Evaluating trust degree of Web services with the method of neural network from the aspect of trust history sequence is proposed. The principle of the method, applicable neural network structure, neural network construc ting, input standardization, training sample constructing, and the procedure of evaluating trust degree of Web services with trained neural network are described. Experiments show that it is feasible and effective to evaluate trust degree of Web Service with neural network.展开更多

Owing to avoiding the heavy computational demands the public key cryptography operations bring about, the authentication protocol is well-suited for security authentication on the Web.展开更多
基于信任的网络交易业务日益增多,然而Web服务环境下的信任评估模型还不健全,存在Web服务请求方身份不明、信任度量因素考虑不周全及信任评估主观性强等问题。针对上述问题,提出了一种Web服务环境下信任增强的综合评估模型——WS-TECEM(...基于信任的网络交易业务日益增多,然而Web服务环境下的信任评估模型还不健全,存在Web服务请求方身份不明、信任度量因素考虑不周全及信任评估主观性强等问题。针对上述问题,提出了一种Web服务环境下信任增强的综合评估模型——WS-TECEM(Trust Enhanced Comprehensive Evaluation Model for Web Services)。WS-TECEM在传统模型的基础上,引入信任关系强度、第一手、第二手、第三手信誉看法及第三方信誉推荐者的可信度等思想,提出一种信任粒度更细、信任指数更强的评估模型,仿真实验表明,WS-TECEM能更全面、更准确地度量Web服务环境下交互双方的可信度。展开更多
