5802-DS03-405-R

IETF IPSEC COMPLIANT ACCELERATION

•

3DES CBC encryption and decryption in accordance with FIPS 46-3 and FIPS 81.

•

HMAC-MD5-96 and HMAC-SHA1-96 authentication in accordance with RFC2403, RFC2404 and FIPS 180-1.

Automatic generation of MD5/SHA1 padding.

•

Single-pass encryption and authentication via pipelined application of algorithms over payload in accordance with

RFC2402 and RFC2406.

•

Automatic sequencing of encryption and authentication: Encrypt first for outbound packets, authenticate first for

inbound packets in accordance with RFC2401.

IETF IKE

•

768-bit and 1024-bit Diffie-Hellman key generations for IKE handshake according to RFC2409

•

512-bit, 768-bit and 1024-bit RSA signing and verification for IKE handshake

•

1024-bit DSA signing and verification for IKE handshake according to FIPS 186-2

•

True random number generation for IKE keys using on-chip random number generator

SECURE SOCKET LAYER (SSL) V 3.0, TRANSPORT LAYER SECURITY (TLS)

•

512-bit, 768-bit, and 1024-bit RSA public key and private key processing

•

512-bit, 768-bit, and 1024-bit Diffe-Hellman session key generation

•

DES and Triple-DES bulk encryption capability

•

1024-bit DSA signing and verification

•

HMAC-MD5/SHA1 bulk authentication according to RFC2104

STREAMLINED, FLEXIBLE SOFTWARE COMMAND AND PACKET INTERFACE

•

Flexible command interface allows exchange of multiple packets or public key setups with one PCI write

•

Zero latency command buffer switching via double-buffered master command register

•

Support for big and little endian environments

•

Host CPU intervention not required between packets or between key setups

•

Intelligent, autonomous DMA descriptor based interface to minimize software load

•

Scatter/Gather support to eliminate packet data or key setup data copying

–handles fragmented data directly

•

Support for any number of IPsec security association contexts, limited only by system memory

ADDITIONAL PERFORMANCE ENHANCING FEATURES

•

Latency-tolerant design optimized for shared PCI bus environments. The BCM5802 leverages PCI burst mode access

capability, up to a maximal burst size of 64 bytes.

•

Aggressive pre-fetch of command and packet data.

•

Full performance is maintained independent of any reasonable PCI latency.

ADVANCED TESTABILITY FEATURES

•

100% testability of on-chip RAM cells via BIST circuitry

•

JTAG boundary scan for board-level testing
