Improved Self-destructing Scheme by Fine grained approach in Cloud Computing
Main Article Content
Abstract
Cloud computing, a recent computing technology entirely changed the IT industry. Large amount of data can be stored in cloud storage system. Security is the prime concern for this large amount of data. Without, knowledge of authorized client, data can be viewed by other user. This data contain personal information like, account number, password and notes. All the data and their copies become self-destructed after user specified time, without any user intervention. Fine grained approach is used for authorized data accessing, which provides high secured authorization for data accessing thus it achieves data confidentiality. Self-destruction method is consociated with time to live (TTL) property to specify the life time of the keys. After user specified time (TTL) data and its keys becomes destructed or unreadable. Self-destruction mechanism helps reducing overhead during upload and download process in cloud.
