Question

    Which cryptographic system uses two different keys for

    encryption and decryption?
    A Symmetric key cryptography Correct Answer Incorrect Answer
    B Asymmetric key cryptography Correct Answer Incorrect Answer
    C Hashing Correct Answer Incorrect Answer
    D Digital signatures Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    In asymmetric key cryptography, also known as public key cryptography, a pair of keys is used: a public key for encryption and a private key for decryption. This approach allows secure communication without the need for a shared secret key.
