ZETA: Towards Tagless Authenticated Encryption

Anindya Shankar Bhandari and Dipanwita Roy Chowdhury

Abstract

Tag-based message authentication is a popular cryptographic technique to digitally sign messages. However, for short messages, it often incurs additional costs due to large tags. In this paper, we propose a new scheme that achieves tagless message authentication. The scheme leverages a trade-off between character support and complexity of forgery to provide information security and authenticity.

Note: Minor changes to terminology.
