NIST selected the ASCON family of cryptographic primitives for standardization in February 2023 as the final step in the Lightweight Cryptography Competition. The ASCON submission to the competition provided Authenticated Encryption with Associated Data (AEAD), hashing, and Extensible Output Function (XOF) modes. Real world cryptography systems often need more than packet encryption and simple hashing. Keyed message authentication, key derivation, cryptographically secure pseudorandom number generation (CSPRNG), password hashing, and encryption of sensitive values in memory are also important. This paper defines additional modes that can be deployed on top of ASCON based on proven designs from the literature.
