Effective and secured dynamic key generation over cloud data
K Raja, Dr. R Sugumar
Cloud storage security may take as some advantages and disadvantages too. Many companies and private sectors are providing cloud storage with low cost and allocate space according to their requirements. Meanwhile security lack still remains afraid for some users. In fact, everyday users overcome lot of security issues behind cloud data sharing. So they produce advert of high secure and sharing data. But still doubt remains for many clients. For that security purpose developers implemented cryptography concepts between the client and server. They made some key concepts for the encryption. It is the process of converting normal text to cipher text. For this convention we need key and for decrypt also. So developers should take more care of highly secured key and spires couldn’t able to guess the key. In this paper we created dynamic key changes algorithm for the encryption. So the pirates cannot guess the key. Proposed can protect the data while transferring, sharing and storing in data centers using Dynamic key generation. It is the process of creating unique key changes when the user read their own data. The changes of key depend upon the user action. So it is very effective and secure transmission of data over cloud. This proposed process creates highly secure cloud data even any unknown person cannot guess the key. This paper mainly deals with the key management concepts and how it creates the dynamic key generation over cloud. It provides specific authentication to the user. Key takes major place to encrypt the files and process done by virtual because we cannot able to see the process of creating the key for encryption.
