PURPOSE: A blind signature method of an electronic commerce system or the electronic election system using euclidean algorithm without the necessity of random number generator is provided. CONSTITUTION: A user who wants to receive a signature generates a, b, X and Y using euclidean algorithm other than a message to be signed(S501). A hiding information C is calculated by using the signer's public key and the a, b generated at the step S501(S502). The hiding information C is transmitted to the signer(S503). The signer generates a signature sentence S' using his secret key(S504). The signer transmits the signature sentence S' to the user(S505). The user calculates a final blind signature S by means of the signature sentence S' transmitted from the signer and the secret information X, Y generated by him(S506).
