Cloud Based Secure File Storage Using Hybrid Cryptography Algorithm


Now a day’s Cloud computing is employed in serveral areas like industry, millitary collèges etc. to storing large quantity of data.We can retrieve data from cloud on request of user. To store data on cloud we mine to figure many issues. To provide the solution to these issues there are n numbers of ways. Many issues are faced while storing the data, the solution for these issues we are using hybrid cryptography technique. Use of a simple algorithm is not effective for high level Security to data in cloud computing. In this system,AES, DES,RC2 algorithm are used to provide block Wise security to the data.All algorithm key size is 128 bit.LSB sténographie technique is introduced for key information security. Key information contains which part of file in encrypted using by which algorithm and key. Distributed computing in present is a creating and quickly developing arrangement of IT benefits that are given to a client over web on rented premise and with the capacity to scale up or down their administration prerequisites. It uses the intensity of web based processing and how the information, data and different assets can be shared to the client by means of PC or gadgets on interest. This audit has been locked in with how to safely store data and information into the distributed storage and, what are the arrangements that have been taken to beat the security issues. What's more, it is talked about that how to utilize the cloud assault and cryptographic strategies and methods to take care of these issues. Keywords: Cloud Security, Cloud Computing, Encryption/Decryption Cryptography Techniques.
