Abstract: Safe and efficient networking of embedded systems was the integration development bottleneck for the next generation of embedded systems and network systems. In conventional networking technology of embedded systems, either the network security or network efficiency was ignored, so a better performance cannot be achieved. An embedded dynamic security networking technology based on quick jump and trust was proposed, and the multiple network nodes based on a random beating of fast switching were used to achieve optimal network search. When the Web search was completed, the trust mechanisms were taken to protect the security of the network system access, while achieving rapid networking and security. A set of 10-node was used to test the system, the result shows that with quick jump and trust, the systems security risk distribution can be accurately detected, enabling secure network, so it is of good network system security application.

Key words: quick jump, trust, security networking, embedded system
