Key Features

Minimal Resource Requirements: The entire XIP4001C requires less than 1k Logic Elements and uses only 1-2 multipliers/DSP Blocks2 and one internal memory block in a typical FPGA implementation.
Constant Latency: The execution time of XIP4001C is independent of the key value, and consequently provides protection against timing-based side-channel attacks.
Performance: Despite its small size, XIP4001C can support more than 100 key exchange operations per second.
Standard Compliance: XIP4001C is compliant with RFC7748 [1], and can be used as a part of many public-key protocols including IKEv2 (RFC 8031) [3] and TLS 1.3 (RFC 8446) [4].
