This paper puts forward a key strategy based on dynamic multipath distribution and adjacent nodes direct certification which is applied to protect network security. Experimental results show that the security of mechanism of dual-path based secret key distribution is better than mechanism of single-path secret-key distribution obviously. For the mechanism of single-path secret key distribution, the probability of key captured have a linear relationship with product of hops and the probability of unsafe node in network while it is only a linear relationship with the square of the numbers of the network nodes for the mechanism of dual-path. With the increasing of probability of unsafe, the safety performance gap of the two mechanisms is narrowing.
