摘　　要：针对多云环境下用户的分布式拒绝服务攻击缺乏有效处理机制的现状,从云服务提供商收益角度出发,提出多云环境下基于博弈论的用户行为分析模型。模型首先基于博弈论构造收益矩阵,之后利用模糊隶属度函数判定用户的行为,并进一步评估非协作和协作场景下云服务提供商的资源消耗和收益。经仿真验证,协作模型能够在减少资源消耗的基础上,有效地降低云服务提供商遭受分布式拒绝服务攻击的风险,相对于非协作场景,可以将单位资源的收益提高3倍以上,具有很强的现实意义。Aiming at the situation of lacking research on Distributed Denial of Service （DDoS） attack under multi-clouds environment,a user behavior analysis model based on game theory under multi-clouds environment was proposed from the perspective of cloud service provider.The model firstly constructs a payoff matrix based on game theory,and then it judges user behavior through fuzzy membership function,and evaluates the resource consumption and profit of cloud service provider under non-cooperation and cooperation scenarios.Simulations show that the proposed cooperation model can reduce resource consumption,lower the risk of DDoS attack for cloud service providers,and prompt the profit of each resource unit for more than three times,which takes an effective significance.
