基于改进型树型奇偶机的密钥交换研究OACSTPCD

This paper proposes a key exchange method based on improved tree parity machine.The pseudo-random number generator is used to generate common input vectors for both sides of communication,so as to reduce the amount of data needed in network synchronization.Sliding window based learning rules are used to dynamically change the learning rate,so as to reduce the number of synchronization.Furthermore,an efficient input sequence generation method based on knapsack algorithm and depth first search traversal algorithm is proposed to increase the positive learning probability and accelerate the synchronization speed.The sim-ulation results show that the communication data volume of the improved model is reduced by more than 60%,and the synchroniza-tion time is significantly reduced.
