Abstract

Disclosed is an offline/online signature system including a key distribution center (KDC) and a signature end, wherein the KDC includes a key generating module, an offline signature module, and a verification module; and the signature end includes an online signature module and a verification module. The key generating module generates a temporary signature required for online signature, and transmits the result to a sensor node for storage. The online signature module generates a signature for a specific message; and the verification module includes a processor and a public key transformation component, wherein the processor transmits the signature to the public key transformation component and determines whether the signature is valid.
