摘要:

为解决因通信网络加密执行能力有限而造成的隐私信息识别异常问题，提升网络体系对于隐私文本的加密处理能力，设计基于区块链的通信网络节点位置隐私加密控制模型。在区块链技术的支持下，建立密码共识机制，再根据智能合约中协议条文的编码形式，求解节点加密差值，完成基于区块链的通信网络节点加密验证。按照信息序列定义条件，建立P盒、S盒两类信息数列处理结构，完成对通信网络节点位置隐私信息数列产生器的设计。规范隐私信息的数据帧格式，根据密钥内容查询结果，确定熵值控制系数的取值范围，再实施熵值校验处理，实现基于区块链的通信网络节点位置隐私加密控制模型的设计。实验结果表明，区块链技术作用下，通信网络在单位时间内所能加密处理的信息样本总量达到了9.8×1013bit，因加密执行能力有限造成的隐私信息识别异常问题得到较好解决，能够加强网络体系在加密处理隐私文本方面的能力。

Abstract:

In order to solve the problem of abnormal identification of privacy information caused by the limited implementation capacity of communication network encryption, and improve the network system's ability to encrypt private texts, a communication network node location privacy encryption control model based on the blockchain is designed. With the support of blockchain technology, establish a password consensus mechanism, and then solve the node encryption difference according to the encoding form of the protocol clauses in the smart contract to complete the encryption verification of communication network nodes based on the blockchain. According to the definition conditions of information sequence, two kinds of information sequence processing structures, P box and S box, are established to complete the design of privacy information sequence generator for communication network node location. Standardize the data frame format of privacy information, determine the value range of entropy control coefficient according to the query result of key content, and then implement entropy verification processing to achieve the design of the location privacy encryption control model of communication network nodes based on the blockchain. The experimental results show that under the effect of blockchain technology, the total number of information samples that can be encrypted and processed by the communication network in a unit time reaches 9.8 × 1013bit, the problem of privacy information identification exception caused by the limited encryption execution ability has been well solved, which can strengthen the network system's ability to encrypt and process private text.
