- B B. It is a type of encryption that uses block chain technology to secure data
- C C. It is a method of securing communication by using radio waves
- D D. It is a type of encryption that uses sequence of photons
Reveal correct answer
Correct answer: D
Explanation
Correct Answer: D. It is a type of encryption that uses sequence of photons Explanation: Quantum cryptography is a method of securing communication that involves encrypting data using a sequence of photons, which are particles of light. The photons are used to create a secure key that is then used to encrypt and decrypt the data. The security of the communication is based on the principles of quantum mechanics, which provide a high level of security due to the difficulty of intercepting or eavesdropping on the communication without disturbing the quantum state.Discussion
