Using the same key for both encryption as well as decryption is the key principle in symmetric algorithm. This mechanism involves the existence of centralized Key Distribution Centre also known as KDC, responsible for distributing and maintaining attributes and secret keys to its users. There also is a decentralized access control scheme used to make data storage in clouds more secure. The security in these security systems suffers a major drawback when one user requests for the sharing of data… CONTINUE READING
