Abstract: An identification scheme, a digital signature scheme giving message recovery, and a digital signature scheme with appendix are disclosed. In processing and transmitting information, a transmitting counterpart of a transmission message is confirmed. The unauthorized modification of the message is confirmed and transmitting behavior is detected, thereby providing the reliable information service.

Abstract: The method involves the sender (A) selecting a first arbitrary number (r1) and calculating a remainder x from a preset formula to produce an identification number h(x,IDA) which is transmitted to the receiver (B). The sender also selects second and third random numbers (r2,r3) and calculates further remainders (r4,r5) using predetermined formulae. A further calculation is then carried out using the initially generated identification and the new remainders to provide further remainders (y1,y2). The coding produced is passed to the receiver. The receiver can then validate and recover the message received, using further agreed formulae.
