Multiple signature generation and verification system and method thereof

Abstract

The invention discloses a multiple signature generation and verification system and a method thereof. The multiple signature generation and verification system comprises an information releasing unit, a credible center, at least one signature unit, a signature collection unit and a signature verification unit. The information releasing unit generates information to be signed, and a signature unit listing used for signing. The credible center generates system public parameters. At least one signature unit is connected with the information releasing unit and the credible center in a communication mode and is used for generating a public key and a private key and generating corresponding partial signatures. The signature collection unit is connected with the information releasing unit, the signature unit and the signature verification unit in a communication mode. The signature verification unit is connected with the credible center and the signature collection unit in a communication mode and is used for verifying signature files according to the public parameters, the signature unit listing and the information. According to the multiple signature generation and verification system, each signature unit independently generates the partial signatures of the each signature unit, and the system is free from interaction, low in communication cost, and high in signing efficiency. The invention further discloses the multiple signature generation and verification method.

Description

technical field [0001] The invention belongs to the technical field of telecommunications, and in particular relates to a multi-signature generation and verification system and method thereof. Background technique [0002] Digital signatures are used for signature authentication of electronic documents stored on computers, and securely bind the content of electronic documents with the identity of the signer. Electronic documents include any file generated or stored on a computer, such as emails, contracts, works, images, etc. Only the real signer can generate a valid digital signature, and anyone can verify the signature generated by the signer to be sure that it was indeed signed by the signer. Digital signatures are widely used in e-commerce, e-government and other information services. In a digital signature system, it needs to be composed of three objects: message sender, message signer and signature verifier. In the computer network environment, the objects that perf...
