The BCM5823 Cryptonext IP security processor from Broadcom Corp. supports the 256-bit key Advanced Encryption Standard (AES) at 500Mbps, addressing the requirements of embedded firewalls, VPN appliances, VPN-enabled routers, and access devices for securing confidential e-commerce transactions and data transfers over the Internet.

The processor is available in two configurations - 500Mbps throughput supporting 400 Internet Key Exchange (IKE) sessions per second, and 200Mbps supporting 200 IKE sessions per second.

The chip supports IPsec bulk payload processing for all of the AES modes, including 128-, 192-, and 256-bit AES-CBC and AES-CTR key length support. It also accelerates ARCFOUR at 800Mbps and supports 3DES and DES symmetric algorithms, MD-5, SHA-1 hash algorithms, and random number generation through its 64-bit 33MHz/66MHz PCI 2.2 interface.

The 256-pin PBGA device is claimed by the company to require no external components or memory, and has a power consumption of 1.3W at 500Mbps or 1.1W at 200Mbps.

It comes with an embedded software development kit compatible with the company's other CryptoNetX security chips, enabling manufacturers to build a range of security solutions using one software platform. The kit includes a reference design and a cryptographic software library, supporting BSD, Linux, and VxWorks OS.
