摘　　要：采用目前方法在网络中进行安全威胁信息交换时,无法消除网络中存在的噪声,导致信息交换易受到噪声的影响,方法存在存储效率低、安全性差和合约开销大的问题。提出基于区块链技术的网络安全威胁信息交换方法,利用判别器和生成器构建DCGAN结构,采用DCGAN结构对网络信息进行去噪处理,避免噪声对网络安全威胁信息交换产生影响。采用区块链技术利用去噪后的网络信息构建网络安全威胁信息交换模型,利用上述模型在网络中完成安全威胁信息的交换。仿真结果表明,所提方法的存储效率高、安全性好、合约开销小。When exchanging threat information in the network, some methods are unable to remove noise, and the information exchange is susceptible to noise, leading to the problems of low storage efficiency, weak security and high protocol overhead. In this paper, a method to exchange threat information in cyber security based on blockchain technology was proposed. At first, a discriminator and a generator were used to construct a DCGAN structure. And then the DCGAN structure was used to remove noises in network information and to prevent noise from affecting the threat information exchange. Moreover, blockchain technology was combined with denoised network information to construct a model of exchanging threat information in cyber security. Based on this model, the exchange of threat information in cyber security was completed. Simulation results show that the proposed method has high storage efficiency, good security, and low protocol overhead.
