Hex Five Security Adds MultiZone Trusted Execution Environment to the SiFive Software Ecosystem

Enabling RISC-V Developers to a Robust Trusted Execution Environment without any changes to hardware or software.

SAN MATEO, Calif. -- Sept. 10, 2018 -- SiFive, the leading provider of commercial RISC-V processor IP, today welcomed Hex Five Security, maker of MultiZone™ Security – the first Trusted Execution Environment (TEE) for RISC-V, to the growing SiFive Software Ecosystem. Through the partnership, SiFive will incorporate MultiZone™ Security into its Freedom SDK for easy adoption by SiFive customers seeking a Trusted Execution Environment.

Hex Five's patent-pending technology provides policy-based hardware-enforced separation for an unlimited number of security zones, with full control over data, code, interrupts and peripherals. MultiZone's™ Configurator takes fully compiled and linked customer code and merges it with Hex Five's nanoKernel to enable rapid adoption without any changes to hardware or customer code basis.

"Hex Five is thrilled to partner with SiFive to bring MultiZone Security to a broader RISC-V community," said Cesare Garlati, Co-founder of Hex-Five. "History shows that the complexity associated with properly implementing security technologies often results in them not being used at all. Our mission is to enable mainstream adoption of security best practices by simplifying their deployment. With the addition of Hex Five's Trusted Execution Environment to the SiFive's Freedom SDK, RISC-V developers can easily build best-in-class security into their applications - greatly reducing time to market and technology risk."

The availability of Hex Five's MultiZone™ Security through the SiFive Software Ecosystem program shortens the time to market and removes common barriers to entry that have traditionally prevented companies from adopting robust security solutions. Companies like SiFive, Hex-Five and other software ecosystem partners provide low- or no-entry fee IP to emerging companies, minimizing the upfront engineering costs needed to bring a custom chip from design to realization.

"Hex Five Security provides a novel approach to build hardware-enforced, software-enabled security previously unavailable to the RISC-V community," said Shafy Eltoukhy, vice president of operations and head of the SiFive Software Ecosystem and DesignShare programs at SiFive. "With MultiZone Security as part of the SiFive Software Ecosystem catalog, RISC-V users now have a robust Trusted Execution Environment available that is fully integrated into SiFive's toolchain."
