With the rapid development of authenticated encryption (AE) algorithms in recent years, especially after the CAESAR (Competition for Authenticated Encryption: Security, Applicability and Robustness) competition was launched, a large number of excellent authenticated encryption algorithms have emerged, making the analysis of authenticated encryption algorithms a hot research issue. The CAESAR competition was launched under the sponsorship of IACR in 2014, aiming to collect excellent authentication encryption algorithms from all over the world. SAEAES is a relatively excellent authentication encryption algorithm in the CAESAR competition. In this paper, the sponge structure of SAEAES is improved by introducing the MD (Merkle Damgard) iterative structure. At the same time, in order to improve the ability to resist collision attacks, fixed point attacks and cluster attacks, the MD iterative structure itself is also improved.
