摘要
针对自动信任协商的协商效率问题,提出了一种基于多样化历史信息的自动信任协商策略。本策略将历史信息作用于协商过程中,利用策略有向图来完成协商;利用票证来存储历史协商信息,并采用数字签名技术来保证信息的真实性和完整性。根据历史协商信息在产生方式上的不同,提出了信任票证和历史票证,并结合其特点设计了相关的格式以及验证和工作过程。最后进行了实验仿真,结果表明该模型可以提高重复协商的效率。
For the problem of efficiency which appeares in the repeated automated trust negotiation,a negotiation strategy based on diverse history negotiation information was proposed.This strategy combines history information with negotiation by means of policy directed graph and ticket.The former one is used to finish the negotiation and the latter one is used to storage history negotiation information,meanwhile,digital signature technology is adopted to ensure the authenticity and integrity of the information.According to the different modes of history negotiation which is generated,trust-ticket and history-ticket were proposed.In addition,proper formation,verification and working procedure were designed in view of their characteristics.Finally,simulation results demonstrate that this model can improve efficiency in repeated negotiation.
