One-key Double-Sum MAC with Beyond-Birthday Security


MACs (Message Authentication Codes) are widely adopted in communication systems to ensure data integrity and data origin authentication, e.g. CBC-MACs in the ISO standard 9797-1. However, all the current designs either suffer from birthday attacks or require long key sizes. In this paper, we focus on designing beyond-birthday-bound MAC modes with a single… (More)
