基于主观逻辑的区块链信息能力评估信任模型

分析了区块链的技术特点和工作原理,结合分布式网络节点,参考信息能力评估体系,研究这些方法的实现原理、复杂性,总结其合适的环境和优缺点,提出了基于主观逻辑的区块链信息能力评估信任模型(ETMBCIC-SL).该模型引入Jøsang的主观逻辑来检测区块链记账行为,以解决检测区块链权限控制的动态可信问题,通过独立观点和依赖观点2个方面检测信息能力.仿真结果表明,该模型具有较高的完备性、准确性和实时性.

Evaluation trust model of block chain information capacity based on subjective logic

The technical characteristics and working principle of block chain are analyzed,combining with distributed network nodes and refering to information capability evaluation system.By studing the implementation principle and complexity of these methods,this work summarizes their suitable environment and advantages and disadvantages,and proposes a evaluation trust model of block chain information capacity based on subjective logic(ETMBCIC-SL).This model introduces Jφsangs Subjective Logic to detect the block chain accounting behavior,to solve the dynamic trustworthiness problem of the block chains privilege control,and to dynamically detect the block chain privilege control through independent viewpoint and dependent viewpoint.The simulation results show that the model has high completeness,accuracy and instantaneity.
