A lightweight multi-layer authentication protocol for wireless body area networks
Future Generation Computer Systems, 2018Co-Authors: Jian Shen, Jun Shen, Shaohua Chang, Qi Liu, Xingming SunAbstract:Nowadays, the technology of Internet of Things (IoT) is getting more and more important which brings a lot of convenience to people's life and city's development. As a Key Application of IoT, wireless body area networks (WBANs) provides people high quality of life and high level of medical service. However, due to the sensitiveness of medical system, security and privacy issues in WBANs are very important. In previous research, there are no comprehensive authentication protocols designed for WBANs according to its characteristics of network structure. In this paper, we propose an efficient multilayer authentication protocol and a secure session Key generation method for WBANs. Firstly, we design a one-to-many group authentication protocol and a group Key establishment algorithm between personal digital assistance (PDA) and each of sensor nodes with energy efficiency and low computational cost. Then, we present a new certificateless authentication protocol with no pairings based on certificateless cryptography between PDA and Application provider (AP), using ECC algorithm that provides low computational cost with high security. In addition, the validation of the proposed protocol can be proved. Finally, the security and performance analysis shows that our protocol is secure and efficient.

mixed tunnel fet mosfet level shifters a new proposal to extend the tunnel fet Application domain
IEEE Transactions on Electron Devices, 2015Co-Authors: Marco Lanuzza, Sebastiano Strangio, F Crupi, P Palestri, D EsseniAbstract:In this paper, we identify the level shifter (LS) for voltage up-conversion from the ultralow-voltage regime as a Key Application domain of tunnel FETs (TFETs). We propose a mixed TFET–MOSFET LS design methodology, which exploits the complementary characteristics of TFET and MOSFET devices. Simulation results show that the hybrid LS exhibits superior dynamic performance at the same static power consumption compared with the conventional MOSFET and pure TFET solutions. The advantage of the mixed design with respect to the conventional MOSFET approach is emphasized when lower voltage signals have to be up-converted, reaching an improvement of the energy-delay product up to three decades. When compared with the full MOSFET design, the mixed TFET–MOSFET solution appears to be less sensitive toward threshold voltage variations in terms of dynamic figures of merit, at the expense of higher leakage variability. Similar results are obtained for four different LS topologies, thus indicating that the hybrid TFET–MOSFET approach offers intrinsic advantages in the design of LS for voltage up-conversion from the ultralow-voltage regime compared with the conventional MOSFET and pure TFET solutions.
