摘　　要：提出一种基于评分监管协议(RSP)的信誉机制。通过对自主元素服务信度及评分信度的区分刻画和动态关联,识别和惩罚不递交评分、虚假评分,激励自主元素积极参与、诚实评分,并给出RSP分布式的实现方法。仿真实验结果表明,含RSP的信誉机制能够实现自主元素基于评分可信性的差异化服务,有效抵制恶意攻击。A Rating-Supervised Protocol（RSP）-based reputation mechanism is presented. By depicting autonomic elements trust degree on service and on rating differently and associating them dynamically, the non-rating, malicious rating can be distinguished and punished. Meanwhile, autonomic elements are stimulated to participate actively and rate honestly. The distributed implementation is provided. Experimental results show this RSP-based reputation mechanism can realize the differential service based on ratin~ trustworthiness, and efficiently resist malicious attack.
