| Abstract: | As more and more electronic transactions are being conducted on the IN TERNET, fair exchange protocol is becoming more and more important. Verifiable e ncryption is introduced as a primitive that can be used to build extremely effic ient fair exchange protocols where the items exchanged represent digital signat ures. In this paper, new verifiable encryption schemes are presented, and based on this scheme, a blinded verifiable encryption is presented. They are advantage ous over previous schemes in that they are more efficient and practical. |
