A Novel Hybrid Cellular Automata Based Cipher System for Internet of Things

High volume products for Internet of Things have a constricted cost that limit the cryptographic implementation in such devices. Thus, there is a need to design a lightweight cryptography stream cipher that can fit such low computation devices with low cost. This paper proposes a lightweight stream cipher that can enhance Linear Feedback Shift Register (LFSR), Feed Carry Shift Register (FCSR) within the Shrinking Generator stream cipher and used Cellular Automata (CA) to update the cipher stream.

Securing E-Seal real time tracking system for Internet of Things

High volume products such as RFID tags and Wireless Sensors (WS) have a constricted cost that limit the cryptographic implementation in such devices. Our work focuses on securing an E-Seal that can be used to secure the communication of the real time tracking communication by using a symmetric cryptosystem. Also, this paper addresses the use of the asymmetric cipher which is an Identity Based Cryptosystem (IBC) based with lightweight computation specification that can be used in low computation devices for locking and unlocking of the E-Seal.

Enhancing the Security of the Shrinking Generator Based Lightweight Mutual Authentication RFID Protocol

Radio Frequency Identification (RFID) is a low computation power devices used to identify objects or subjects. Thus the low power devices suffer from major security issues, especially in the areas of privacy and authentication. Therefore, researchers tried to suggest lightweight cryptography protocols. This paper suggests an improvement for the lightweight mutual authentication proposed protocol using Shrinking Generator (SG) by Shemaili et al. since the protocol is vulnerable to a serious attack that can expose the tag data and compromise it. Also, the paper presents a scenario about securing the airport environment using the SG-Based protocol.

ID-based secure real-time tracking system

This article focuses on the security issues involved in the transportation of valuable materials. It tries to build a secure smart real-time freight tracking system in which the valuable materials can be under inspection and control at all times during its transportation from the supplier to the end user. The real-time tracking system can be achieved by combining technologies from Real-Time Tracking Systems (RTTSs), such as GPS and RFID, while the system environment sensing can be achieved using Wireless Sensor Network (WSN) that can add sensing ability to the moving valuable materials. This paper not only proposes a novel Identity-Based Cryptosystem (IBC) for securing an E-Seal that can be used to secure the communication of the real-time tracking communication but also addresses IBC based with lightweight computation specification that can be used in low computation devices for locking and unlocking of the E-Seal.

IoT Implementation of SGCA Stream Cipher Algorithm on 8-Bits AVR Microcontroller

Recently, the computing environment is changing due to the advent of resource-constrained devices, such as smart cards. That causes a limitation in providing some main feature to the low constraint computation devices such as security. The main purpose of this paper is to design a lightweight and secure stream ciphers for IoT to secure hardware and software that can fit constrain resources devices. Thus, we implement our proposed solution on 8 bits AVR microcontroller in order to study the required memory and speed. Also, two hardware algorithms which are Trivium and Grain are implemented and comparison provided between them and the proposed stream ciphers requirements. Also, our proposed SGCA algorithm proves to have less memory and time consuming than Trivium and Grain algorithms.

A New Lightweight Mutual Authentication Protocol to Secure Real Time Tracking of Radioactive Sources

Radioactive applications are employed in many aspects of our life, such as industry, medicine and agriculture. One of the most important issues that need to be addressed is the security of the movement of radioactive sources. There are many threats that may occur during the transportation of the radioactive sources from one place to another. This paper investigates the security issues in the transportation of the radioactive sources. Thus, it is an attempt to build a secure, real time freight tracking system in which the radioactive source can be under inspection and control at all times during transportation from the shipment provider to the end user. Thus, we proposed a novel lightweight mutual authentication protocol to be used for securing the transportation of radioactive materials. Also, the security requirements for the proposed protocol were verified using the Scyther tool.

Characteristics and properties of United Arab Emirates fog events using meteosat second generation thermal and visible channels

Satellite remote sensing is an important tool in the detection and short range forecasting (now-casting) of fog events. Fog over land develops primarily during the late-night and pre-dawn hours, infrared remote sensing is indispensable in observing fog formation, while visible imagery helps to monitor the extent and density of fog after sunrise. On average there are more than forty five fog occurrences in UAE per year. This paper describes the methods used by EIAST for using satellite remote sensing for detecting and now-casting fog events. The temperature difference between two infrared bands (11 μm and 4 μm) forms the basis for fog detection and classification [1].

Combing MSG thermal channels with meteorological data for fog forecasting and mapping over desert areas in the UAE

Satellite remote sensing is an important tool in the detection and short range forecasting (nowcasting) of fog events. Fog over land develops primarily during the late-night and pre-dawn hours, infrared remote sensing is indispensable in observing fog formation at night, while visible imagery helps to monitor the extent and density of fog after sunrise. Satellite remote sensing is widely used in the United States and Europe in detecting and nowcasting fog events. The temperature difference between two infrared bands (11 µm and 4 µm), available in geostationary satellites, forms the basis for fog detection and classification [1]. In this study an algorithm for now-casting, detecting and monitoring fog events in the United Arab Emirates was developed. The major approach is based on developing a neural-networks system in MATLAB, mainly using METEOSAT SEVIRI data and local meteorological data. The final developed tool is named UAE-FAD (Fog Automatic Detector) and will provide real-time information for further research and development as well as for public and civil services.
