在通信量较大时,传统数字化档案信息安全防护算法受到外界窃取攻击后,会造成通信过程产生较大时延,并降低通信流量速率,针对此问题设计了一种基于量子密码的数字化档案信息安全防护算法。在量子密码学的基础上,将量子比特变换应用在通信协议中,利用Hadamard门和量子受控非门作为通信协议的传输机制,设计安全编码方案网络拓扑结构,确定其中主干信道的容量,利用幺正操作改变粒子形态,实现安全编码,最后规范分发量子密钥过程,优化TLS通信安全连接,实现安全防护算法密码体制的优化。在仿真分析中,设计的算法与传统算法进行测试比较,结果表明,设计算法的网络延时更低,通信流量速率更高,验证了算法的有效性。

When the communication volume is large, the traditional digital archive information security protection algorithm will be attacked by external theft, which will cause a large delay in the communication process and reduce the communication traffic rate. Therefore, a digital archive information security protection algorithm based on quantum cryptography is designed. On the basis of quantum cryptography, quantum bit transformation applied in the communication protocol, using Hadamard gate and quantum controlled not gate as a transport mechanism, the communication protocol designs security coding scheme network topology structure, determines the capacity of the main channel, using the unitary operation to change particle morphology and implements security coding, then quantum key distribution process final specification is realized.TLS communication security connection is optimized, realizing the optimization of security protection algorithm password system. In the simulation analysis, the designed algorithm and the traditional algorithm are tested together. The results show that the designed algorithm has lower network delay and higher traffic rate, which verifies the effectiveness of the algorithm.
