Directive Privacy-Preserving Scheme for Dense Service Intervals in Cloud Platforms
Cloud-based services are disseminated from heterogeneous service providers relying on user density and request allocation. The heterogeneous nature requires diverse security methods for user privacy-preserving. However, the privacy requirements are increasing the complexity without consistent security. For resolving this issue, a Directive Privacy-Preserving Scheme (DP2S) is introduced in this article. This scheme presents a synchronized end-to-end authentication for user request/ response intervals. In the active intervals, session keys are generated using a linear hash function for synchronized authentication. The process is valid until the last response is provided; the void response leads to session termination. In the further process, a new key is generated based on mutually agreed sharing time. This prevents session breakdowns, false rates and improves the response ratio.
