Resource allocation policy based on trust in the multi-cloud environment

Cloud computing is growing rapidly due to its features of low cost, space saving, sharing etc., yet security issues are still a major concern. Multi-cloud computing technology was developed, in part, to address security concerns. One technique could use the Shamir's secret sharing method which is based on risk diversification. This work offers a solution strategy allowing users to allocate their resources to different cloud providers. In addition, we use trust values to measure a user's security when using cloud providers. Such values are used in contrast to the risk that user's resources may be leaked. The strategy is to find an appropriate plan whose trust value, from the user's perspective, is maximized by using a genetic algorithm. Experimental results indicate that the proposed solution strategy is effective and efficient.
