This paper analyzes the traditional anonymous roaming authentication protocol

and pointed out the deficiencies of their anonymity is not controlled and the communication is delay.The controllable anonymous roaming authentication protocol proposed in this paper for heterogeneous wireless networks

which can be completed to verify the legitimacy of the identity of the mobile terminal through a message interaction.If the mobile terminal has malicious operation

the home network authentication server can help remote network authentication server to revoke the identity anonymity of the mobile terminal.This is a protocol in anonymous authentication

at the same time

and which effectively preventing the occurrence of malicious behavior

and the communication delay.This protocol is safe in the CK security model.
