Hifn announced its next-generation FlowThrough security processor designed for IP storage networking applications. The HIPP III 4450 is said to offer simultaneous support for multiple security protocols, and encryption and authentication algorithms. The processor aims to address the "data in flight" security requirements for IP storage protocols, including iSCSI, FCIP, iFCP and NAS. It is designed for integration into iSCSI host bus adapters, target bus adapters, storage switches and storage arrays.

According to Hifn, the FlowThrough architecture accelerates the entire data path, and allows the processor to be interfaced as a "bump-in-the wire" adjacent to TCP offload engines, storage processors or Gigabit Ethernet media-access controllers.

The product also has IPv4 and IPv6 support and offers IPcomp LZS compression and MACsec processing, in addition to IPsec. The 4450 incorporates Ethernet and memory interfaces including SGMII, Serdes, RGMII, RTBI and DDR2 SDRAM.

The addition of wire-speed IPcomp compression capability increases the value of this solution to the OEM," said Bob Doud, security product line director at Hifn. "Compression can eliminate the packet overhead associated with security protocols, and also increases throughput and reduces latency due to the reduction in traffic over the network," said Doud.

Hifn claims that the 4450 is the first security processor in the market to provide in-line support for the IEEE 802.1ae "MACsec" protocol. This is a new link-layer security protocol that enables endpoint authentication and protects Ethernet traffic over the LAN with encryption and integrity protection.

The 4450 allows glueless interfacing to Ethernet PHYs and host MAC devices. The new Ethernet interface options include RMII, RTBI, GMII, TBI, Serdes and SGMII. A single DDR2 ECC SDRAM interface is said to allow running on-chip IKE as well as supporting large numbers of secure tunnels.

The device offers cryptographic algorithms, including: DES, 3DES, AES-CBC, AES-CTR, AES-CCM, AES-GCM, SHA-1, SHA-256, MD5 and AES-XCBC-MAC. An on-chip public key engine supports Diffie-Hellman, RSA and DSA operations at up to 8,192bit modulus size.

The product supports two full-duplex Gigabit Ethernet ports, and delivers 4Gbps simultaneous protocol processing for large packets and 1.2M packets per second for small packets. Up to 32,000 security associations are supported with external DDR2 SDRAM.

The HIPP III 4450 processor will be sampling to lead customers in the second quarter of 2006. it comes in a 19-by-19mm, 324 BGA package and is priced at $84 in quantities of 10,000.
