移动云计算中基于动态博弈和可靠推荐的传递信誉机制

Dynamic game and reliable recommendation based transferring reputation mechanism for mobile cloud computing

移动互联网和云计算的蓬勃发展,涌现出了大量基于移动云平台的服务。用户在使用移动云服务的同时,也将大量用户数据和隐私信息存放在云端,面临日益严重的数据泄露和隐私暴露等安全威胁。以移动云计算中的数据安全和隐私保护为研究背景,针对内部诽谤攻击和移动攻击,首先提出基于动态博弈的推荐激励策略;然后结合该策略,建立可靠推荐信誉评估模型;最后,提出一种新的基于动态博弈和可靠推荐的传递信誉机制。仿真结果表明,所提传递信誉机制能有效地抵御内部诽谤攻击和移动攻击,增强移动终端的可信性,进而提高移动云服务的数据安全和隐私保护。

The booming development of the mobile internet and cloud computing leads to the emerging of many mobile cloud platforms based services. However, since mobile users store lots of data and privacy information in the cloud when they are using the mobile cloud services, they are facing multiple increasingly serious security threats such as data leaks and privacy exposures. The data security and privacy protection was investigated in mobile cloud computing, aiming at the internal bad mouthing attacks and mobile attacks. A dynamic game and reliable recommendation based transferring reputation mechanism was proposed. First, a dynamic game based recommendation incentive mechanism was proposed. Secondly, a reliable recommendation reputation evaluation model was established based on the incentive mechanism. Last, a novel transferring reputation mechanism was proposed that combined the above mentioned incentive mechanism and reputation evaluation model. Simulation results demonstrate the proposed transferring reputation mechanism can defend against the internal bad mouthing attacks and mobile attacks effectively, enhance the credibility of mobile terminals and improve the data security and privacy protection of mobile cloud services.
