Question

Charles Mott works for a company called VeriSign that acts a trusted third party to verify information. One of Charles' largest clients is CheckMd, which holds and authenticates customer reviews of doctors and dentists online and having a third party validating the reviews is critical to CheckMd's success. What type of authentication technique is VeriSign providing for CheckMD?

Answer 1

Answer: Certificate authority

Explanation: Certificate authority is provided by VeriSign to the CheckMD in the form of digital certificate .The trusted third party issues this certificate to the other two parties to assure about the validation of the identity under the public-key infrastructure.

This certificate is also known as certificate authority (CA). This keeps the assurance about ownership of the public key. Thus, CheckMD gains the certificate authority from VeriSign.
