Authentication is an important security measure for multicast applications, providing receivers with confidence that the packets they receive are valid. Simply signing every multi...
Motivated by privacy issues associated with dissemination of signed digital certificates, we define a new type of signature scheme called a `Universal Designated-Verifier Signatur...

This paper investigates some modular powering functions suitable for cryptography. It is well known that the Rabin encryption function is a 4-to-1 mapping and breaking its one-wayn...
Time Capsule Signature, first formalized by Dodis and Yum in Financial Cryptography 2005, is a digital signature scheme which allows a signature to bear a (future) time t so that t...

Standard signature schemes are usually designed only to achieve weak unforgeability – i.e. preventing forgery of signatures on new messages not previously signed. However, most s...
