  • Q5
    What is the key difference between symmetric and asymmetric encryption in terms of key management?
    Symmetric encryption does not require key management, while asymmetric encryption involves complex key distribution.
    Both symmetric and asymmetric encryption use the same key management approach.
    In symmetric encryption, a single key is shared among communicating parties, while in asymmetric encryption, each party has a pair of unique keys (public and private).
