Business/Technology Editors

DUBLIN, Ireland--(BUSINESS WIRE)--Feb. 20, 2001

Inventor of PGP joins leading encryption company, Hush

Communications, to accelerate adoption of mass-market cryptography

Hush Communications Corporation (www.hush.com) today announced the appointment of Philip R. Zimmermann as a Chief Cryptographer for the Company. Zimmermann has been asked to lead Hush's efforts to fully integrate support for the OpenPGP standard into Hush's core technology by President and Chief Executive Officer, Jon Matonis, and Chief Technology Officer, David Bowman.

Hush Communications is the leading global provider of managed security solutions and encrypted key serving technology. Hush offers its clients and end users access to its worldwide key server network, and manages both the users' public and private keys allowing for unprecedented roaming capability, end-to-end security, and completely transparent key management.

Zimmermann is the creator of Pretty Good Privacy (PGP), the first encrypted email program, and the founder of PGP Inc. Zimmermann comes to Hush with more than 20 years' experience as a software engineer, specializing in cryptography and data security, data communications, and real-time embedded systems. In his new role, Zimmermann will lead Hush's completion of the company's technology integration with industry standards as well as offering input in the general cryptography arena. PGP is the current de facto standard for encrypted email and as such, Zimmermann will bring Hush's system closer to interoperability with a proven and trusted cryptographic system.

Zimmermann stated, "For the past decade PGP has been the gold standard for email encryption but we've always had trouble expanding beyond the power users because of ease of use problems. The OpenPGP standard will be well served by Hush's fresh approach to ease of use and its roaming capability. Further, Hush has a consistent track record of publishing its source code."

Jon Matonis, President and CEO of Hush Communications stated, "Phil's contribution to the field of cryptography and his commitment to privacy are unrivaled. At Hush, we've committed our resources and energy to the mainstream corporate and consumer adoption of strong encryption. Between the sophistication of industry standards and the elegance and usability of Hush's core technology, we surpass any other available solution on the market."

The Hush Key Server Network will support the secure storage and delivery of public and private keys in a format independent manner, including the OpenPGP format. OpenPGP is an Internet Engineering Task Force (IETF- www.ietf.org) monitored standard for the encryption of information created by Zimmermann.

Zimmermann joins Hush Communications from Network Associates Inc. [NASDAQ: NETA] where he served as a senior fellow. He has been an active part of shaping US public policy regarding encryption, having been called to testify by the U.S. Senate in 1996. He has received numerous technical and humanitarian awards for his pioneering work in cryptography. In 2000, Info World named Zimmermann one of the Top 10 Innovators in E-business. In 1999, he received the Louis Brandeis Award from Privacy International, in 1998 a Lifetime Achievement Award from Secure Computing Magazine, and in 1996 the Norbert Wiener Award from Computer Professionals for Social Responsibility for promoting the responsible use of technology.

Zimmermann received his bachelor's degree in computer science from Florida Atlantic University in 1978. He is a member of the International Association of Cryptologic Research, the Association for Computing Machinery, the League for Programming Freedom, and Computer Professionals for Social Responsibility. He serves on the Board of Directors for GlobalNet International. To learn more about Philip R.
