ABSTRACT:
A network system providing integration. The network system includes a client computer, a server, a server-side cryptographic function, a PKI-Bridge, a remote access switch, a client-side cryptographic function, a dial-up client, and a custom script dynamically linked library. The server-side cryptographic function is located on the server and provides cryptographic services. The PKI-Bridge provides an interface between the server and the server-side cryptographic function. The remote access switch provides an interface between the client computer and the server. The client-side cryptographic function is located on the client computer and provides cryptographic services. The dial-up client provides dial-up services to access the remote access switch. The custom script dynamically linked library provides an interface between the dial-up client and the client-side cryptographic function.
