A Defense Model against Mobile Phone Malicious Codes Based on Social Computing

摘要

With the convergence of mobile communication network and Internet in depth,mobile Internet is penetrating into every field of people's life. Smart phone bring us great convenience,but it also becomes the breeding ground for the spread of malicious codes. In this paper,we propose a trust transfer algorithm based on the ant colony optimization algorithm to calculate the trust degree between any two nodes in the social network. Afterwards,a defense model based on social computing is presented for mobile phone malware. The simulation results show that our trust transfer algorithm improves the computation accuracy of indirect trust value by 14.65% compared with the Tidal Trust algorithm,and the patch transmission speed of our model is faster than that of others.
