A start-up founded by a group of ex-HP executives, including the chief architect behind Itanium, officially debuted Monday and announced plans to ship software this summer that promises to boost the speed and security of Web applications on Itanium servers.

Secure64 Software was founded in 2002 and currently employs 16 people at its Englewood, Colo., headquarters. It bills itself as a 64-bit software development company “poised to dramatically improve the security and performance of network communications.” Its software is being built specifically for Itanium processors.

The company was co-founded by Bill Worley, who was technical director and principal architect of PA-RISC and PA-Wide Word, which became Itanium, at HP. Worley, Secure64’s vice president and CTO, currently has three patents pending for Secure64’s secure platform software.

Worley says today there is no software that takes full advantage of the Itanium architecture, which offers enhanced security capabilities with four privilege levels and compartmentalization, for example. In addition, it can run as many as eight instructions per cycle, offering significant performance gains over other platforms.

Instead, most operating systems have gotten bulky because they are designed to be general-purpose and run on multiple platforms. Security is an issue with these operating systems because with their general-purpose nature they don’t tap into hardware-level security available on chips such as Itanium.

Secure64 aims to leverage the unique speed and security features in the Itanium architecture that are not employed by current operating systems such as Windows and Linux, Worley says.

For example, today’s operating systems typically use two security levels on the hardware platforms they run on. Secure64’s software will use all four of Itanium’s security levels, Worley says. As for performance, Secure64 executives say Pentium-architecture chips run just one instruction per cycle, and RISC-based processors max out at three instructions per cycle, while Itanium’s Explicitly Parallel Instruction Computing design can run eight instructions per cycle.

Secure64’s aim is to reduce complexity in an operating environment by focusing strictly on Itanium’s unique features, says Peter Cranstone, co-founder and CEO of Secure64 and a co-developer of data compression technology mod_gzip for Apache.
