Verifiable Key Directory

Definition ∞ A verifiable key directory is a cryptographic system that allows users to securely publish and retrieve public keys while ensuring the integrity and authenticity of the directory itself. Participants can verify that keys have not been tampered with or revoked without relying on a single trusted authority. This system is crucial for secure communication and identity management in decentralized environments. It enhances trust by providing cryptographic assurances of data correctness.
Context ∞ Verifiable key directories are essential for establishing trust and security in decentralized communication protocols and identity solutions. Research often focuses on optimizing their efficiency and resistance to censorship or manipulation. Observing advancements in cryptographic commitments and distributed ledger technologies provides insight into the ongoing development of secure public key infrastructure.
