SECURE DIGITAL SIGNATURE SCHEMES

원문 (중국어)

A computer-implemented method, according to one approach, includes: computing a first cryptographic term in response to receiving a session request from a user. The first cryptographic term is split into an initial portion and a remainder portion, where the remainder portion includes at least one bit. The initial portion of the first cryptographic term is sent to the user, and two or more different potential second cryptographic terms are received from the user. The at least one bit in the remainder portion is used to determine a correct one of the potential second cryptographic terms. Moreover, the correct one of the potential second cryptographic terms is used to compute a third cryptographic term. Furthermore, the third cryptographic term is sent to the user.
