Problems solved by technology

However, the conventional protocol for a remote access (RA) client (a client for creating an Internet connection) communicates the login credentials of the users in an unsecured fashion.
If a user maintains identical login credentials for RA authentication and VPN authentication, then the VPN is compromised if the user's RA credentials are stolen.
Accordingly, a VPN using a conventional VPN client is vulnerable to the extent the user's RA credentials are vulnerable.
Thus even in these situations, encrypted user ID and passwords are not necessarily protected from theft.
In fact, the user ID and password are subject to theft whenever they are communicated in clear text, whether by unscrupulous ISP employees, or others who have hacked into the ISP network.
Accordingly, RA credentials are vulnerable to compromise, potential

Embodiment Construction

[0041] Referring now to the drawings, wherein like reference numerals designate identical or corresponding parts throughout the several views.

[0042] An exemplary embodiment of the present invention is illustrated in FIG. 4. FIG. 4 shows a computer system including a client 100 running on a computer 110 having a connection to the Internet 40 through NAS 42. Platform 150 is also connected to Internet 40. Remote RADIUS server 190 is connected to platform 150 through IPSec tunnel 188. Platform 150 includes Authentication, Decryption, and Routing System 200 and Single Sign On Application Server (SSOS) 160. Computer 110 has a SECUREID 120 associated therewith.

[0043] When a user requires access to remote server 210 from computer 110, the user enters their login credentials (user ID and password) into computer 110. Client 100 encrypts the user's ID and separately encrypts the user's password prior to passing the encrypted credentials to computer 110, which then transmits the credentials o...

Abstract

A computer-implemented method and apparatus authenticates a user of a remote computer over a network. In one aspect of the present invention, an authentication challenge is received at said remote computer an authentication challenge message from an authentication server over a network, at least a portion of the network including an Internet communication link. A passcode is received at the remote computer. A response message to the authentication challenge is created, the response message including the passcode. The response message is transmitted from the remote computer to the authentication server over the network. The remote computer receives a verification message from the authentication server that the response message is verified.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of the earlier filing date of U.S. Provisional Application No. 60 / 495,131, filed Aug. 15, 2003, entitled “System, Method, Apparatus and Computer Program Product for Facilitating Digital Communications” and U.S. Provisional Application No. 60 / 581,729, filed Jun. 23, 2004, entitled “System, Method, Apparatus and Computer Program Product for Facilitating Digital Communications,” the entirety of both of which being incorporated herein by reference.FIELD OF THE INVENTION [0002] The present invention generally relates to systems and methods for providing secure digital communications over a computer network. BACKGROUND OF THE INVENTION [0003] A Virtual Private Network (VPN) is a private network created over a public network where exclusive client and host communications occur. A conventional VPN connects users or sites over a public network, usually the Internet. Virtual privacy is derived from secure tunne...
