the character that the Trojans use domain name to control was analyzed and the method that DNS adopted to detect Trojans was introduced. Secondly
based on the analysis of static and dynamic characters for Trojan domain name
eight indicators were obtained as the input of BP neural network algorithm
including operation time of domain name
the period to visit the domain name
the variation speed of IP address
the country change of IP address
IP address of private address
the same domain name with multiple IP address for different countries
TTL value and search times of domain name. An improved BP neural network algorithm was proposed to solve training efficiency for a great number of domain names
and large average error. Finally
the experimental evaluation of samples was tested by improved neural network algorithm. Compared with traditional neural network algorithm
the detection efficiency is better.
