Abstract: This paper presents an efficient blind signature scheme under which information can be hidden in the signature and uncovered later for security purposes. When it is applied to an untraceable electronic cash system, cash owners are able to claim and identify lost cash; when applied to an anonymous electronic voting protocol, no election results are revealed until the entire voting process is finished. The additional computation for the proposed scheme, as compared with typical blind signatures, consists of just two hashing operations.

Key Words and Phrases: Anonymous electronic voting, blind signature, Internet security, privacy, untraceable electronic cash.
