Design of a system to support security communication between a Web proxy and a CGI program based on PKI

Abstract

This paper discusses the design of a system to support security communications between a Web browser and a CGI program using PKI (public key infrastructure). TLS (transport layer security) supports security communications between a Web browser and a Web server, but this system supports security communications between a Web server and a CGI program as well as between a Web browser and a Web server. This system uses GSS (generic security service) API to communicate with PKI, and offers a Web user a Web proxy, and offers three library functions for CGI applications related to security. This makes it easier for a CGI developer to write a CGI program.
