Abstract |
E-mail is considered as one of the most important and most frequently used internet services. For privacy and security reasons, it is desirable that e-mail protocol provides deniability. Deniability ensures that a receiver can identify the source of a received message while a third party cannot. If deniability is provided in e-mail protocol, the third party would not be able to distinguish who created the e-mail between sender and receiver. However, current secure e-mail protocols such as PGP and S/MIME use digital signature which does not provide deniability. In this paper, I propose a new identity-based designated verifier signature scheme which can be applied to deniability in e-mail protocol. |
