ABSTRACT

The mobile environment has problems that more packet loss is incurred caused by a MH's handoff. So existing loss tolerate multicast authentication schemes are able to apply in mobile multicast However, we should consider low computation resources and battery constraints for mobile multicast. Thus, we propose lightweight and simple authentication mechanism for real-time service over mobile multicast. The proposed mechanism is able to endure allowed packet loss caused by network instability and handoff of the MH. In section 2, we discuss pervious studies for authentication mechanism and mobile multicast, and we propose our mechanism in section 3. Finally, section 4 describes conclusion.
