AUTHENTICATED ENCRYPTION FOR DIGITAL SIGNATURES WITH MESSAGE RECOVERY

摘要

A framework is proposed for authenticated encryption for digital signatures with message recovery whereby authentication is achieved without a redundancy requirement. The Elliptic Curve Pintsov-Vanstone Signature scheme is modified through the use of authenticated encryption, thereby enabling authentication using a message authentication code (1028). The authenticated encryption may be performed within a single function or as two separate functions. The authenticated encryption may also be applied to associated data in the message (104) to be signed.
