wolfSSL, a leading provider of TLS cryptography and Hex Five Security, provider of MultiZone™ Security, the first Trusted Execution Environment for RISC-V have announced the general availability of the industry-first secure IoT stack for RISC-V – a TLS 1.3 reference implementation of freeRTOS. This comes 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.”
