Key Establishment and Management for Secure Cellular Machine-to-Machine Communication

M2M(Machine-to-Machine) communication is considered to be one of the major issues in future network. Especially, M2M will bring various benefits in wireless communications when it is interconnected with cellular network. Considering the characteristics of cellular M2M network, traditional security solutions are not practical to apply because the cellular M2M network is more vulnerable to various attacks. In this work, we consider security aspects for cellular M2M communication and propose a key management. Our proposal can provide reliability and efficiency for secure cellular M2M communication network.
