Information flow control is a security mechanism that regulates how information can move within a computer system or network to prevent unauthorized disclosure or modification. It ensures that data access and propagation adhere to defined security policies, often by assigning security labels to information and processes. This control helps maintain confidentiality and integrity by restricting data movement between different security domains. It is a foundational concept in system security.
Context
In the context of blockchain and decentralized applications, information flow control is crucial for managing sensitive data and ensuring privacy. News might discuss protocols that implement sophisticated information flow controls to protect user data in zero-knowledge applications or to manage access rights within decentralized identity systems. Robust information flow control is vital for compliance and user trust in Web3 services.
