Secure Distributed Samplers for Cryptographic Reference Strings

Original (Chinese)

The disclosed technology pertains to a method and system for generating a common reference string for use by multiple parties in cryptographic operations. The method involves executing a generation algorithm that creates encryption and decryption codes, generates non-interactive zero-knowledge proofs, and outputs a message for each party. These messages are published to a public domain and accessed by all parties. A derivation algorithm is then executed at each party to derive a common reference string from the set of messages by combining them. The system comprises a computerized processor configured to execute these algorithms. The common reference string is stored in a computerized storage device.
