摘　　要：当前可信光网络数据库匿名共享方法资源占有率平均值高,资源安全性能识别能力低,故提出一种新的基于区块链技术的可信光网络数据库匿名共享方法。采用位置匿名变换法计算区域内的匿名空间和临近的隐私节点,将在区域内服务器查询范围位置集合,通过该集合的查询节点向匿名用户反馈隐私变换准确率。建设新的节点资源库与链路通信,根据节点的数量与匿名资源的所属类型判断该资源能否在相应的网络资源中达成共识状态。利用区块链向新共享资源数据发送测试包,记录数据的经过途径与传输过程,判断信息的可信程度与安全性。实验结果表明,基于区块链技术的可信光网络数据库匿名共享方法有效降低了可信光网络数据库匿名共享方法资源占有率平均值,加强了资源安全性能识别能力。At present,the anonymous sharing method for trusted optical network database has high average resource occupancy rate and low identification ability of resource security performance,so a new trusted optical network database anonymous sharing method based on blockchain technology is proposed.The location anonymous transformation method is used to calculate the anonymous space and adjacent privacy nodes within the region.The locations of server query range within the region are gathered together.The gathered query nodes are used to feed back the privacy transformation accuracy rate to the anonymous users.New node resource library and link communication are built.Whether the resources can reach a consensus state in the corresponding network resources can be judged according to the number of nodes and the type of anonymous resources.The blockchain is utilized to send test package to the new shared resource data,so as to record the data path and transmission process and judge the credibility and security of information.The experimental results show that the trusted optical network database anonymous sharing method based on blockchain technology can effectively reduce its average value of resource occupancy rate,and strengthen the identification ability of resource security.
