摘要 近年来,随着科技的飞速发展,高科技犯罪也愈加普遍,但目前还没有基于信息技术下追捕罪犯方法的研究。为了解决上述问题,提出了一个警察抓小偷的模型并对模型进行了分析,然后针对该模型提出了一个基于无证书广播签密技术的方案,并对其进行了安全性分析和性能分析。该方案可抵抗恶意且被动的KGC攻击,保证了数据的机密性和认证性,无需双线性对操作,简单高效。 With the rapid development of science and technology,high-tech crime has increased quickly in recent years. Up to this time,there is limited research on the method of capturing crime based on information technology. In order to address this problem,a scheme based on certificateless broadcast signcryption is proposed in this paper. The scheme can resist malicious-but-passive key generation center( KGC) attacks,and ensure the confidentiality and authentication of data. As this scheme eliminates bilinear pairing operation,it is simple and efficient.
