Abstract:
This article describes the specification and analysis of the CiliPadi family of lightweight authenticated encryption v1.2. An earlier version, dubbed v1.0, was accepted as one of the Round 1 candidates in the US NIST lightweight cryptography project. CiliPadi is designed based on the Sponge construction which is also used in the SHA-3 hash function. CiliPadi supports 128 and 256-bit keys and is offered in four variants or flavours. The flavours differ in the length of tag, message block and the number of rounds of the internal permutation.
Keywords: authenticated encryption; sponge construction; lightweight cryptography; symmetric encryption; generalized Feistel network
