Quantum-resistant Interoperable Encryption Standard. Security framework planned for use across the Autheo stack for post-quantum data protection, rolling out over the coming months.

Last updated: April 2026Reviewed by: Autheo Technical Team

QIES (Quantum-resistant Interoperable Encryption Standard) is the planned security framework intended for use across the Autheo stack for post-quantum data protection, rolling out over the coming months and not yet threaded into the live system. It is designed to define how encryption, key exchange, and digital signatures will be handled throughout the platform, with the goal of providing consistent quantum-resistant security across identity (TheoID (formerly AutheoID)), decentralized storage and decentralized compute capacity through the coming Autheo Marketplace, and network communication layers, as those layers roll out over the coming months. QIES is designed to be interoperable, meaning encrypted data and signed messages will be verifiable across different components of the Autheo ecosystem without requiring separate encryption schemes for each layer.
