SIGNATURE GENERATION TERMINAL, SIGNATURE VERIFICATION TERMINAL AND METHOD FOR VERIFYING THE HYBRID-TYPE QUANTUM SIGNATURE TAG USING THE TERMINAL

摘要

PURPOSE: A signature generation terminal, a signature verification terminal and a hybrid type bilateral signature tag verification method using the same are provided to allow a selection degree of freedom of a signature system in both transmission terminal and reception terminal. CONSTITUTION: A transmission terminal(100) generates a signature value with a tag related to a message using a bilateral state having a random initial condition. A reception terminal(200) verifies the signature value transmitted from the transmission terminal. The transmission terminal includes a random number generation unit(110) and a signature generation unit(120). The random number generation unit generates a common random number using a first secret key sharing with the reception terminal having the same size of the first secret key. The signature generation unit generates a tag value using a message requiring a signature and a second secrete key for generating a signature value and generates a signature value by encoding a tag value with a common random number.
