Design and Implementation of the Ipsec-based Security System

Ipsec is a standard protocol to offer Internet information security service. Recently Ipsec is implemented through out the world on the base of various operating systems. Through the inter-operability test among multiple independent implemented devices, it is now the mandatory function of Internet equipment. Ipsec adds two headers (i.e.,AH & ESP) and protocol to the legacy IP packet so therefore, Ipsec offers not only internet security service such as internet secure communication, and authentication service but also the safe key exchange and anti-replay attack mechanism. In this paper, we propose the design and implementation of C-ISCAP, which is Ipsec based Internet information security system and also we will show the data of performance measurement.
