Analysis of Propagation Characteristics of Variant Worms

摘要

The large-scale spread of Internet worm will stimulate users' awareness of security to deploy defense strategy against worms. The game between users' response time and worms' propagation speed affects the range of infection. The paper provides a new kind of worm called "variant worm" which can mutate itself into new forms to implement a secondary propagation. We analyze the necessary conditions of secondary propagation and the propagation characteristics of variant worm in theory.
