Key Features

Moderate resource requirements: The entire XIP2113B requires 5052 Adaptive Lookup Modules (ALMs) (Intel® Arria® 10 GX).
Performance: XIP2113B achieves a throughput in the tens of Gbps range2, for example 6.96+ Gbps in Xilinx® Zynq® MPSoC. Even higher throughputs can be achieved with parallel instantiations of XIP2113B.
High Throughput with Short Latency: XIP2113B 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. The length of the initial latency depends on the length of the message and XIP2113B has been carefully optimized to minimize this initial latency.
Constant Latency: The execution time of XIP2113B 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: XIP2113B is fully compliant with RFC 8439 “ChaCha20 and Poly1305 for IETF Protocols” [3].
