Data Sensitive Algorithm Integrated with Compression Technique for Secured and Efficient Utilization of Cloud Storage

The success and popularity of cloud computing is obvious from technological advancement. It is gaining confidence of clients by offering cost effective architecture supporting computation transmission and data storage. These trustworthy data services face lots of challenges just because of loss of control over data as well as cloud abstract nature. For handling security related issues, lots of encryption – decryption algorithms have already been designed and implemented. All of pre-existing algorithms require key from the user and then start encryption accordingly. The main objective of this research paper is to design and implement new algorithms that can produce key on sensing data automatically and consequently encrypt data on the basis of key produced. Algorithm1 has been designed into phases, in first phase it senses the data and generates key, in second phase it encrypts the data and in third phase it compresses the data. Algorithm2 has also been design into phases, in first phase it decompresses, in second phase it decrypts the data. Algorithm3 has been designed only. Its implementation is under progress and may be seen in future scope of the paper. For securing data, we have used the concept of encryption-decryption and for efficient utilization of cloud storage we have compressed the data by using GZIP java inbuilt library with ZIP package. Collectively Algorithm1 and Algorithm2 have been entitled as Data Sensitive Algorithm (DSA).
