ECC-based new designated verifier signature scheme

To avoid the problem of transferability of verification right,the way to ensure that only those who had designated verifier's private keys could verify the validity of signatures was researched.An ECC-based new designated verifier signature scheme was proposed,which could avoid the limitation of delegatability.It was supposed that whether a designated verifier signature possess non-delegatability could be judged by the format of the verifying equation.A general format was also proposed with which the designated verifier signature schemes could avoid the limitation of delegatability.Based on the idea above,a modification of the SKM scheme was made.
