【摘要】 数字签名的基础理论研究进行了很多年，也取得了很多成果，但是面向网络化制造资源管理的数字签名技术还未深入研究。本文在贵州大学现代制造重点实验室关于网络化制造研究工作的基础上，分析了网络化制造资源管理系统的数据交换和传输特点，开展了数字签名技术的基本理论和算法的研究，将数字签名技术引入网络化制造资源管理系统，研究了数字签名技术在该系统中的应用模式，提出了面向网络化制造资源管理的多重有序数字签名方案。针对该方案的技术实现，本文改进了数字签名流程，建立了基于Hash函数的数字签名摘要算法；结合J2EE相关技术实现签名文件传输系统，保证了网络化制造中数据传输和电子交易的安全性、可靠性、完整性、保密性及不可抵赖性。论文对数字签名技术的国内外研究现状进行了调研和分析，针对网络化制造的资源管理需求，开展了相关数字签名关键技术的研究，构建了网络化制造资源管理中数字签名系统的总体构架；在数字签名技术及其理论、数字签名的密钥管理、网络化制造的数据交换和信息传输技术等方面开展研究工作，并在以上研究成果的基础上，建立了网络化制造资源管理系统中的数字签名子系统。更多还原

【Abstract】 The basic theories of digital signature have been researched for many years and got many productions, but which haven’t been researched for manufacturing resource management. Based on the foundation of the Guizhou modern manufacturing key laboratory for network manufacturing,the paper has analyzed the data exchange and the transmission characteristic of network manufacturing resource management system, developed the digital signature technology elementary theory andthe algorithm research.Then the paper studied the application pattern of digital signature technology in this system and proposed multiple ordinal digital signature plan face to the network manufacturing resource management by introducing the network manufacture resource management system thedigital signature technology in other domains success experiences. In view of this plan technical realization, this paper improved the digital signature flow,has established digital signature algorithm based on the Hash function , has realized the signature file transfer system utilizing the J2EE related technology. The secrecy, authentication, integrity and non-repudiation of data transmission and the electronic transaction security in the network manufacture are guaranteed.The paper has carried on the investigation and the analysis to the digital signature technology domestic and foreign research level .In view of network manufacturing resource management demand , the correlation digital signature essential technology researches have been carried out and the digital signature system overall skeleton has been constructed in the network manufacture resource management .Last, in foundation of the above research results , a digital signature subsystem has been established in the network manufacture resource management system .更多还原
