Framework of trusted wireless sensor node platform for Wireless Sensor Network / Yusnani Mohd Yussoff

Wireless Sensor Networks (WSNs) have shown great promise as the emerging technology for data gathering from unattended or hostile environment. The advancement in micro-electro-mechanical sensor technology, wireless communication technology and the recent scavenging energy have gradually expanding the acceptance of WSN related applications. The design of sensors that are small, low cost, low power and combined with its unattended nature has made it more viable and indirectly promotes its popularity for future solutions in various real-life challenges. One of the most challenging yet important security issues in Wireless Sensor Network is in establishing trusted and secured communication between sensor node and base station. While the term trusted has been widely used referring to valid nodes in the group, this thesis refer the term trusted based on Trusted Computing Group (TCG) specifications. With limitations in the present solutions such as late discovery of invalid nodes such in Trust Management System and high energy consumption with external security chip due to the used of Trusted Platform Module chip; a Framework of a Trusted Wireless Sensor Node is presented

Low power multicarrier- code division multiple access receiver on field programmable gate array

This paper presents a low power multi-carrier code division multiple access (MC-CDMA) receiver on field-programable gate array (FPGA). Most of the wireless application nowadays such as wireless sensor networks, portable computation and many more require a low power design. Time-division multiple access (TDMA) is used in most wireless receivers are not very efficient since they adopt scheduling technique. The first objective of this paper is to design and verify a low power MC-CDMA receiver and the second objective is to implement the MC-CDMA receiver on FPGA. MC-CDMA act as a processor with the ability to process transmit or receive data simultaneously over a single communication channel. The MC-CDMA design in this paper consists of pipelined FFT and combiner. The primary purpose of pipelined FFT plus combiner module in this research is to execute the instruction on communication (data send and receive) and self-organization. Besides these two modules, there is a memory for temporarily storing the data and an internal clock, among other things. To accomplish these, the designs have been carried out using Verilog coding in Modelsim software, and the design verifications are done through Matlab. The design implementation is via Quartus and on DE2-115 Altera FPGA board. The functionality analyses have been carried out on simulation, and the hardware implementation of the MC-CDMA receiver is tested. Both simulation and hardware execution are successful where the receiver received and displayed the output accordingly. MC-CDMA achieves 39.13mW total power consumption

A Review of Physical Attacks and Trusted Platforms in Wireless Sensor Networks

AbstractWireless Sensor Networks (WSNs) have shown great promise as the emerging technology for data gathering from unattended or hostile environment. The advancement in micro-electro-mechanical sensor technology, wireless communication technology and the recent energy scavenging have greatly contributed to the widespread acceptance of WSN related applications. In addtiion, the design of sensors that are small, low cost, low power and combined with its ability to be left unattended has made it more viable and indirectly promotes its popularity for future solutions in various real-life challenges. However, in sensor network, the nodes are physically accessible by adversaries and have been known to expose cryptographic materials such as the encryption keys and other important data in the sensor nodes. Acknowledging the severity of such attacks, this paper first presents the review on physical attacks followed by the introduction of trusted platform with protected memory that not only protect sensor node's sensitive credentials but also provide a concrete way to trust nodes in the dedicated wireless sensor network. Finally, summarization of proposed IBE_Trust framework is presented and briefly discusse

Hybrid Cryptographic Approach for Internet Ofhybrid Cryptographic Approach for Internet Of things Applications: A Review

Cryptography is described as the study of encrypting or secret Cryptography is described as the study of encrypting or secret writing of data using logical and mathematical principles to protect information. This technique has grown in importance in computing technologies for banking services, medical systems, transportation and other Internet of Things (IoT)-based applications which have been subjected to increasing security concerns. In cryptography, each scheme is built with its own respective strength, but the implementation of single cryptographic scheme into the system has some disadvantages. For instance, symmetric encryption method provides a cost effective technique of securing data without compromising security. However, sharing the secret key is a vital problem. On the other hand the asymmetric scheme solves the secret key distribution issue; yet the standalone technique is slow and consumes more computer resources compared to the symmetric encryption. In contrast, hashing function generates a unique and fixed-length signature for a message to provide data integrity but the method is only a one-way function which is infeasible to invert. As an alternative to solve the security weakness of every single scheme, integration of several cryptographic of every single scheme, integration of several cryptographic schemes which are also called the hybridization technique is being proposed offering the efficiency of securing data and solving the issue of key distribution. Herein, a review study of articles related to hybrid cryptographic approach from 2013to 2018 is presented. Current IoT domains that implemented hybrid approaches were identified and the review was conducted according to the category of the domain. The significant findings from this literature review included the exploration of various IoT domains that implemented hybrid cryptographic techniques for improving performance in related works. From the findings, it can be concluded that the hybrid cryptographic approach has been implemented in many IoT cloud computing services. In addition, AES and ECC have been found to be the most popular methods used in the hybrid approach due to its computing speed and security resistance among other schemes
