Sycon: a new milestone in designing ASCON-like permutations [PDF]

Journal of Cryptographic Engineering, 2021
ASCON is one of the elegant designs of authenticated encryption with associated data (AEAD) that was selected as the first choice for lightweight applications in the CAESAR competition, which also has been submitted to NIST lightweight cryptography standardization. ASCON has been in the literature for a while; however, there has been no successful AEAD

Ascon v1.2: Lightweight Authenticated Encryption and Hashing [PDF]

Journal of Cryptology, 2021
AbstractAuthenticated encryption satisfies the basic need for authenticity and confidentiality in our information infrastructure. In this paper, we provide the specification ofAscon-128 andAscon-128a. Both authenticated encryption algorithms provide efficient authenticated encryption on resource-constrained devices and on high-end CPUs.
