Non-Repudiation refers to the assurance that actions or events can be proven to have occurred so that they cannot be denied later by any party involved in a transaction or communication process.
Key Elements:
- Authentication: Verifying the identity of participants in a transaction.
- Integrity: Ensuring that messages or data have not been altered during transmission.
- Logging: Maintaining records of actions taken by users or systems for future reference.
Non-repudiation is crucial in legal contexts and secure communications to provide accountability and traceability for actions taken within systems.
