Effective Data Retrieval for Virtual Chunk and Data Partitioning Using Encryption Technique

Abstract

Data partitioning is normally done for manageability, performance or availability reasons, as for load balancing. In existing system, Data compression could ameliorate the I/O pressure of data-intensive scientific applications. Virtual chunks are logical blocks pointed at by appended references without breaking the physical continuity of the file content. In the proposed system,the I/O performance of random data access in scientific applications and high-performance computing (HPC) system is strengthen to split and store the data efficiently using dynamic virtualization concept.Attribute-based encryption is a type of  public-key encryption in which the secret key of a user and the cipher text. Attribute-based encryption based keys are distributed among the corresponding admin so that access policy is applied. The proposed algorithm will reduce the time for fetching I/O performance results from the table.
