本文针对密码算法的输出序列进行随机性测试。我们借鉴软件工程学原理，首先以形式化方法对随机性测试过程进行分析，建立平台整体模型 其次根据随机性测试原理，采用系统化和模块化的方法，对随机性测试的方案进行了设计 接下来，根据所设计的方案实现了随机性测试系统，该系统集成了NIST随机性测试方法 最后，我们对AES和SMS4加密算法进行了实测对比和分析。在Linux操作系统中，我们生成了新的makefile文件，制作了RPM软件包，实现了测试平台在多系统中的方便使用。-In this paper, the output sequence of the cryptographic algorithm tests for randomness. We can learn software engineering principles, the first formal methods to analyze the randomness of the testing process, and to create a platform for the overall model　followed by systematic and modular approach based on the principle of randomness test, random test program design　 Next, according to the design of the program to achieve the the randomness test system, the system integrates the NIST randomness test methods　Finally, we carried out the encryption algorithm AES and SMS4 Found comparison and analysis. The Linux operating system, we generate a new makefile file produced RPM packages, the test platform in the multi-system easy to use.
