Aiming at the potential security risks of technical information transmission,data sharing,identity authentication and access control in the networked manufacturing outsourcing process,a security control support system based on network security protocol design,Public Key Infrastructure(PKI)technology and cryptographic technology was puted forward to manage each link of technical information file's storage,transfer and use from three levels of transaction protocol,security authentication and encryption control.In this system,Internet Protocol Security(IPSec)and Secure Socket Layer(SSL)of the network security protocol were used respectively by enterprise trade agreement layer according to different trust degree.Through the digital certificate issued by CA certificate authority, the identity authentication and encryption key of security authentication layer was verified.Based on the session key generated randomly,the technical information file was encrypted by encryption control layer.The effectiveness and feasibility of proposed system was verified by the application cases.
