      Aries-Framework-Go #aries-go
    • 2020-11-03 Meeting Notes
    • BBS+ Verifiable Credentials implemented using pure Go. Example.
      • Next tasks: interop testing against Mattr implementation and selective disclosure capabilities.
    • Working on adding remote encrypted storage capability - with a default implementation of DIF Secure Data Storage - Encrypted Data Vaults.
      • Encrypted Data Vault (EDV) from DIF SDS spec format has been implemented. Works as an encryption wrapper to underlying storage providers.
      • DIF EDV/SDS REST client is in progress. Docker image will support configuring EDV endpoint as wallet storage.
    • Remote KMS support is in progress. Docker image will support configuring remote KMS. 
      • Created repo to handle pluggable go framework components such as Indy VDR: https://github.com/hyperledger/aries-framework-go-ext
    • MySQL and CouchDB components moved to ext repo.
      • New contributions of MongoDB and RabbitMQ support to the ext repo.
    • Tools
  • Hyperledger Ursa
    • Homepage:  Hyperledger Ursa (EOL) 
    • 20202021-1201-8 06 Meeting Agenda
      • Approved the secret sharing PR.
      • Accumulator discussion.
      • Outstanding issues:  
        1. k256 crate. 
          1. Already migrated for the signature refactor.
          2. Can Milagro be removed?  (Only left for Indy.)
        2. Ursa refactor.
        3. Revocation issues (led by Brent)
        4. IETF Standardizing BLS Signatures
      • Distributed BBS+:  (https://www.orbs.com/wp-content/uploads/2019/04/Crypto_Group_signatures-2.pdf
      • Signature structure and types:
        1. "Simple" Signatures:  KeyGen, Sign, Verify.
        2. Blind Signatures.  KeyGen, Blind, Sign, (Blinded Sign?), Unblind, Verify.
        3. Threshold Signatures.  KeyGen (more complicated), SignShare, Combine, Verify.
          1. Multi-round threshold signature.  Can have extra definition for interactive protocols.  
          2. Can have multiple types of KeyGen.  
        4. Multisignatures.  Multiple signers have signed THE SAME message.
        5. Aggregate signatures.  Multiple signers have signed potentially different messages.
        6. Short group signatures.  Need precise definitions.
      • How should we handle MPC and communication?
        1. Secure channel operations.  How about ratcheting?
        2. Example:  ECDSA.
        Discussion on PR #143 (is there still interest?)
