Among these proposed schemes, the agreement between the compiler maker and compiler severs is confirmed by two distinct signatures. It is inefficient to adopt two distinct signatures to confirm the same agreement. To overcome this inefficiency, our first scheme is proposed. In these proposed schemes and our scheme, the used compiler agents’ public keys should be certificated and maintained by verifiers. If verifiers only keep the compiler makers’ public key, it is more convenient. So an anonymous proxy automatic signature scheme with compiler agents is proposed. In the new scheme, the compiler agents are anonymous and verifiers do not need to store compiler agents’ public key. Moreover, verifiers can authenticate the source of received executable problems and detect compiler agents’ deviation in advance. Our schemes are suitable for adopting any discrete logarithm based signature schemes. Our scheme has provides strong moderator’s judgment to detect of virus infection sources.
