WebOct 25, 2024 · Ascon family is one of the finalists of the National Institute of Standards and Technology (NIST) lightweight cryptography standardization process. The family includes three Authenticated Encryption with Associated Data (AEAD) schemes: Ascon-128 (primary), Ascon-128a, and Ascon-80pq. WebAug 1, 2024 · ASCON is an authenticated cipher, the CAESAR competition winner under lightweight use case portfolio, in February 2024. The use of 128-bit random nonce as part of the input state makes the cipher resistant against classical cryptanalysis techniques such as differential cryptanalysis, linear cryptanalysis, and variants.
