Research on cloud Security defense strategy and security technology evaluation based on game theory

Yunnan University of Finance and Economics Chen

Firstly, this paper summarizes the application of game theory to user trust, Security Strategy optimization and security technology evaluation through literature review, and then summarizes the related theories of cloud computing. Then, according to the characteristics of cloud computing environment, we set up the game model from the two aspects of the user's game strategy and security technology evaluation, and put forward the game strategy of cloud service provider and the suggestion of system security. The specific research ideas and work contents are as follows: 1. To abstract the attack and defense between cloud end users and cloud service providers as incomplete information dynamic game, a dynamic game model of incomplete information is established from the security strategy based on game and the evaluation of the security technology of the system in two aspects. 2. Based on the game model of security attack and defense strategy, the paper studies the problem of cloud security from attack-defense model and repeated attack-defense model, and finally obtains relevant equilibrium state and strategy analysis. 3. Analyze the security evaluation model composed of cloud service provider, non-credit user and Intrusion detection system (IDS), and introduce the concept of repeated games to analyze the model in a multi-stage dynamic game. 4. The safety evaluation model is simulated and analyzed.
