本课题实现的是基于随机化回答的网上调查系统。为了保护用户的隐私,采用的是双向无记忆传输技术,调查人员并不知道被调查者的真实想法。加密算法采用离散对数实现,要想对一个很大的质数求解其离散对数是一个复杂的过程,破解密码需要一段很长的时间,期间传输的数据是安全的。在课题的实现过程中,我用一台电脑简单的模拟了一个调查对多个被调查者的调查,核心的算法及其功能都已实现。调查者,被调查者的功能都通过函数实现,调查者和被调查者之间的数据通过函数间的变量名传递。
This topic is based on the randomized online survey system. In order to protect the privacy of users, using two-way memoryless transmission technology, the investigators did not know the respondents’ real thoughts. Encryption algorithm using discrete logarithm, to solve a large number of primes of discrete logarithm is a complex process, crack the password for a long time, during the transmission of data is safe. In the realization of the subject, I used a computer to simulate a survey of multiple respondents a simple survey, the core algorithm and its functions have been achieved. The functions of the investigator and the respondent are all realized through the function, and the data between the investigator and the respondent is transmitted through the variable names among the functions.
