An electronic signature method using bilinear mapping is provided to reduce a whole calculation amount by verifying validity about electronic signature through a secret key and a public key about signer. An electronic signature is performed by using bilinear mapping. A secret key about signer is generated(S110). A public key about the signer is generated by using an adding group generator about the bilinear mapping and the secret key(S120). An electronic signature about a message is generated by using the secret key(S130). A validity of the electronic signature is verified by using the public key(S140). A system parameter is generated and is distributed(S150). |
