Questions and Answers

What security concern arises if the NFC communication is sent in the clear?

  • The Bluetooth pairing process may be compromised.
  • Unauthorized people may be able to decrypt the information. (correct)
  • Mobile devices may not be able to pair automatically.
  • It may lead to a denial-of-service situation.

    • How does NFC simplify the pairing process with Bluetooth devices?

  • By making the device search for available connections.
  • By using PIN numbers for added security.
  • By allowing devices to pair automatically when moved close to each other. (correct)
  • By requiring manual turning on of the pairing process.

    • What could happen if someone jams the frequencies associated with RFID communication?

  • It enables easy decryption of information through Google searches.
  • It might lead to unauthorized modification of RFID tag contents.
  • It allows for authentication of mobile devices.
  • It could cause a denial-of-service situation. (correct)
