Creating Secure Clouds by Continuous Auditing Using Block Chain

The cloud computing infrastructure category has major advantages in the handling of user data. Yet it also causes other security issues including honesty of the records. Public verification procedures that require a customer to select a third-party auditor to verify the customer's data validity, because existing public verification systems are dangerous for procrastinating auditors that might conflict with the verification phase. Public key infrastructure (PKI) is used to develop most identity authentication systems, and it suffers from the issue of certificate management. Via the use of block chain technologies we suggest the first certificate-less public authentication scheme against procrastinating auditors (CPVPA). The core theory is that auditors are expected to report any inspection result as a transaction into a series of blocks. Because transactions on the block chain are time-sensitive, it is possible to time-stamp the validation before the actual transaction is recorded in the block chain, enabling users to ensure whether auditors conduct the verifications within the stated timeframe. In addition, CPVPA is based on certificate-free cryptography and free from issues in the administration of certificates. CPVPA security is shown by consistent evidence of compliance and a rigorous performance review is done to demonstrate that CPVPA is a success.
