Multi-level Security Task Scheduling Scheme Based on Task Priority
Abstract:
Data security is a primary consideration when users choose cloud storage, and it is also an important factor that hinders the development of cloud storage. In order to meet the requirements of secure storage of user-differentiated data and guarantee a good user service experience, we propose a multi-level security task scheduling scheme that comprehensively considers the data security level, user service level, and task waiting time. The scheme adopts the idea of multi-level security. The security requirements of different security level data are ensured by the key strength of the cryptographic algorithm. The mapping between the data security level and the key length under the selected cryptographic algorithm achieves the task's priority order. Scheduling appropriate encryption modules to implement differentiated encryption is suitable for cloud storage environments where data sensitivity and importance are diversified.
