Software-defined networking (SDN) supports flexibly routing and switching by splitting the control plane and data plane in network devices. However, the security resource utilization now in SDN is inefficient, especially in the process of routing path construction. In this paper, we present a novel model for SDN controller to construct secure routing paths based on Network Security Virtualization...
In Ubiquitous Healthcare System (U-Healthcare), authentication is an essential task for secure medical information transmissions. In a recent paper, Kim proposed a smartcardbased authentication scheme for privacy preservation in UHealthcare. This scheme can protect user context privacy and is believed to have many abilities to resist a range of attacks, even though the secret data stored on the smartcard...
Software Defined Networking (SDN) is one of the typical flow-rule-driven networks. In SDN, a centralized controller dictates the network behavior and configures network devices with many flow rules, and the validity and consistency of flow rules could guarantee the normal operations in SDN. Therefore, SDN requires a secure and efficient mechanism to manage and authenticate flow rules between the application...
