A Big Data Encryption Method Based on New True Random Number Generator

为了解决大数据安全性不足的问题,在现场可编程门列阵的基础上,设计了一种融合了链式振荡环、触发器阵列以及异或门阵列的改进大数据加密方法。然后通过与L8M-LBE、R2S-LBE进行对比实验的方式对该方法进行验证。实验结果表明,改进加密方法的NIST测试通过率为97.5%,优于传统真随机数发生器。在加密硬件吞吐率测试方面,改进加密方法的吞吐率为1983.3 Mbps,优于L8M-LBE与R2S-LBE。实验结果证明改进后的真随机数发生器加密性能得到了极高的提升,能够为大数据加密安全提供一个新的思路。

In order to solve the problem of insufficient big data security,an improved big data encryption method based on field programmable gate array is proposed,which integrates chain oscillation ring,trigger array and XOR gate array.Then the method is verified by comparing with L8M-LBE and R2S-LBE.The experimental results show that the NIST test pass rate of the improved encryption method is 97.5%,which is better than the traditional true random number generator.In terms of encryption hardware throughput test,the throughput of the improved encryption method is 1983.3 Mbps,which is better than L8M-LBE and R2S-LBE.The experimental results show that the encryption performance of the improved true random number generator has been greatly improved,which can provide a new idea for big data encryption security.
