Abstract
By applying the concept of VRES (Verifiable and Recoverable Encrypted Signature), a kind of RSA-based fair exchange protocols try to provide security mechanism on information delivery assurance. However, due to incomplete verification on VRES, RSA extended modulus attacks addressed in this paper can be launched on those protocols successfully, causing failure on fairness of exchange. The RSA-DEMCA algorithm is proposed, achieving complete verifications on VRES without sensible information leakage. Security analysis on RSA-DEMCA is also addressed.
