Survey on Secure Data Self-Destruct Scheme & Division and Replication of data on cloud

Computer Engineering

There is always a risk of unauthorized users accessing the private data. Fine grained data loss prevention policies helps to manage what get stored in the cloud, how it gets stored and what stays on-premises. In this paper, we proposed using KP-TSABE (Key Policy-Time Specified Attribute Based Encryption) scheme for securely self-destructing data and DROPS (Division and Replication of data in cloud for Optimal Performance and Security) for secure storage in cloud.KP-TSABE policy used in this model is superior to other present schemes. DROPS scheme allows the data to be fragmented which are stored in the nodes separated by some distance by using graph T-coloring method for preventing data breach. Also we propose Time-Based One Time Password (OTP) for authentication of legitimate user and SHA-2 hash function for data integrity check. For encryption and decryption we propose modern Advanced Encryption Standard (AES) algorithm. Using all these levels of security slight overhead was observed in the performance of the system. By using high security techniques we aim to secure data within the cloud ecosystem.
