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.
