Key management scheme for providing the confidentiality in mobile multicast
Jong‐hyuk Roh, Kyoon-Ha Lee · 2006 8th International Conference Advanced Communication Technology · 2006
For successfully deploying many multicast service in the mobile environment, security infrastructures must be developed that manage the keys needed to provide access control to content. In this paper, we propose two methods for designing the key management scheme for the mobile multicast environment. The proposed schemes match the key management tree to the mobile multicast environment for localizing the delivery of the rekeying messages, reducing the communication costs, and solving the handoff problem in wireless region.
