The present invention relates to the technical field of communications. Disclosed are a certificateless multi-agent signature method and apparatus, which solve the problem of a large amount of calculation of a certificateless multi-agent signature in a bilinear manner. The method of the present invention may specifically include: an agent signature device calculating a public key and a private key of the agent signature device according to open parameters, the public key being corresponding to the private key; acquiring an authentication result of a standard signature, and determining, according to the authentication result, whether the standard signature is valid; if the authentication result indicates that the standard signature is valid, calculating, according to the private key, a partial agent signature of the agent signature device; sending the partial agent signature to an agent signature device manager, so that after the agent signature device manager calculates a multi-agent signature according to the partial agent signature, a multi-agent signature authentication device authenticates the multi-agent signature. The present invention can be applied to a certificateless multi-agent signature. |
