【摘要】：随着科技的发展,移动终端所具备的功能越来越完善,与此同时,在移动终端上的各种安全及隐私问题也逐渐暴露出来。在移动终端上,采取身份认证等的措施可以有效得解决相关信息安全问题,以保证数据的安全性以及可靠性。数字签名技术是实现身份认证的一种技术,可以解决伪造、篡改、冒充、抵赖等问题,而且具有高安全性。数字签名的研究已经逐步深入,应用于多种场景,本文着重研究在移动终端上的数字签名。本文针对移动终端,在研究了移动终端特征的基础上,设计了移动特色数字签名方案,主要研究工作和创新点包括： 1.根据移动终端设备特征确定了以地理位置和移动设备信息为研究特点,研究设计了适用于移动终端的数字签名系统结构,优化了椭圆曲线密码体制实现过程的基本算法。 2.根据移动终端特点,在分别研究了地理位置信息和移动设备信息的基础上,将地理位置信息和移动设备信息与数字签名相结合起来,设计了移动特色数字签名方案,并分析论证了其正确性以及其具有高安全性。 3.根据移动数字签名系统结构,以及移动特色数字签名方案,实现了移动数字签名的客户端。客户端的内容模块分为接入验证,数字签名和验证,数据加密和解密这三个部分。在数字签名、验证与数据加密、解密部分,在实现相应处理功能的基础上,本文针对不同文件类型做了相应的特殊设计与实现。
[Abstract]:With the development of science and technology, the functions of mobile terminals are becoming more and more perfect. At the same time, various security and privacy problems on mobile terminals are gradually exposed. Taking measures such as identity authentication can effectively solve the problem of information security in order to ensure the security and reliability of data. Digital signature technology is a kind of technology to realize identity authentication, which can solve the problem of forgery, tampering, impersonation, etc. The research of digital signature has been deepened and applied to many kinds of scenarios. This paper focuses on digital signature on mobile terminal. Based on the study of mobile terminal features, this paper designs a mobile signature scheme based on mobile terminal features. The main research work and innovations are as follows:. 1. According to the characteristics of mobile terminal equipment, the paper studies and designs the digital signature system structure suitable for mobile terminal, and optimizes the basic algorithm of realizing elliptic curve cryptosystem. 2. According to the characteristics of mobile terminal, based on the study of geographic location information and mobile device information, a mobile signature scheme is designed by combining geographic location information and mobile device information with digital signature. Its correctness and high security are analyzed and proved. 3. According to the structure of mobile digital signature system and the scheme of mobile digital signature, the client of mobile digital signature is realized. The content module of client is divided into access verification, digital signature and verification. Data encryption and decryption are three parts. In digital signature, verification and data encryption, decryption, on the basis of the corresponding processing function, this paper makes the corresponding special design and implementation for different file types.
