提出了一种基于鼠标轨迹的真随机数产生器,并对该类产生器的优缺点、总体设计和基本技术进行了研究.为了消除相同用户鼠标轨迹中存在的相似性,利用混沌系统的敏感性,分别采用图像加密算法和Hash函数两种方法对鼠标轨迹进行后处理.大量严格的测试和实验表明,改进的基于混沌Hash函数的真随机数产生器具有安全、快速、方便和廉价的优点,可以在个人电脑上实际使用.
This paper presents a real-time random number generator based on mouse trajectory, and studies the advantages, disadvantages, overall design and basic techniques of this kind of generator.In order to eliminate the similarities existing in the trajectory of the same user, the chaos system is used The two methods of image encryption and Hash function are used respectively to postprocess the mouse trajectory.Many rigorous tests and experiments show that the improved real random number generator based on chaos Hash function has the advantages of safety, speed, convenience and low cost , Can be actually used on a personal computer.
