Hex Five Security
San Jose’s Hex Five is the creator of MultiZone Security, what it calls the first trusted execution environment for RISC-V. MultiZone requires no additional hardware, dedicated cores, or programming models, and allows for policy-based, hardware-enforced separation for an unlimited number of security domains, with full control over data, code, interrupts, and peripherals. And since it’s open source, like RISC-V, engineers can also implement open course libraries, third-party binaries, and even old legacy code into MultiZone as well. Hex Five also maintains an open source repository for MultiZone on GitHub.
In February 2019, as part of a partnership with cryptography company wolfSSL, Hex Five released an industry-first secure Internet of Things (IoT) stack for RISC-V. The stack is designed to be implemented with FreeRTOS and to handle the security risks inherent in the embedded operating system.
MultiZone allows engineers to isolate the firmware into an unlimited number of separate zones, essentially walling them off from one another in terms of security. According to Hex Five, the result of this is preventing shared memory attacks and other exploits from spreading throughout the system. Any exploit is confined into the zone in which it happens.
wolfSSL and Hex-Five Security Bring Secure IoT Stack for RISC-V
wolfSSL, a provider of TLS cryptography, and Hex-Five Security, developer of MultiZone Security, have partnered to bring what’s claimed as an industry-first secure IoT stack for RISC-V. The move brings a TLS 1.3 reference application of FreeRTOS with hardware-enforced separation between OS, TCP/IP, and Roots of Trust (RoT). Hex-Five Security’s MultiZone Security compartmentalizes the monolithic firmware into an unlimited amount of physically isolated zones, which prevents attacks to the system from propagating to the rest of the platform and compromising the security layers.
wolfSSL’s TLS 1.3 library offers more robust security and increased speed, featuring wolfCrypt encryption, which supports FIPS 140-2 encryption that’s certified by the government and meets NIST (National Institute of Standards and Technology) standards. The stunnel TLS proxy is also supported, which allows already existing servers and clients to establish two-year connections without needing to change source-code programming. It’s useful for securing email exchange, remote shell, and web-hosting connections. The MultiZone Secure IoT Stack is now available for anyone on Hex Five Technology’s GitHub page.
Based on the instruction set architecture RISC-V from the University of Berkeley, processor cores are now being developed as IP and SoCs. Cesare Garlati, founder Hex Five Security and chief security strategist at prpl Foundation, follows the development closely.
San Jose, CA – Feb 25, 2019 /PRWeb/ – 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.
Hex Five is excited to collaborate with Dr. Sandro Pinto on the first Secure IoT Stack for RISC-V which will be
presented at Embedded World in Nuremburg, Germany on Feb 26-27, 2019. This demonstration will detailed
in sessions on Feb 26 and 27th and will be on display at the wolfSSL booth, Hall 4 / Booth 421.
