Balanced IP Core for ChaCha20-Poly1305 Authenticated Encryption

XIP2113B from Xiphera is a balanced Intellectual Property (IP) core designed for ChaCha20-Poly1305 Authenticated Encryption with …

Overview

XIP2113B from Xiphera is a balanced Intellectual Property (IP) core designed for ChaCha20-Poly1305 Authenticated Encryption with Associated Data (AEAD) scheme protecting both confidentiality and authenticity at the same time. The current definitive standard for ChaCha20-Poly1305 is RFC 8439, “ChaCha20 and Poly1305 for IETF Protocols”.

ChaCha20-Poly1305 is a combination of the ChaCha20 stream cipher and Poly1305 message authentication code, both algorithms designed by Daniel J. Bernstein, and it is used an AEAD scheme in multiple protocols, including TLS 1.3.

XIP2113B has been designed for easy integration with FPGA- and ASIC-based designs in a vendor-agnostic design methodology, and the functionality of XIP2113B does not rely on any FPGA manufacturer-specific features.

Key features

  • Moderate resource requirements: The entire XIP2113B requires 5052 Adaptive Lookup Modules (ALMs) (Intel Cyclone 10 GX).
  • Performance: XIP2113B achieves a throughput in several Gbps range, for example 2.99+ Gbps in Intel Cyclone 10 GX. 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”.

Why Post-Quantum Cryptography Doesn’t Replace Classical Cryptography

As quantum computing advances, discussions around the future of cryptography are becoming increasingly common. In many conversations, one message is often heard: in the future, only quantum-safe cryptography will be needed. While quantum computing does introduce real risks to certain cryptographic systems, the reality is more nuanced. Future secure systems will not solely on a single “quantum-safe” algorithm. Instead, they will continue to combine multiple cryptographic technologies.
