Noise Protocol Framework

<p>The Noise Protocol Framework, sometimes referred to as "Noise" or "Noise Framework", is a <a href="/facts/Public_domain/YWKMDKw4">public domain</a> cryptographic <a href="/facts/Conceptual_framework/47772FXG">framework</a> for creating <a href="/facts/Secure_channel/cWucANvf">secure communication</a> <a href="/facts/Communication_protocol/5uady7cB">protocols</a> based on <a href="/facts/Diffie%25E2%2580%2593Hellman_key_exchange/xR4YQcaD">Diffie–Hellman key exchange</a>. Developed by Trevor Perrin, the framework defines a series of <a href="/facts/Handshake_(computing)/fqKIh1VW">handshake</a> patterns—predefined sequences of message exchanges—that outline how parties initiate communication, exchange keys, and establish <a href="/facts/Shared_secret/ATRz7LXy">shared secrets</a>. These patterns can be combined and customized to meet specific security requirements, such as mutual authentication, <a href="/facts/Forward_secrecy/ojScslsj">forward secrecy</a>, and identity protection.
</p><p>Several popular <a href="/facts/Software_applications/YQuj7Kog">software applications</a> and <a href="/facts/Protocols_(computing)/5uady7cB">protocols</a>, including the messaging platforms <a href="/facts/WhatsApp/VMlSeFb6">WhatsApp</a> and <a href="/facts/Slack_(software)/I51UWn6j">Slack</a> and the VPN protocol <a href="/facts/WireGuard/zSJv87LA">WireGuard</a>, have used implementations of the Noise Framework to ensure <a href="/facts/End-to-end_encryption/e1MwRzEU">end-to-end encryption</a> for user communications. The framework remains a topic of development, including <a href="/facts/Post-quantum_cryptography/1qeqUQve">post-quantum</a> adaptations. The framework is currently at revision 34, published in July 2018.
