Broadcom and Microsoft Work Together to Bring High-Speed Security to

E-Commerce Transactions

Broadcom Corporation (Nasdaq: BRCM), the leading provider of integrated circuits enabling high speed broadband communications, today announced the Broadcom(R) BCM5820, the world's highest performance, integrated processor chip for accelerating secure E-Commerce transactions.

Broadcom has worked closely with Microsoft to enable the BCM5820 to transparently accelerate E-Commerce transactions for Internet Information Server/Windows 2000, today's leading secure E-Commerce Web server platform. A live demonstration can be found in Booth 21 at the Microsoft Partner Solutions Center at NetWorld + Interop 2000 Atlanta.

The BCM5820 CryptoNET(TM) E-Commerce Processor, the newest member of Broadcom's CryptoNET security processor family, delivers 15 times the performance of today's software-based solutions in a highly integrated, single-chip solution. Sustaining up to 1,000 Public Key (1024 bit RSA) transactions per second, the BCM5820 virtually eliminates the cryptography bottleneck in high performance SSL-enabled Web servers, thus freeing up the host CPU's resources for other Web serving tasks.

"Broadcom is eliminating the trade-off between Web-browsing efficiency and the security of information in E-Commerce transactions over the Internet," said Suresh Krishna, Broadcom's Senior Director of the Security Business Unit. "Broadcom is addressing concerns of doing business of any kind over the Internet by deploying inexpensive E-Commerce processors that greatly speed up secure Web transactions."

The success of the Internet as a tool for E-Commerce requires the ability to protect personal and proprietary information while using the World Wide Web to conduct business and banking transactions, communicate via email, and transfer information. SSL (Secure Socket Layer) is the de facto standard for secure Web browsing and relies heavily on compute-intensive RSA transactions. Typically, the host CPU performs these operations, consuming all or most of its processing bandwidth. The BCM5820 performs all the security specific processing required for SSL at rates up to 15 times faster than host-based software solutions, thus freeing up the host CPU for mission critical applications.

The BCM5820 E-Commerce Processor is the first single-chip solution to provide all the cryptography and peripheral support necessary for high-performance SSL and Internet Key Exchange (IKE) encrypted connections. The BCM5820 reduces all the functions of a competitive board-level solution into a single, highly integrated 256-pin TBGA chip. The BCM5820 also accelerates the ARCFOUR, 3DES and DES symmetric algorithms and supports MD-5, SHA-1, and random number generation through a 32/64 bit, 33/66 MHz PCI 2.2 interface. The BCM5820 provides scalability to many thousands of RSA transactions per second with the ability to add multiple chips on a single PCI card and multiple PCI cards in a system. E-Commerce Web servers, Web switches, load balancers and content-aware routers will see a dramatic increase in SSL and IKE performance with the BCM5820.

Broadcom's highly integrated chip requires no external components or memory and is software-compatible with Broadcom's other CryptoNET(TM) chips, the BCM5805 and BCM5801, for network security.

The BCM5820 is packaged in a 256-pin TBGA and will sample to lead customers in October, with production quantities available in November. Sample quantity pricing is $200.
