Abstract
A hypersphere-based multivariable public key signature/verification system includes signature and verification modules, wherein the signature module comprises a processor, an affine transformation inversion part I, a trap door part and an affine transformation inversion part II. Corresponding operations are sequentially executed on a message, one or more groups of solutions are produced after the processing of the trapdoor part, a group of solutions are randomly selected, then a signature is continuously produced by the various parts, and finally the signature, together with the message, is transmitted to the processor. The verification module comprises a processor and a public key transformation part, wherein the processor transmits a signature to the public key transformation part to execute an operation, and then judges whether the obtained data is equal to a message in a memory or not: if so, the signature is valid, otherwise the signature is invalid.
