Layer 3: Interactive Protocols

The Interactive Protocol layer contains interactive protocols which can be used as a standalone protocols or as building blocks of higher cryptographic schemes. The protocols in this layer are two-party protocols, meaning that there are two participants in the protocol execution when each one has a different role. For example, OT protocol consists of a sender and a receiver, ZK protocol consists of a prover and a verifier, etc. The communication between the parties is done through the SCAPI’s Communication Layer.

This layer contains the following components:

• Oblivious Transfer Protocols
  • Class Hierarchy
  • Basic Usage
• Sigma Protocols
  • The Prover class
  • The Verifier class
  • The Simulator class
  • Computation classes
  • Supported Protocols
  • Example of Usage
• Zero Knowledge Proofs and Zero Knowledge Proofs of Knowledge
  • Zero Knowledge abstract classes
  • Zero Knowledge Proof of Knowledge classes
  • Implemented Protocols

• Commitment Schemes
  • The Committer class
  • The Receiver class
