Modeling and Simulation of Secure Data Transmission in High-Speed Embedded Systems

针对当前隐私数据安全传输模型中,普遍存在着隐私数据传输送达率较低、内存消耗较大、丢包率较高等问题。提出基于容忍时延网络的隐私数据安全传输模型。通过对高速嵌入式系统中隐私数据用户身份验证进行检测,实现身份验证程序的导入,对系统用户隐私数据进行加密,对加密后的密文进行去噪声处理。在此基础之上,采用整数进行隐私数据多级加密;分析加密后隐私数据批量数据传输等待时间、单条数据传输等待时间的期望值和方差,将其带入切比雪夫不等式中得到数据传输送达率,依据传输送达构建高速嵌入式系统中隐私数据安全传输模型。实验结果表明,所提出模型隐私数据安全传输送达率较高、内存消耗较小、丢包率较低。

In the current secure transmission model of private data,the delivery rate of private data transmission is low. Meanwhile,the memory consumption and packet loss rate are high. Therefore,a model of secure transmission for private data based on delay-tolerant network was proposed. By detecting the user authentication of privacy data in high - speed embedded system,we successfully imported the authentication program. Then,we encrypted the user privacy data in system and removed the noise from the encrypted cipher text. On this basis,we applied integers into the multi - level encryption of privacy data. Moreover,we analyzed the expected values and variances of waiting time of batch data transmission and single data transmission of encrypted privacy data. After that,we brought them into Chebyshev inequality to calculate the delivery rate of data transmission. Based on transmission and delivery,the secure transmission model of privacy data in high - speed embedded system was constructed. Simulation results show that the proposed model has high transmission rate,low memory consumption and low packet loss rate during the secure transmission of privacy data.
