Abstract:

A survey of many kinds of schemes was present about secure multicast key management. In the meanwhile, in view of mobile environment, frequent handoff and poor reliability are the key properties and differences. Thus the secure multicast key management strategy in mobile Internet was discussed deeply in the survey.

Key words: IP multicast, key management, mobile Internet, RingNet hierarchy
