Question

When a sender encrypts a message using their own private key, which security service is being provided to the recipient?

a) Non-repudiation
b) Availability
c) Integrity
d) Confidentiality

Answer 1

The recipient is provided with confidentiality when a sender encrypts a message using their own private key.

Step-by-step explanation:

The correct answer is d) Confidentiality.

When a sender encrypts a message using their own private key, it ensures that only the recipient who possesses the corresponding public key can decrypt and read the message. This provides confidentiality because any other party without the private key cannot decipher the encrypted message and gain access to its content.
