Research and Implementation of IPSec in IC Payment Gateway

IPSec provides authentication and encryption mechanisms for network security. How to enhance efficiency and flexibility is one of important issues of IPSec. This article introduces the traditional solution of IPSec security, analyses the designs to deal with data packets by IPSec, and provides a solution which integrates the IPSec processing and the core processing of IP layer and, as a result, enhance the security of IC payment. Through the implementation of digital sports projects, it verifies the usability and feasibility of the IPSec design.
