QuestionQ11

Managing Encryption and Privacy

You are a Network Administrator for Tech Perfect Inc. The company has a Windows Server 2008 Active Directory-based network with a single domain and a single forest. The forest functional level is Windows Server 2008. The company headquarters is in Los Angeles, and a branch office is in Denver. You are preparing to send a message to Rick, a Network Administrator in Denver. You need to ensure that no one other than the recipient can read the message. Which of the following keys will you use to encrypt the message?

  • A Your public key
  • B The recipient's private key
  • C The recipient's public key
  • D Your private key
Explanation

Public-key cryptography provides confidentiality by encrypting data with the recipient’s public key; only the corresponding private key can decrypt it. Encrypting the message with Rick’s public key therefore ensures that Rick, as holder of the matching private key, is the intended party able to read it.
