Artemia: A Family of Provably Secure Authenticated Encryption Schemes

Authenticated encryption schemes establish both privacy and authenticity. this paper specifies a family of the dedicated authenticated encryption schemes, artemia. it is an online nonce-based authenticated encryption scheme which supports the associated data. artemia uses the permutation based mode, jhae, that is provably secure in the ideal permutation model. the scheme does not require the inverse of the permutation in the decryption function, which causes the resource efficiency. artemia permutations have an efficient and a simple structure and are provably secure against the differential and linear cryptanalysis. in the permutations, mds recursive layers are used that can be easily implemented in both software and hardware.
