After studying the secret sharing techniques based on symmetric bi-variate polynomial,a fully decentralized Ad-hoc network key management scheme is proposed.T nodes met the threshold conditions can set up network without any trust dealer.A new node can join the network any time without interactive of online nodes,and it also can acquire the same ability as the initial nodes and its private key after joining the network.The scheme firstly proposes using Newton polynomial interpolation in the process of key management in Ad-hoc networks,which improve the efficiency of the key management.
