The Hypothesis
Because of the distributed nature of the cloud model, it necessarily involves more and more transmissions of data over the network. Thus introducing new challenging security risks. As there is massive amount of data present in cloud and the popularity that cloud computing has gained over the years, Security ranked first as the greatest challenge or issue of cloud computing for all who are using it and also those who want to utilize it but they would be unable to do so because till now no one assure security in cloud.
2.1 Data Loss
Data loss, which means loss of data on any device that is capable of storing data. It is a common problem for anyone who uses a computer. Data loss occurs when data may be physically or logically deleted …show more content…
Firstly, the client sends its SSL version number, settings of the cipher, data specific to this session, and other information that are needed by the server to communicate with the client using SSL.
2. Then server sends the client the server's SSL version number, settings of the cipher, data specific to this session, and all the other information needed by the client to communicate with the server over SSL. The server sends its own certificate, and if the server requires client authentication then the server also requests for the client's certificate.
3. The client uses the information sent by the server to authenticate the server. If the server cannot be authenticated, then the user is warned of the problem that an encrypted and authenticated connection cannot be established with the server. If authentication is successful, the client proceeds to step 4.
4. Client, using all data generated in the handshake thus far (with the cooperation of the server, depending on the cipher being used and SSL version number and cipher settings) creates the pre-master secret for the session, with the help of server's public key it encrypt it (obtained from the server's certificate received in step 2), and then it sends the encrypted pre-master secret to the
