Xiphera's ChaCha20-Poly1305 is an Authenticated Encryption with Associated Data (AEAD) scheme that combines the ChaCha20 stream cipher and Poly1305 message authentication code. It is used in protocols like TLS 1.3 as an alternative to AES-GCM and is the only accepted cipher in WireGuard, a modern VPN protocol. Xiphera offers both balanced and high-speed IP cores for ChaCha20-Poly1305, designed for easy integration with FPGA- and ASIC-based designs using a vendor-agnostic methodology.
