Encryption Security

Business Editors/High-Tech Writers

FAIRFAX, Va.--(BUSINESS WIRE)--Aug. 25, 2003--

Wearable Computing and Trusted Security Capabilities Target
Government, Military, Intelligence and Commercial Sectors

Xybernaut(R)Corporation (NASDAQ:XYBR) and Cryptek, Inc. today
announced a marketing and integration agreement under which Xybernaut
wearable/mobile computers will be integrated with the Cryptek
government certified network security solution DiamondTEK(TM).
Under the terms of the agreement, both companies are already
working together to integrate the Xybernaut Mobile Assistant(R)V
(MA(R)V) and Atigo(TM) with the Cryptek DiamondTEK(TM) family of
government certified network security solutions. The integration
brings unique government certified network security capabilities to
existing and future Xybernaut users. These enhanced security
capabilities include:

-- IPSec Encryption

-- Firewall access controls

-- Common Criteria EAL-4 certification as a VPN, firewall and
network management solution

-- FIPS 140 certification

-- Creation of strong communities of interest over shared
networks

-- Dynamic user selectable role-based policies

-- Full central management of all security policies, updates and
audits

Initial efforts focus on government customers where the
requirement for government certified network security is demanded
through pre-authorized policies such as the National Security
Telecommunications and Information Systems Security (NSTISSP No. 11).
Under NSTISSP No. 11, all commercial off the shelf (COTS) information
assurance (IA) and IA-enabled products must meet government
certification standards under International Common Criteria or NIST
Federal Information Processing Standards (FIPS). Cryptek DiamondTEK
network security solutions have been certified under both the Common
Criteria and FIPS standards.
"Mobile computing over wireless LAN, WAN and satellite is clearly
a growing market," said David Gross, president and CEO, Cryptek Inc.
"One of the key factors limiting growth in this market is security. In
combining our proven government certified network security solutions
with Xybernaut MA V and Atigo wearable computers, both Xybernaut and
Cryptek are able to offer enhanced security and functionality to best
meet government and commercial customer needs."
"Trusted information assurance is an area in which Cryptek has
established itself as a market leader. Whether users find themselves
performing secure government tasks, military or intelligence missions
or commercial activities, trusted computing environments are
critical," stated Steven A. Newman, president of Xybernaut. "Xybernaut
and Cryptek are now developing integrated solutions to boost security,
improve identity assurance and enhance access-to and management of
enterprise knowledge."
In addition to providing government certified network security for
MA V and Atigo product families, DiamondTEK has a unique dynamic
role-based capability which allows polices to be set based on who the
user is, which device they are accessing and what specific
policy/community of interest they are requesting access too. This
allows a single shared network to be separated into different
"need-to-share/need-to-know" secure communities of interest.
