Features and Benefits
- Latency:
- The execution time of this IP Core is independent of the message and key values (apart from message length), and consequently provides protection against timingbased side-channel attacks.
- Standard Compliance:
- Fully compliant with RFC7748, RFC8032, and the draft vesion of FIPS 186-5.
- Can be used as a part of many public-key protocols including IKEv2 (RFC 8031) and TLS 1.3 (RFC 8446).
- Easy Integration :
- Pure RTL without hidden CPU or software components.
- Vendor agnostics FPGA/ASIC implementation.
- Performance:
- Despite its small size, it can support more than 100 key exchange operations per second.
- High throughput Compliant with FIPS 186-5, SP 800-186, SP 800-56A, RFC 7748, RFC 8446, and more.
- Supports all NIST P curves and user-specified elliptic curves Secure architecture with side-channel protections.
- Compact Size:
- Has compact size, requires 2933 logic elements (PolarFire® ) and uses only 1-2 multipliers/DSP Blocks and 1-2 internal memory block in a typical Microchip® FPGA implementation.
