Hex Five Announces MultiZone Security for Arm Cortex M Series Processors
Hex Five Security has made its MultiZone Security technology available to Arm Cortex-M processors including the Cortex M0+, Cortex M3, Cortex M4, and Cortex M7, as well as microcontrollers produced by Microchip, NXP Semiconductors, Renesas, STMicroelectronics, GigaDevice, and others.
Hex Five's MultiZone solution provides security without the need to add extra hardware or redesign the SoC, and eliminates the complexity associated with managing a hybrid hardware/software security scheme.
“Achieving truly robust security for a world of a trillion connected devices requires an ecosystem of partners who recognize security needs to be built-in from the ground up,” said Tim Whitfield, VP Strategy, Automotive and IoT Line of Business at Arm, in a press statement. “By collaborating with Hex Five, we are enabling our customers with more choices for foundational security across a broad range of Arm-based platforms.”
“The design complexity associated with traditional hardware isolation mechanisms often results in them not being used at all,” said Cesare Garlati, CEO and Founder of Hex Five Security, said in a press release. “To minimize human error, attack surface, and risk of system vulnerability, MultiZone encapsulates and hides the complexity of managing the underlying hardware security blocks. The only interaction between the developer and the trusted execution environment is a simple policy definition file. No coding, compilation, linking, and debugging required – or in fact even allowed.”
Hex Five says that, unlike traditional solutions, MultiZone is self-contained, presents an extremely small attack surface, and it is policy-driven – meaning that it doesn't require hardware or software redesign.
