In 2023, NIST has selected Ascon as the new standard for lightweight cryptography. The Ascon v1.2 family provides authenticated encryption, hash functions, and extendable output functions, all using the same Ascon permutation. The main use case of Ascon is to provide efficient cryptographic ...
In this paper, we enrich the functionality one can get out of Ascon's permutation by providing efficient Pseudorandom Functions (PRFs), a Message Authentication Code (MAC) and a fast short-input PRF for messages up to 128 bits.年份: 2021 ...
