Most of the existing ID-based designated verifier proxy signature schemes are implemented with pairings. The computation of parings is still much more expensive than the common modular multiplications and exponentiations. To obtain better efficiency, we construct an efficient ID-based DVPS scheme without pairings. The scheme is designed based on the hardness of the discrete logarithm problems. It is proven secure against adaptively chosen message attacks, in the random oracle model.

By cryptanalysis of a strong designated-verifier proxy signature scheme, it is found that this scheme has security leaks: original signer can forge the proxy signers valid proxy signature for any message; not only the designated-verifier but also proxy signer can verify the signature and proxy signer can misuse it. An improvement is given, and the security analysis shows that it can resist the spiteful forgery attacks by original signer and prevent the misuse of proxy signature by proxy signer.
