Abstract: This article researches the use of AES cipher mechanism within IPSec encapsulating security payload (ESP). AES algorithm is a symmetrical block cipher algorithm; it can select many operation modes to work. In building IPSec VPN based on AES cipher mechanism, it notices some problems of using CBC and CTR operation modes mainly are discussed. At the same time, it analyzes the excellent performances of AES algorithm.
