Enhanced cloud data security using AES algorithm

Cloud computing is the revolution through which individuals can share resources, services and data among the users through the network. Since millions of users uses the same network for data transfer, the data becomes more vulnerable to different security attacks from intruders. Providing security to these data has become the critical area of concern. The current system for data security concentrates on providing security to the stored data in cloud storage but concerns less on securing the data while it is being transferred. The data becomes prone to intruder attacks while being transferred. Also, in the current existing trend, the third party auditor is given access to data during data transfer. This also increases the access vulnerability of data as the intruder could act as third party and gain access to the data. Considering security as a crucial issue, the system proposed concentrates on providing security to transferring data using encryption technique. The system also takes into consideration the issue concerned with the third party auditor, that in the proposed approach, the auditor is denied access to the user data. Experiments are conducted and has shown that the proposed approach increases the overall security of system by making it difficult for intruders to crack the data being transferred.
