Compact RSA Signature Verification Accelerator for Constrained Devices
RSA signature verification is widely used in secure boot and code authentication, yet it can strain the limited computational resources of low-power embedded systems. FortifyIQ’s FIQ-PKA04C is a compact and efficient RSA verification IP core optimized for SoC integration in resource-constrained environments. Designed specifically for public-key operations, it requires no countermeasures against side-channel or fault injection attacks. Supporting RSA-4096 with fast modular arithmetic, FIQ-PKA04C enables standards-compliant cryptographic verification with minimal area and power consumption, ideal for secure applications that demand lightweight, high-assurance public-key validation.
FortifyIQ’s FIQ-PKA04C is a compact IP core for RSA signature verification, optimized for fast, standards-compliant public-key operations in resource-constrained environments. Supporting RSA-4096 compliant with FIPS 186-5, it delivers efficient signature validation with minimal area and power consumption, ideal for secure boot, firmware authentication, and digital signature checking.
Since only public-key inputs are processed, no countermeasures against physical attacks (e.g., side-channel or fault injection) are required. This streamlines integration and reduces overhead while maintaining compatibility with cryptographic standards.
A patented high-performance modular exponentiation engine contributes to the core’s speed and compact footprint. The design is implementation-agnostic and suitable for ASICs, SoCs, and FPGAs, offering flexible interfacing via AMBA AHB, APB, AXI, or custom memory-mapped protocols. Optional firmware support is available via internal RAM or ROM, and the included HAL and software libraries simplify integration. FIQ-PKA04C is designed for straightforward deployment in systems requiring reliable and efficient RSA signature verification.
