摘要: 针对神经密码同步速度慢的问题,基于树形奇偶机(TPM),提出修改权值的新规则,在同步过程中设置队列用来记录每次通信的结果,实时估计两个互相通信的树形奇偶机的同步程度,并根据估计的结果决定权值修改幅度,在同步程度较低时适当增大权值修改量,在同步程度较高时适当减小权值修改量。仿真实验结果表明,应用新学习规则后同步效率提高了80%以上,同时与几种经典学习规则相比,计算开销更小,安全性得到进一步提高。

Abstract: To solve the low speed of synchronization, a new learning rule was proposed by employing Tree Parity Machine (TPM). By setting queues to record the results of each communication in the synchronization process, this rule estimated the degree of synchronization of the two TPMs communicating with each other in real time. According to the results of estimation, the rule selected appropriate values to modify the weights, appropriately increased weight modifications in the lower degree of synchronization and reduced weight modifications in the higher degree of synchronization. Finally, the simulation results show that synchronization efficiency is improved more than 80% by applying new learning rule. Meanwhile, it is also indicated that the rule is computationally inexpensive and it improves the security of communication compared to the classic learning rules.
