RSA Conference 2024 · Track Session
This talk delves into the **Ascon** cryptographic primitive, specifically focusing on its recently developed Message Authentication Code (MAC) and Pseudo-Random Function (PRF) constructions. Ascon is a lightweight cryptographic algorithm that was selected by the U.S. National Institute of Standards and Technology (NIST) for standardization, addressing the critical need for robust yet efficient security solutions in the burgeoning Internet of Things (IoT) landscape. Presented by one of the co-authors of the work, this session highlights how Ascon's permutation-based design, originally conceived for authenticated encryption and hashing, has been extended to provide highly efficient MAC and PRF capabilities.
