Chacha20-Poly1305 Crypto Engine
The ChaCha20-Poly1305 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.
The ChaCha20-Poly1305 Crypto Engine is available for ASIC and FPGA, with simple interfaces and easy to integrate. It supports a wide range of applications on various technologies. The IP Core can be combined with scatter/gather DMA and AMBA interfaces (AHB/AXI) enabling multi-Gbps throughput in SoC solutions.
This Crypto Engine is also available in the eSecure IP solution (BA470)
