Abstract

The invention discloses an information security management and control method under a cloud manufacturing environment. On the basis of a network security protocol, a password technology and a public key infrastructure (PKI), comprehensive security guarantee is supplied to information interaction among cloud internal networks, between one cloud and another cloud, and between a user and each cloud by using implementation technologies and methods, such as a virtual private network (VPN) based on multiple layers of protocols, a digital envelope and a password algorithm; Intranet, Extranet and Internet of a cloud manufacturing system are covered; comprehensive management and control technical information files are stored and transmitted to each used loop; a session key (SK) which is randomly produced by using a key production protocol is used for symmetrically encrypting the technical information files; and a receiver public key obtained according to a PKI digital certificate asymmetrically encrypts the SK to form the digital envelope for protecting the technical information files and the SK. The information security management and control method has the characteristics of being high in confidentiality, high inefficiency, flexible in arrangement and the like and can be widely applied to the cloud manufacturing system and other network manufacturing systems.

Description

[0001] technical field [0002] The present invention relates to an information security management and control method in a cloud manufacturing environment, and specifically refers to a method for user-oriented collaborative information security interaction and sharing under a cloud manufacturing mode established through a multi-layer security communication protocol, cryptographic technology and public key infrastructure PKI . The invention belongs to the technical field of distributed manufacturing system information integration. technical background [0003] With the rapid development of information technology and computer network technology, a batch of cross-enterprise, cross-regional and even cross-border collaborative processing and manufacturing industries have emerged, and have gradually become one of the important components of my country's manufacturing industry. However, due to the lack of an effective resource sharing service platform and collaborative support me...
