摘要： 针对现有信任模型中信任搜索算法不能准确有效地对信任进行搜索与合成，利用主观逻辑理论对信任进行量化与计算，提出基于主观逻辑的信任搜索算法。算法由两个关键技术组成：信任路径提取算法与信任路径合成算法。仿真实例验证了该算法在信任合成时减少了信任网络中冗余信息对信任合成的影响，提高了信任搜索效率，使得合成结果更加准确。

Abstract: The trust search algorithm in the current trust models can not search and combine trust effectively and exactly. This paper uses subjective logic theory to quantify and compute trust, develops a new trust search algorithm based on subjective logic which is composed of an algorithm of obtaining trust paths and an algorithm of combination of trust paths. According to the experimental results, the algorithm makes the search of trust information effective, reduces the bad effect caused by redundant information, and makes the combination exact.

Key words: subjective logic, trust path, combination of trust
