英文摘要：

This paper proposes a cloud computing environment based on particle to identify tree algorithm hybrid variety Trojan detection method. According to the related theory, the particle swarm of Trojan cloud computing environment for effective classification processing, which provide data for various Trojan detection based. Establish particles to identify tree, complete hybrid variety Trojan group of cloud computing environment detection. The experimental results show that the algorithm presented in this paper for hybrid variety Trojan detection of cloud computing environment can effectively improve the efficiency of detection, lower miss rate, thus providing security for the network security.
