In this paper, the authors propose a simple IPSec protocol stack for micro server. The authors proposed an implementation of IPSec protocol stack which is constructed by Encapsulating Security Payload (ESP) protocol with Advanced Encryption Security (AES) encryption scheme, whereas authentication using MD5 algorithm is optional. Researchers have focused on creating a small system composed of sensors and a micro server where it has a small sized memory, multi-function, low cost, but without security consideration. The security problem in the micro server is a challenging task because of the very limited flash memory.
