A framework for key management for data confidentiality in cloud environment

Cloud computing is a technique to keep the resources intact and available with internet facilities online at anytime and anywhere. A user may access cloud services as a utility service and can use them almost instantly. These features make cloud computing so flexible with easy access for unlimited users with several potential risks, thus demanding for the security mechanisms. Hence the need for cryptographic algorithm is inevitable for the transaction of data in a more secure manner, providing confidentiality and integrity of the data to the users. There are many numbers of cryptographic algorithms that make the system protected from the attacks of intruders. With the use of cryptographic algorithms, the keys are generated and the techniques are introduced to manage these generated keys. We make all the impossibility by use of management techniques for the intruders to break the key. These techniques act as a black box where the intruders have not even slightest glue for the key identification. In this paper the key management mechanisms are introduced which would help the users to manage the generated keys to protect the data in terms of confidentiality in cloud storage.
