# Quantum Secure DIDs

A Rebooting the Web of Trust (RWOT) community paper on making a DID method resistant to quantum attack with existing signing and hashing primitives. It proposes publishing only hashes of public keys and rotating keys after every signing operation, and points to KERI's pre-rotation as one way to do so. For designers of DID methods and decentralized identity systems.
