Secure data storage and accessing in cloud computing using enhanced group based cryptography mechanism

Abstract Cloud computing (CC) has become generally recognised as a computing model. CC 's key purpose is to reduce the need for consumer expenditure in new hardware or applications by providing scalable cloud resources , allowing consumers to take advantage of the pay per use strategy. CC ensures that certain protection and privacy concerns be addressed: all challenges and remedies (vulnerabilities, risks and attacks). The study addresses both these problems and solutions as protection concerns, safety issues or interlinked defence and safety issues. The report explores both the problems and solutions. The study primarily makes two contributions: firstly, the categorization of problems mentioned above; and secondly, literary analysis of the CC protection and privacy problems within the categorization context. The key lessons gained during the study include verifying the decisive position played by consumer protection and privacy technologies in the implementation of CCs; recognising the various flaws, risks and attacks; and recognising tests. Furthermore, the sheer number of confidence references (as regards both challenges and solutions) revealed that CC plays a major role in confidence. In this paper, we are proposed a secure cloud storage access mechanisms based on polling or getting user access based on game theory. Here for protecting data we use cryptographic mechanism.
