Which of the following scheme helps to provide nonrepudiation?
Show Hint
Confidentiality \(\rightarrow\) Encryption
Nonrepudiation \(\rightarrow\) Digital Signature
Updated On: Jun 25, 2026
- RSA algorithm
- One Time Pad
- Digital Signature
- Substitution Cipher
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Concept:
Nonrepudiation means that the sender cannot deny sending a message.
It provides proof of origin.
Step 1: Understand Digital Signatures.
A digital signature is generated using the sender's private key. The receiver verifies it using the sender's public key.
Step 2: Security services provided.
Digital signatures provide:
• Authentication
• Integrity
• Nonrepudiation
Step 3: Select the correct answer.
Therefore, \[ \boxed{\text{Digital Signature}} \] provides nonrepudiation.
