What is the main purpose of non-repudiation in digital communications?

• A. To validate user credentials for network access
• B. To restrict access to sensitive data
• C. To ensure the integrity of a digital signature's transmission
• D. To track network device activities

Answer: (C)

The main purpose of non-repudiation in digital communications is to ensure that a digital signature's transmission is both secure and verifiable. Non-repudiation provides a means to confirm the authenticity of a message or transaction and prevents the sender from denying that they sent the message. This is vital in ensuring accountability and trust in electronic communications, especially in legal and financial contexts. In practice, when a digital signature is properly implemented and secured, it serves as proof of the origin and integrity of the message, linking it to the sender in a way that cannot be refuted. This aspect of non-repudiation helps maintain the integrity of communications and fosters trust in digital interactions.
