The ChaCha20-Poly1305 Multi-Booster Crypto Engine is RFC7539 compliant to provide Authenticated Encryption with Associated Data (AEAD) using the ChaCha20 stream cipher combined with the Poly1305 message-authentication code.

This Crypto Engine targets high-performance applications, where a high throughput is required (up to several hundred of Gbps). Thanks to its scalability, it can be tailored to reach the best trade-off between performances, area and technology.

Overview
The ChaCha20-Poly1305 Multi-Booster Crypto Engine is available for ASIC and FPGA, with simple interfaces and easy to integrate. The unique architecture enables a high level of flexibility. The throughput and features required by a specific application can be taken into account in order to select the most optimal configuration for any FPGA or ASIC technology. The Crypto Engine can be combined with scatter/gather DMA and AMBA interfaces (AHB/AXI) enabling very high throughput in SoC solutions.
