BCM5840, world's first single-chip Gigabit security processor, removes barriers providing efficient, wire-speed security across entire network infrastructure multi-Gigabit data rates. Broadcom's latest security processor sustains throughputs Gbps wirespeed IPsec encryption authentication, regardless packet size. BCM5840 provides breakthrough performance, until now, unavailable commercial products, thereby enabling ubiquitous wirespeed security routers, firewalls, switches accesses servers data rates full-duplex OC-48 (4.8 Gbps) using BCM5840 each direction. innovative BCM5840 sustains multi-Gigabit performance 3DES-CBC HMAC-SHA-1 HMAC-MD5 IPsec processing. unprecedented performance levels BCM5840 quickening pace which Internet, form virtual private networks (VPN), replacing expensive, dedicated networks remote access corporate Intranets business-to-business transactions. Flexible enough work most applications, BCM5840 utilizes POS-PHY level interface flow-through architecture. Multiple keying mechanisms supported, allowing keys sent directly in-band with packet stored on-chip security association (SA) cache.
BCM5840's on-chip storage utilizes accelerated look-up supports many 2,048 on-chip. Packet header processing BCM5840 includes IPv4 header checksum handling mutable fields associated with checksum calculation. BCM5840 optimized function IPsec coprocessor that off-loads computationally demanding cryptographic operations host protocol processor. typical application might utilize custom ASIC network processor unit (NPU) receive outbound cleartext packets, perform Security Policy Database (SPD) lookup, insert security headers, access keys from security association database (SAD), send encapsulated packets along with keys BCM5840 encryption, receive encrypted packets from BCM5840 update needed. inbound packets, ASIC would lookup security association associated vectors, send packet keys BCM5840 decryption, receive decrypted packets back, perform decapsulation cleartext packets, update SAD, verify that processing consistent with SPD, return successfully processed packets system.
