Cloud files Storage System with Encryption

Abstract

Without relying on a third party, attribute-based encryption (ABE) offers safe data storage and sharing to data owners in cloud contexts. The previous ABE schemes only had one authority for end-user verification, resulting in a bottleneck at a single point for performance and security. The guarantee the privacy and verification of various attribute subsets, too many multi-authority approaches are offered. However, single-point bottleneck problems are difficult to resolve in many systems. In this proposed research project, the system presented a secure data transmission in cloud settings by focusing on a multi-authority verification mechanism called Robust Access Control (RAAC), a Role Base Access Control (RAC) component. With RAAC, various authorities, middleware, and other trusted parties may share the master and private keys by taking advantage of (t out of n) threshold secret sharing. An authorized user may create a secret key by working with any public authority on the transaction. The PBEWithMD5AndDES encryption offers the best level of data protection when combined with key with middleware authority and two kinds of cipher text policies. Furthermore, we create a method to verify several users concurrently and provide consistent data to end users by skillfully combining the traditional multi-authority system with RAAC. The experimental study also demonstrates how superior the current techniques to the new ones are.
