Silex Inside eSecure Root-of-Trust Security IP Is Excellent Fit with RISC-V Cores

6 July, 2018

Louvain-la-Neuve, Belgium – July 7, 2018 – Silex Inside, leading provider of IP cores for cryptography, announces that its comprehensive eSecure IP solution is also available for RISC-V architectures. eSecure is a silicon proven IP module that turns ASIC, FPGA or SoC designs into fully secured applications that guarantee the authenticity and integrity of the hardware, software, data, and communication. The solution is the most efficient on the market and is also highly scalable, making it suited for today’s IoT solutions as well as for more compute-intensive applications. eSecure can be integrated into almost any system architecture, including into cores based on the RISC-V instruction set.

Today, as forever more and diverse applications become connected in a global network, it is key to underpin systems with rock-solid, future-proof security. “We have a stellar reputation as supplier of such solutions in the form of IP modules, mainly for the excellent security, scalability, and ease of use,” says Thierry Watteyne, CEO of Silex Inside. “But we also go to great lengths to make our solution available for the widest variety of architectures. And that is why we now announce the compatibility of eSecure with RISC-V cores.”

eSecure acts as a Root-of-Trust. At its heart is a secure controller that takes full control over all security functions, especially those that shield the system’s secrets such as encryption keys from the main applications running on the product. The module also contains a scalable cryptographic engine supporting symmetric and asymmetric operations, secure debugging capability, authentication of components, firmware and application software, advanced anti-tampering features, protection against side-channel attacks, a secure storage interface, and much more. The cryptographic engine supports all latest algorithms for TLS/DTLS 1.3, Thread Networking, Apple HomeKit, Bluetooth, ZigBee and more. In a typical implementation, eSecure is implemented as a separate core on the SoC, a security coprocessor. This offloads the intensive cryptographic calculations from the main processor and prevents that the main application becomes temporarily unavailable.

“Our solution has been designed for ease of integration,” adds Pieter Willems, Sales Manager Security Products at Silex Inside. “And in addition our experts relish assisting customers and finding hardware security solutions for their innovative systems. So as the base of RISC-V systems is growing, we are excitedly anticipating a wave of new applications secured by eSecure.”
