High-Speed Elliptic Curve Cryptography Accelerator for ECDH and ECDSA

Overview

XIP4200H is an Intellectual Property (IP) core implementing Elliptic Curve Diffie Hellman (ECDH) and Elliptic Curve Digital Signature Algorithm (ECDSA). This IP core demonstrates a capability of executing over a thousand operations per second when deployed on a modern Field-Programmable Gate Array (FPGA) or Application-Speci€c Integrated Circuit (ASIC). The IP core comprehensively covers all NIST P curves, namely P-192, P-224, P-256, P-384, and P-521, within a singular IP core instance. It also facilitates the utilization of user-specified elliptic curves. The IP core includes hardened protections against multiple-trace side-channel attacks.

XIP4200H has been designed for easy integration with FPGA- and ASIC-based designs in a vendor-agnostic design methodology, and the functionality of XIP4200H does not rely on any FPGA manufacturer-specific features.

Key Features

High Speed:
- XIP4200H is optimized for high speed. For example, a key generation on NIST P-256 requires approximately 180k clock cycles, and XIP4200H can compute over a thousand operations per second on modern high-speed FPGAs and ASICs
Versatile Curve Support:
- XIP4200H natively supports all NIST P curves within a single IP core instance. Customer-specified curves can be added into the set of upported curves.
Secure Architecture:
- Execution time and pattern of operations are independent of the secret values providing full protection against timing-based side-channel attacks. XIP4200H includes hardened protections against multi-trace side-channel attacks (for example, DPA). XIP4200H is fully RTL-based with no embedded software or CPU components.
Standard Compliance:
- XIP4200H is compliant with FIPS 186-5 and SP 800-56A. XIP4200H and can be used as a part of numerous public-key systems and protocols including IKEv2 and TLS 1.3.
Easy Integration:
- The simple 32-bit interface supports easy system integration.
