Abstract
Disclosed are an interactive aggregate signature method, and a device and a storage medium, which relate to the technical field of data encryption. The method comprises: S101, generating a challenge number according to random numbers of all participating terminals, and respectively sending the random numbers corresponding to the participating terminals, the challenge number and a proposal message to corresponding participating terminals; S102, receiving a message from the participating terminals, and if partial signatures are included in the message, recording the partial signatures; S103, determining whether the number of recorded partial signatures reaches a number required for passing of the proposal message; if so, proceeding to S104, involving generating an aggregate signature by means of the partial signatures; and if not, outputting that the proposal message fails to be passed and an aggregate signature cannot be generated, or repeating steps S101 to S103.
