What does non-repudiation ensure in a transaction?

Non-repudiation ensures that parties involved in a transaction cannot deny their participation. This is a crucial aspect of digital communications and transactions, as it provides a way to guarantee the authenticity and integrity of the data exchanged. By implementing measures such as digital signatures or certificates, non-repudiation establishes a clear and verifiable record that a specific participant engaged in the transaction and approved the actions or agreements made.

In the context of cybersecurity and electronic transactions, non-repudiation plays a vital role in establishing trust, as it protects against any disputes or accusations regarding the authenticity of the communication. It holds individuals accountable for their actions, thus enhancing the overall security and reliability of digital interactions.
