基于区块链的自组织网络多信道访问控制仿真

摘要
为了提高自组织网络的安全性和可靠性,需要研究自组织网络多信道访问控制方法。采用当前方法对自组织网络多信道进行访问控制时,数据在信道传输过程中容易被篡改和伪造,用户身份认证结果与实际不符,存在数据完整度低和身份认证准确率低的问题。提出基于区块链的自组织网络多信道访问控制方法,利用区块链技术采集自组织网络节点中存在的数据,对数据做加密处理,并将加密处理后的数据传送到数据采集基站中,利用共识算法将基站中的数据拷贝到公共的数据库中,完成数据的加密存储,通过新用户授权机制、用户吊销机制和文件访问机制完成自组织网络多信道的访问控制。仿真实验结果表明,所提方法的数据完整度高、身份认证准确率高。
In order to improve the security and reliability of ad hoc network, it is necessary to research the method of multi-channel access control of ad hoc network. In this paper, a method of multi-channel access control based on blockchain was proposed. The blockchain technology was used to collect the data in the nodes of ad hoc network and then encrypt the data. Meanwhile, the encrypted data were transmitted to the data acquisition base station. The consensus algorithm was used to copy data of base station into a public database, so as to complete data encrypted storage. Finally, the new user authorization mechanism, the user revocation mechanism and the file access mechanism were used to complete the multi-channel access control of ad hoc network. Simulation results prove that the proposed method has high data integrity and high authentication accuracy.
