ZyTrax is pleased to make the following announcement with Hifn - one of its key technology partners.

LOS GATOS, Calif., July 10 /PRNewswire-FirstCall/ -- Network security and
flow classification market leader Hifn (Nasdaq: HIFN), announced today that
ZyTrax, Inc. has integrated Hifn security processors into its Air-Frame-100, a
high performance wireless LAN IP router that provides rugged and reliable
performance over distance for use in demanding IP network applications.
   ZyTrax's Air-Frame-100 LAN IP router provides features and services to
suit the most demanding IP network environments. The Air-Frame 100 comes
standard with an embedded Proxy server, NAT/PAT, DHCP server, Quality of
Service (QoS) capabilities, a Firewall (LockBox) as well as flexible and
powerful routing capabilities. For secure applications the standard encryption
module provides either 'on-air' security or end-to-end VPNs using IPsec.
   "The Hifn 7902 allows us to offer our customers standards based IPsec as
an alternate to the compromised WEP of 802.11," says Ron Aitchison, President
of ZyTrax, Inc. "The 7902 compression capability is also vital in the finite
radio bandwidth environment allowing us to maximize throughput. Combining all
this into a single package with modest footprint and negligible processor
overhead really makes the 7902 a no-brainer decision."
   "The Air-Frame-100 is ideally suited for demanding and secure IP network
applications including Internet and Intranet access networks," says Doug
Makishima, Hifn's vice president of marketing. "We are highly pleased that
Hifn's security processors are a part of ZyTrax's Air-Frame-100."
  The Hifn 7902 security processor used in the ZyTrax Air-Frame-100 performs
multi-algorithm encryption acceleration on a single chip, with a powerful
on-board IKE (Internet Key Exchange) processor for public key operations.
Protocols supported by Hifn security processors include IPsec, IPPCP, PPTP,
L2TP, PPP, and IKE. Algorithms that can be performed include DES, 3DES, and
ARC4 encryption, RSA, DSA, and DH public key, SHA-1 and MD5 authentication,
and LZS and MPPC compression. The processor also generates true hardware
random numbers that are an essential part of the public key infrastructure.
Symmetric and public key processing is performed concurrently to enable
low-latency performance.
