Interphase Showcases Internet Protocol Security Accelerator Cards

8/6/2003 - Interphase Corporation (NASDAQ: INPH), an international supplier of next-generation networking technologies, demonstrated the performance of its newly launched Internet Protocol Security (IPSec) security acceleration cards at the LinuxWorld Conference in San Francisco, CA (Booth #1343).

Recent performance testing on the Interphase security acceleration cards demonstrated a three times system improvement on TCP throughput rates and a 63% decrease in host CPU utilization when IPSec protocols are accelerated on a Linux platform using the FreeS/WAN IPSec stack software. In summary, adding software encryption to a server can slow it almost to a halt. Adding Interphase network security acceleration adapters enables processor performance to return, thereby saving processor resources for applications, not just for encryption.

The 45NS (PMC) and 55NS (PCI) network security acceleration adapters are designed to eliminate the bottleneck on network traffic caused by today’s VPNs, gateways, secure routers and firewalls. Integrating the Interphase security accelerator cards into these applications will increase network efficiency and response times by offloading bandwidth-intensive IPSec security protocol processing from the host CPU in systems. By providing intelligent packet processing, the 45NS and 55NS modules can perform a variety of functions for addressing the complex security needs of today’s enterprise and carrier grade systems, including header analysis, payload extraction, compression, encryption, authentication and packet assembly.

Based on the Hifn 7854 security processor, the 45NS and 55NS adapters accelerate basic security algorithms including DES, 3DES, MD5, SHA-1, RC4 and AES. Other product features include a 64-bit, 66MHz PCI bus with universal signaling, 64 Mbytes of private memory for security session data and parameter storage, and support for full-duplex OC-3 (155Mbps) rates and 512K simultaneous sessions. Based on PMC and PCI specifications, the 45NS and 55NS have the flexibility to operate in a variety of environments, including CompactPCI, PCI, VME and proprietary systems.

"Hifn's HIPP 7854 performs all the packet and protocol processing that is required to turn clear text into encrypted data, thus freeing network processors to conduct other routing and control functions," said Doug Makishima, Vice President of Marketing at Hifn. "Interphase's 45NS and 55NS are premium IPSec acceleration products featuring high-performance security acceleration and system offload at attractive prices."

During the three-day LinuxWorld Conference, Interphase will demonstrate the performance of a system running FreeS/WAN without the Interphase security accelerator card versus a system incorporating the Interphase 55NS accelerator card. The demonstration will feature a server with a 55NS installed and two workstations, one of which has a security acceleration adapter installed. The other workstation has no offload adapter installed. Each workstation will run version 2.4 of the Linux kernel and version 1.99 of the open source FreeS/WAN IPSec software stack. TCP/IP traffic will be transmitted from each of the two workstations to the server while measuring throughput. MPEG video files residing on the server hard drive will be transmitted from the server to each workstation and played. The demo will show the throughput gained while minimizing CPU utilization.

"Exhibition of our network security accelerator cards at the LinuxWorld Conference and other venues will demonstrate the degree of improvement in system performance that the 55NS and 45NS provides," said Randall McComas, Vice President of Sales and Marketing at Interphase. "These security co-processors will enable developers to significantly increase system throughput and decrease host CPU utilization - an improvement that will benefit network administrators and ultimately end users by reducing network bottlenecks. Enhancements to network services such as these are the foundation of the Interphase value proposition of enabling our OEM customers to better serve their carrier and network administrator customers."

The 45NS and 55NS are currently shipping with standard software support for RedHat Linux 7.3 and greater running on an Intel processor, with integration into the FreeS/WAN IPSec stack v1.99.
