LAS VEGAS--(BUSINESS WIRE)--May 11, 2004

Collaboration results in highly scalable and cost-effective

security management architecture for wide range of networking devices

and PC-based security applications

nCipher plc (LSE: NCH), a leading provider of IT cryptographic security, today announced that it is collaborating with Broadcom Corporation (Nasdaq: BRCM) to improve the way security is deployed and managed in consumer and business devices such as laptop computers and network equipment. As an extension to its established strategic partnership with Broadcom, nCipher will provide security management products to support Broadcom's BroadSAFE(TM) security initiative which embeds strong identity and encryption capabilities within a wide range of Broadcom's networking semiconductor product lines including IP phones, Gigabit Ethernet controllers, network switches, broadband and security processors (see separate Broadcom press release today).

In addressing both client security and management infrastructure together, Broadcom and nCipher's joint solution will build trust across large scale networks by dramatically reducing the threat of direct attack to isolated and inherently unprotected devices. This approach removes the need for expensive client security add-ons such as USB tokens or smart cards, and will significantly reduce administration costs through the automation of many tasks associated with security provisioning and management. As a result, for the first time the potential exists for tamper-resistant security to become a ubiquitous component of even the most commoditized devices(TM).

The jointly-engineered solution has two fundamental goals:

-- To enable highly cost sensitive equipment such as telephones,

laptop computers and networking devices to securely prove

their own integrity, manage user identities and ensure

confidentiality, enforcing unified security policies in an

auditable way.

-- To establish a security management infrastructure that

coordinates and automates the installation, enrolment,

provisioning and future deactivation of distributed client

devices to enable roaming users and device mobility, emergency

recovery and network reconfiguration.

These goals will be achieved through the combination of Broadcom's BroadSAFE enabled semiconductor components and new security management products from nCipher that will build upon the company's highly scalable 'Security World' key management framework and range of hardware security products that has been independently validated to the Federal Information Processing Standard FIPS 140-2.

"Broadcom is uniquely placed to address the growing need for improved security in mainstream broadband equipment right out to the edge of the network, but as we all know, effective security is rarely provided by a point solution," said Dr. Ford Tamer, Group Vice President, Networking Infrastructure Group, at Broadcom. "nCipher and Broadcom have defined an end-to-end approach that leverages the powerful capabilities of nCipher's industry proven and FIPS validated key management technology and this provides the perfect complement to our BroadSAFE strategy. We are excited by this important evolution of our long-standing partnership with nCipher."

"The successful deployment of new security approaches such as digital rights management, strong authentication and secure internal communications relies on a coordinated approach to client security in order to achieve scalability and avoid spiraling administration costs," said Alex van Someren, president and chief executive at nCipher. "By licensing important enabling technology to Broadcom as part of their BroadSAFE program and by joining the Trusted Computing Group (TCG), nCipher has made a strong commitment to delivering a solution that enables the kind of hardware-based cryptographic security on client devices and consumer products that has traditionally only been deployed on high-end servers and mainframes."

nCipher's future security management products will be available in various configurations to suit a range of both embedded and standalone applications, further details will be released in due course.
