PUFsecurity, a security solutions IP company, and Andes Technology, a leading RISC-V CPU IP vendor, are the first to incorporate PUFsecurity’s PUFiot crypto coprocessor with Andes Technology’s D25F CPU and its associated platform AE350. With this successful integration, PUFiot will become a part of the AndeSentry™ security framework from Andes Technology, offering a rich set of security solutions for the RISC-V ecosystem.

PUFsecurity jointly develops the security solution PUFiot with eMemory, combining eMemory’s innovative NeoPUF, a physically unclonable function (PUF) that could be the chip fingerprint, along with the leading anti-fuse one-time programmable (OTP) memory, NeoFuse, and PUFsecurity’s root of trust and NIST CAVP-certified cryptographic engines (including symmetric/asymmetric ciphers, hashes, key wrapping, message authentication, etc.). Featuring multiple analog/digital anti-tampering designs to prevent both invasive attacks (such as those utilizing focused ion beam, FIB) and non-invasive ones (such as side-channel analysis), PUFiot provides a solid security boundary for chip protection.
Using PUF-derived chip fingerprints to internally generate key pairs and inborn IDs, PUFiot lowers the cost of supporting zero-touch deployment to meet the secure onboarding requirements of AI/IoT/5G multi-terabyte, networked devices. In other words, PUFiot can assist cloud-based application ecosystems in achieving zero-trust compliant security operations.

Andes Technology’s RISC-V D25F is a 32-bit high-performance processor core that supports single/double-precision floating-point operations, RVP P-extension (DSP/SIMD) instructions and Physical Memory Protection (PMP). The pre-integrated AE350 platform comprises AHB/AXI bus matrix, interrupt control, debug module, and commonly used peripherals such as GPIO, I2C, PWM, QSPI, UART, and WatchDog Timer. It greatly simplifies the SoC construction for customers. D25F processor with the AE350 platform have already been licensed to many customers for use in a broad range of market, including the emerging AIoT applications.
AndeSentry™ security framework enables open collaboration and brings out a variety of security solutions. Now included in AndeSentry™, PUFiot provides secure storage, root of trust, and hardware cryptographic engines. When integrated with the D25F+AE350 platform, PUFiot supports system-level security features such as secure boot/OTA (over-the-air) updates and firmware/software protection. The combined solution is ideal for the growing secured AIoT applications.
The successful partnership between Andes Technology and PUFsecurity is a significant milestone for the security IP industry, which will lead to the development of even more cost-effective hardware security solutions for the RISC-V ecosystem.
