Goal
BLS signatures come in three flavours: signature schemes: basic, message augmentation, and proof of possession.
The proof of possession variant requires three additional functions beyond the standard API:
- `PopProve(SK) -> proof`: an algorithm that generates a proof of possession for the public key corresponding to secret key SK.
- `PopVerify(PK, proof) -> VALID or INVALID`: an algorithm that outputs VALID if proof is valid for PK, and INVALID otherwise.
- `FastAggregateVerify((PK_1, ..., PK_n), message, signature) -> VALID or INVALID`: a verification algorithm for the aggregate of multiple signatures on the same message.
The goal of this issue is to implement these functions.
# Resources
[Draft RFC BLS](https://www.ietf.org/archive/id/draft-irtf-cfrg-bls-signature-05.txt) ยง3.3
# Deliverables
The three functions listed above, in both minimal-pubkey-size and minimal-sig-size settings.
# Acceptance criteria
1. Well documented code
2. The tests pass with 80% coverage
3. Clean sonarqube report
4. Review by at least 2 team members
