根据已有的底层安全策略结合制造业信息化现状给出了一个新的安全机制。主要思想是:借用新开发的CIP Safety协议自身的安全功能和其屏蔽底层网络异构性特性,通过把信息网分为两层,分层管理的两层防护方法来实现制造业信息化的底层信息安全。
According to the existing underlying security strategy combined with the status quo of manufacturing information, a new security mechanism is given. The main idea is to borrow the newly developed CIP Safety protocol’s own security function and the characteristics of shielding the heterogeneity of the bottom network, and to realize the bottom of the manufacturing informationization by dividing the information network into two layers and two layers of layered management methods information security.
