计算机信息安全中数据加密技术应用研究

Application of Data Encryption Technology in Computer Information Security

计算机信息在传递、处理和存储过程中极易被攻击,安全性得不到保证,因此提出计算机信息安全中数据加密技术的应用研究。以计算机信息作为目标,设计密钥流发生器,借助现场可编程逻辑门阵列(Field Programmable Gate Array,FPGA)硬件芯片划分密钥流发生器工作状态,合理规划加密工作流程。在此基础上,通过软件技术编写大素数搜寻函数,得到大素数后,由密钥流发生器生成初始密钥,并利用M序列和变换函数处理初始密钥和明文,完成对计算机信息的数据加密处理。实验结果表明,该技术比应用其他技术的计算机信息处理效率高,信息加解密处理前后损失极小,整体安全性更高。

Computer information is very easy to be attacked in the process of transmission, processing and storage, and the security cannot be guaranteed. Therefore, an application research of data encryption technology in computer information security is proposed. Taking the computer information as the goal, design the key stream generator, use the Field Programmable Gate Array(FPGA) hardware chip to divide the working state of the key stream generator, and reasonably plan the encryption workflow. After that, the initial key is generated by the key stream generator, and the initial key and plaintext are processed by the M sequence and the transformation function to complete the data encryption processing of the computer information. The experimental results show that this technology has higher information processing efficiency than other technologies, the loss before and after information encryption and decryption processing is extremely small, and the overall security is higher.
