群签名在处理身份验证和隐私相关问题时具有非常高的效率.群签名在安全应用和安全服务中,作为一种基本的黑盒方法,其广泛应用于电子现金系统和自动检售票系统.但仅依靠理论计算就认定群签名具有高效性是不科学的,必须要通过实际实验去验证其是否具有高效性.分别对基于配对的群签名和非配对群签名这2种群签名方案进行了实现,然后在笔记本电脑和2种型号的Android智能手机上进行了性能测试.通过对收集到的数据进行比较,以求分析最优方案.同时还希望通过这次实验获取的宝贵数据,能够分析出群签名方法应用在移动设备上时,其性能会受到哪些因素的影响.%Group signature is very efficient in dealing with authentication and privacy related problems.As a kind of basic black box method, group signature is widely used in electronic cash system and automatic ticket checking system.However, it is not scientific to determine the efficiency of group signature on the basis of theoretical calculation,so it is necessary to verify the validity of the group signature through practical experiment.The 2 group signature schemes based on pairing group signature and non group signature are implemented,and then the performance of the proposed algorithm is tested on the notebook computer and the Android smart phones of the 2 models.By comparing the collected data in order to analyze the optimal scheme.At the same time, we hope that the valuable data obtained from this experiment can be used to analyze the factors that affect the performance of group signature method when it is applied to mobile devices.
