Research on service path configuration method based on shamir algorithm

A service path configuration method on shamir algorithm is advanced. The data path information is distributed and verified to do the test and verify the service chain deployment through the packet in message of Openflow. First, the path verification identification is generated according to the polynomial shamir sharing algorithm. And then with the distribution of service chain deployment, the controller distributes the control verification flow table. When the service traffic passes through the configuration switch, the path verification message will be uploaded, and the controller will carry out the verification and decision judgment. Finally, the experiment shows the correctness and security of the method.
