Abstract: A new secure two-party computation problem, called secure transformation-equivalence problem, is proposed, which researches how to determine whether two transformations, defined on some finite set, are equivalent in the sense of privacy preserving. Based on additively homomorphic encryption system, a secure transformation-equivalence determination protocol is constructed. It is proved that the protocol is correct, and the protocol is secure under the semi-honest adversary model. Furthermore, the efficient of the protocol is shown.

Key words: secure multiparty computation, homomorphic encryption system, transformation-equivalence, semi-honest adversary model
