User Authorization

Definition ∞ User authorization is the procedure for confirming if an identified user possesses the requisite entitlements to execute a particular operation or access a specific resource within a system. This stage succeeds user authentication and establishes the permissible actions an individual may undertake. In blockchain and decentralized applications, it typically relies on cryptographic signatures and smart contract programming. It dictates access rights within digital environments.
Context ∞ The subject of user authorization constitutes a vital security element often addressed in news pertaining to blockchain network defense, access management for decentralized applications, and digital identity solutions. Reports frequently detail advancements in decentralized identity systems and zero-knowledge proofs that augment privacy and granular control over permissions. The strength of authorization frameworks is essential for safeguarding digital assets and preserving the coherence of decentralized infrastructures.
