ASP网络化制造协同设计安全研究

Research on the security of collaborative design in networked manufacturing based on ASP

中小企业在我国经济发展中占据重要位置。在全球化经济背景下,根据中小企业现状,政府提出建立不同行业的ASP平台,以促进中小企业的信息化。本文针对面向中小企业ASP网络化制造平台的协同设计安全问题,提出一套完整的安全保护策略。首先对不同ASP客户进行不同策略的身份认证,采用了动态口令与令牌相结合的方式确保客户的合法性;其次在机械产品协同设计过程中,采取盟主统筹、盟主负责的总体方案,同时对设计过程进行基于角色的访问控制;最后创造性的对设计数据进行数字签名保护,使知识产权不受侵犯。

Small and Medium-sized Enterprises （SMEs） take important rolls in the economic development of China. According to the realities of SMEs, different kinds of ASP platforms for different industries are proposed by the government to accelerate IT application in SMEs. This paper gives an integrated security strategy of information protection for collaborative design in networked manufacturing based on ASP platform for SMEs. Firstly, a multi-secure authentication strategy is developed for different clients, and dynamic passwords combined with tokens are used to ensure the validity, Then a mode, in which the alliance leader managed the whole mechanical design process, is proposed, and rule based access control mechanism was applied in the design process. Finally, digital signature technology is creatively used to protect the copyright of the design data.
