Homework Help: Questions and Answers: Which of the following components does a digital certificate include?
A. It guarantees the company sells quality products.
B. It verifies the usefulness of the server.
C. It verifies the server’s identity.
D. It verifies its own authenticity.
Answer:
First, let’s understand what digital certificate is:
A digital certificate is an electronic document used to prove the ownership of a public key. It helps ensure that a user’s communication with a server is secure and that the server is the one it claims to be.
Components of a digital certificate:
- Identity Verification: Verifies that the server or entity is legitimate.
- Public Key: The certificate includes the public key of the entity, which is used for encrypting data or verifying signatures.
- Issuer: Information about the certificate authority (CA) that issued the certificate.
- Validity Period: The time frame during which the certificate is valid.
- Digital Signature: A signature from the certificate authority to confirm the authenticity of the certificate.
Given Options: Step by Step Answering
a) It guarantees the company sells quality products
- Digital certificates do not relate to the quality of the products sold by the company. They are used for authentication and security, not product quality assurance.
b) It verifies the usefulness of the server
- A digital certificate does not verify how useful a server is. Instead, it ensures that the server is secure and trustworthy, but usefulness is subjective and not part of the certificate’s function.
c) It verifies the server’s identity
- This is the key purpose of a digital certificate. It verifies that the server or entity is who it claims to be, ensuring trust in the communication between the client and the server.
d) It verifies its own authenticity
- While the certificate contains information about its authenticity (signed by a certificate authority), it does not verify itself. The verification of authenticity is done by the certificate authority (CA).
Final Answer:
Based on the above analysis, the correct answer is:
C. It verifies the server’s identity.
