Explanation
The following are the weaknesses of symmetric key cryptography: 1.The key distribution is difficult. Symmetric key cryptography requires the secure method to exchange the secret keys before the communication is initiated. 2.Symmetric key cryptography does not apply Nonrepudiation. It becomes difficult to determine the real originator of the message. 3.The algorithm used for symmetric key cryptography is not scalable. It becomes difficult for large groups to communicate using symmetric key cryptography. 4.It often requires the keys to be regenerated. All the keys used by a participant are discarded when the participant leaves the group.
