通过对信息安全系统中常用的伪随机数生成算法及其随机性进行分析，比较了不同的伪随机数生成算法实现的优缺点。在此基础上提出了一种将VisualC＋＋中伪随机数生成机制与线性反馈移位寄存器结合起来产生随机数的改进方案，通过数值模拟和对比分析表明，改进方案具有较好的计算性能和随机性。

Aiming at studying pseudo-random number generation algorithm, which is commonly used in information se- curity system, the advantages and disadvantages of different pseudo-random number generation algorithms are compared and the typical pseudo-randomness of random number generation algorithm is analyzed. Combined the visual C++ in a pseudo- random number generator mechanism with a linear feedback shift register, an improved algorithm is proposed to generate ran- dom numbers. The numerical simulation and comparative analysis results show that the improvement algorithm has a good computing performance and randomness.
