摘要
In the manufacturing grid environment, the span of the consideration of security issues is more extensive, and the solutions for them are more complex, therefore these problems in manufacturing grid can＇t longer be addressed by existing security technologies. In order to solve this problem, the paper first puts forward the security architecture of manufacturing grid on the basis of the proposal of the security strategies for manufacturing grid; then the paper introduces key technologies based on public key infrastructure-certificate authority （PKI/CA） to ensure the security of manufacturing grid, such as single sign-on, security proxy, independent authentication and so on. Schemes discussed in the paper have some values to settle security problems in the manufacturing grid environment.
