Secured Network on Chip (NoC) Architecture and Routing with Modified TACIT Cryptographic Technique

AbstractNetwork on Chip (NoC) architecture needed secured data processing and routing in multicore system on Chip (SoC). Sometime it becomes very difficult to provide secured network routing for physically access network. The performance of NoC architecture depends on switching techniques, routing scheme and topological structure. The paper proposed the chip implementation of the new technique of securing data in NoC routers. Many algorithms have been anticipated already for secured NoC routing but limited to their key size and block size. In the paper, NoC architecture is integrated with modified TACIT security algorithm on Virtex-5 FPGA. The key generation scheme is considered based on Hash function and distributed under 4 Hash function (4H) scheme. The greatest advantage of TACIT security algorithm is that the block size and key size both can be of ‘n’ bit. The design is developed for ‘n’ bit with the help of VHDL programming language in Xilinx ISE 14.2 and Modelsim 10.1 b software and synthesized for 512 and 1024 bit of block size on Virtex-5 FPGA. The design is optimized with the help of device utilization summary, timing parameters, maximum frequency and memory support

Energy Efficient RF Remote Control for Dimming the Household Applainces

During recent years there is a strong trend towards radio frequency (RF) remote controls as it is delivering even more comfort to the users and increased usability with high robustness of the RF links. Lower power consumption with new features and security make RF remote control systems more competitive with widely used IR remote control systems.  In this paper we propose, a RF module based real time system, which is an integrated system designed to control the dimming or speed of the appliances. Zigbee module is used as RF module to establish wireless link between Remote and appliance section having 9600kbs baud rate and range of 100m. Dimming control circuits is part of appliances section which is used to control the appliances corresponding to signals generated by the remote section. This system provides energy efficient solution for household uses. DOI: http://dx.doi.org/10.11591/telkomnika.v13i2.7046

The chip design is verified for the 10-bit seeding sequence of LFSRs to result in 1023-bit code with the frequency support of 310 MHz, and 9.285 ns delay. • The chip design is simulated based on seed data and different tap points of LFSR registers from which the bits are considered to generate the feedback. The design is scalable and has greater potential to extend to a larger extent. The behavior of the gold code depends on the maximum length sequence, absolute cross-correlation, and size of LFSR

STRUCTURAL, THERMAL AND CONDUCTIVITY STUDIES OF PAN-LIBF4 POLYMER ELECTROLYTES

The polymer electrolytes with various compositions of Polyacrylonitrile/N-N Dimethylformamide (DMF)/Lithiumtetrafluoroborate (LiBF4) are synthesized by solution casting technique. The free standing, clear and transparent 60-80 micron thick films are formed. The promising structural and complexation changes in polymer electrolytes have been explored by X-ray diffraction (XRD) and Fourier transform infra-red (FTIR) techniques. The thermal properties of all solid polymer electrolytes (SPE) were studied by Thermo gravimetric Analyzer (TGA) and Differential Thermal Analyzer (DTA). The electrical properties, i.e., ionic conductivity of solid polymer electrolytes has been measured as a function of temperature and composition. A Polymer membrane for 3 wt. % of salt has a conductivity of 3.06x10-4 mScm-1 at room temperature and 1.53x10-3 mScm-1 at 358K. The conductivity values increased with increase in temperature and offered an ionic conductivity of the order of 10-3 mScm-1 at temperatures 358K. Activation energy, enthalpy and entropy values are determined for all polymer complexes

WPAN and IoT Enabled Automation to Authenticate Ignition of Vehicle in Perspective of Smart Cities

Currently, two-wheelers are the most popular mode of transportation, driven by the majority the people. Research by the World Health Organization (WHO) identifies that most two-wheeler deaths are caused due to not wearing a helmet. However, the advancement in sensors and wireless communication technology empowers one to monitor physical things such as helmets through wireless technology. Motivated by these aspects, this article proposes a wireless personal network and an Internet of Things assisted system for automating the ignition of two-wheelers with authorization and authentication through the helmet. The authentication and authorization are realized with the assistance of a helmet node and a two-wheeler node based on 2.4 GHz RF communication. The helmet node is embedded with three flex sensors utilized to experiment with different age groups and under different temperature conditions. The statistical data collected during the experiment are utilized to identify the appropriate threshold value through a t-test hypothesis for igniting the two-wheelers. The threshold value obtained after the t-test is logged in the helmet node for initiating the communication with the two-wheeler node. The pairing of the helmet node along with the RFID key is achieved through 2.4 GHZ RF communication. During real-time implementation, the helmet node updates the status to the server and LABVIEW data logger, after wearing the helmet. Along with the customization of hardware, a LABVIEW data logger is designed to visualize the data on the server side

An Insight to the Outage Performance of Multi-Hop Mixed RF/FSO/UWOC System

In this paper, we investigate the outage performance of the three-hop mixed system integrating radio frequency (RF), free space optics (FSO), and under water optical communication (UWOC) system. The closed-form analytical expressions for the outage probability of the system are derived. In the considered system, the RF channel follows the Nakagami-m distribution, the FSO channel observes the Gamma-Gamma fading statistics, and the UWOC link experiences a mixture Exponential Generalized Gamma (EGG) fading distribution. To verify the derived analytical expressions, numerical simulations are also carried out, and we present the influence of the various link parameters such as path loss, atmospheric turbulence, pointing errors, angle-of-arrival fluctuations, water salinity, and scintillation on the performance of the decode and forward (DF) relayed multi-hop communication system
