Features and Benefits
- Optimized resource requirements:
- Requires 16904 4-input Lookup Tables (4LUTs) for Microchip® PolarFire® .
- Performance:
- Achieves a high throughput up to 50s of Gbps compliant with ChaCha20-Poly1305.
- Even higher throughputs can be achieved with parallel instantiations.
- Offers very high throughput for a single stream of data as it is capable to process one 16-byte block per clock cycle after certain initial latency.
- Length of the initial latency depends on the length of the message, this IP core has been carefully optimized to minimize this initial latency.
- Execution time is independent of the key values and message contents (apart from the message length), and consequently provides full protection against timing-based side-channel attacks.
- Standard Compliance:
- Fully compliant with RFC 8439 ChaCha20 and Poly1305 for IETF Protocols, modern cryptographic standards.
- Easy Integration :
- Pure RTL without hidden CPU or software components.
- Vendor agnostics FPGA/ASIC implementation.
