Hex Five and wolfSSL Announce the First Secure IoT Stack for RISC-V

Secure implementation of freeRTOS with wolfSSL TLS 1.3 and hardware-enforced separation between OS, TCP/IP stack and root of trust.

SAN JOSE, CALIF. -- FEBRUARY 25, 2019 -- wolfSSL, a leading provider of TLS cryptography and Hex Five Security, provider of MultiZone™ Security, the first Trusted Execution Environment for RISC-V announce general availability of the industry-first secure IoT stack for RISC-V – a TLS 1.3 reference implementation of freeRTOS with hardware-enforced separation between OS, TCP/IP stack and root of trust.

FreeRTOS is the leading real-time operating system in the market; however recent security vulnerabilities identified in its connectivity stack highlight the risk inherent in monolithic system designs – the lack of separation between individual functional blocks where the exploit of one vulnerable area exposes the entire system to attack. The MultiZone™ Security Trusted Execution Environment allows to separate the monolithic firmware into an unlimited number of physically isolated zones, de-facto preventing shared memory attacks, privilege escalation and lateral movement: the exploit of any zone vulnerability is confined to that zone and doesn’t propagate to the rest of the system.

“Security through separation is a fundamental building block of a secure system – however legacy Trusted Execution Environments have only enabled one barrier which does not support the complexity of a modern IoT device.” Said Todd Ouska, CTO and co-founder of wolfSSL. “MultiZone Security on RISC-V enables an unlimited number of secure zones, providing the flexibility for a proper security implementation.”

“wolfSSL’s TLS 1.3 library is broadly recognized as the gold standard for crypto performance and code size.” said Don Barnetson, co-founder of Hex Five Security. “We’re excited to partner with wolfSSL to bring their capabilities to the broad RISC-V community and provide the first secure IoT stack implementation for RISC-V.”

The secure IoT stack for RISC-V is open source and available on GitHub at https://github.com/hex-five/multizone-secure-iot-stack.

Hex Five and wolfSSL will be presenting six papers describing all aspects of the underlying zero-trust framework at the Embedded World Conference in Nuremberg, Germany on Feb 26 and 27, 2019. https://www.embedded-world.eu/home.html
