Abstract

An compacted representative signature is a string that persuade the checker to believe that, for all 1 ≤ i ≤ n, the i-th representative signer approved a piece of information. The loss of clandestine keys threatens a security system. We come up with the idea of Identity-Based Key-Preserved Compacted Representative Signature (IBKPCRS) in which representative signing keys vary over time. The usage of IBKPCRS is to meet the key-revealing challenge. In the IBKPCRS system, the user sets his telephone number or other overt string as his public key. We give the IBKPCRS scheme as a teaching case of cryptography.
