TGV INTRODUCES SOFTWARE TO MAKE TCP/IP NETWORKS SECURE

TGV's Secure/IP Protects Against Unauthorized Network Access
First Step Toward Developing an Overall Security Framework

SANTA CRUZ, Calif., October 31, 1994 - TGV, Inc., the leading supplier of
TCP/IP products for the enterprise, today announced Secure/IP, a software
solution designed to make TCP/IP networks secure. In this initial release,
Secure/IP controls user access, or authentication. Future releases will
build on this framework and address other aspects of network security.
Secure/IP is a token-based software product that prevents unauthorized
user access to TCP/IP networks. Secure/IP replaces typical passwords,
which can be captured and used for unauthorized network access, with
one-time passwords, which are useless in the hands of others. According to
James Harrison of the META Group, a market research firm, "A major concern
for users implementing an enterprise-wide networking strategy is security.
Today, token-based security is the most robust user authentication for
networks available. It is fast becoming a critical component of the
enterprise security architecture and in defining a framework and
infrastructure from which to build security into the network."

Secure/IP Protects Against Unauthorized Network Users

Secure/IP protects TCP/IP networks by authenticating the network user
without exposing a password to intruders. User passwords are typically
transmitted in clear text, making them vulnerable to theft and subsequent
use. With Secure/IP users are authenticated based on two factors: a device
the user possesses, called a token, and a one-time password which is
generated by the token. One-time passwords are useless if captured, since
they combine both a personal identifier, like the PIN used with ATM cards,
and the token itself. Secure/IP supports a variety of tokens, including
Security Dynamics' SecurID, Digital Pathway's SecureNet, and Bellcore's
S/KEY software-only token.

Invaluable for Remote Network Access

Secure/IP is invaluable in WANs, over dial-up links, and, in particular, on
the Internet where electronic eavesdropping for passwords is more
prevalent. The growth in mobile computing means more and more network
users are connecting to the enterprise network from afar, increasing the
risks associated with traditional password-only authentication. "Our
customers' largest concern is the lack of security in their TCP/IP
networks," said Craig Conway, President and CEO of TGV. "With Secure/IP
we're taking the lead in making these networks more secure."

Network Security Always Foremost at TGV

Secure/IP complements the extensive security features already built into
the company's MultiNet family of TCP/IP networking software products.
MultiNet includes the Kerberos user authentication technology developed at
MIT as well as other security features for mission-critical
internetworking within the enterprise. "Kerberos has proven reliable and
safe in the more traditional bounded networks," said Conway. "However, as
the bounds of the enterprise spread with the growing number of remote
users, Secure/IP provides the same high level of network security for
TCP/IP users on the road."

Network Security Simplified for Administrators and Users

By supporting a variety of tokens, Secure/IP provides network
administrators the freedom to choose which token best meets the needs of
each user. All types of tokens are managed with a single management
utility, and Secure/IP has system-wide defaults plus per-user flexibility
for determining which method to use. For the user, Secure/IP can also
grant Kerberos keys, further reducing the overhead of implementing secure
user authentication for a MultiNet network.

Pricing and Availability

Secure/IP software will initially be available for MultiNet users on
Digital Equipment Corp.'s OpenVMS VAX and Alpha AXP computers. The
Secure/IP client software will be included in MultiNet for Windows, the
mission-critical TCP/IP implementation for Windows 3.1 and later that will
ship in the first quarter of 1995. Pricing for Secure/IP on OpenVMS
platforms ranges from $1,000 to $12,000, depending on the number of users
served.

TGV, Inc.

TGV, Inc. is the leading independent provider of industrial-strength TCP/IP
internetworking software. TGV created the first TCP/IP software for
Digital Equipment Corp. VAX computers, and is a standard in that market
today. The company's scalable software was engineered to be easily
portable across platforms and operating systems essential to the
enterprise. TGV's customers, at some 15,000 installations worldwide,
include AT&T, Boeing, Chevron, Electronic Data Systems, Goldman Sachs,
