Large corporate virtual private networks (VPNs) demand high-performance encryption power. The PCI-based IPS200A and IPS500A CryptoNetX Accelerator Adapters work to eliminate security bottlenecks in network infrastructure. The boards' sustained encrypted throughput is 200 Mbits/s and 500 Mbits/s, respectively. Both support 256-bit AES keys. The cards, crafted by Broadcom, provide bulk symmetric encryption algorithms, hash algorithms, and keyed authentication algorithms, plus IPsec bulk payload processing for all AES modes. IPS200A and 1PS500A samples cost $603 and $958, respectively.
