Mobile proxy safety route method based on group signature

The mobile agent safety route method based on group signature in computer application technology field comprises: with group signature mechanism, managing a plurality of hosts and optimizing key allocation; endowing some initial trust degree for every host by mobile agent owner to classify host and decide visit order for said trust degree into some group; in practical movement, sending the mobile agent to some group member in the first group by said owner; after selecting the next visited host by SelectNextHost algorithm, moving with Sending algorithm by current host the agent to the object for receiving agent with Receiving algorithm; for DoS attack, tacking the attacking host by group signature to reassign trust degree and optimize group structure. This invention can reduce DoS attack probability and guarantees security of mobile agent.
