Title:	SECURE DYNAMIC SYSTEM DEVELOPMENT METHOD (SDSDM): A SURVEY ABOUT ITS SUITABILITY
Author:	IMRAN GHANI, ABDULLAHISANI, NAGHMEH NIKNEJAD, MANNIR BELLO, SHAHID KAMAL, MUHAMMAD WASEEM CHUGHTAI, SEUNG RYUL JEONG
Abstract:	Building secure software is about taking security into account during all phases of software development. However, the major problem in agile methods is the lack of basic security elements in their phases and practices. One of such method is Dynamic System Development Method (DSDM).Based on this study, we have observed that the original/traditional DSDM does not help guide the agile to develop secure software. In order to address this issue, we introduced additional phases and sub-phases to the original/traditional DSDM to integrate security. The proposed model is named Secure Dynamic System Development Method (SDSDM), which has six phases. These phases and sub-phases are feasibility study, functional model iteration, secure functional model iteration, secure design, design and build iteration and implementation. Our findings highlight an improved agility in DSDM after integration of security. However, the study focuses on a questionnaire (survey) where the subject matter experts’ opinion has been used to validate our model. Based on the experts’ opinion, we can say that it is possible to develop secure software using SDSDM model without affecting its agility negatively.

Title:	A NOVEL VLSI BASED CRYPTOCODING TECHNIQUE USING ERROR CONTROL ALGORITHM
Author:	B. SENTHILKUMAR, V. RAJAMANI
Abstract:	This paper presents a hardware implementation for Encoder and Decoder of the cryptography technique using versatile Error Control Algorithms of Block Codes used in wireless communication networks. This work is focused on the designing of VLSI based hardware implementable and more secured alternative of existing software based symmetric cryptography techniques using DES (Data Encryption Standard) and AES (Advanced Encryption Standard Algorithm). In this design process, traditional methods of sub key generation using bit shifting along with modulo 2 addition, performance of padding and puncturing the bits of words are done so as to maintain the reliability of the design at par with conventional technique. In this design, (7,4) Block code with hamming code algorithm is considered as it has very low probability to retrieve originality without specific syndrome analysis and can be easily penetrated between any number of bits of original message as required by the Cryptography. This design is simulated and the synthesis report is generated using Verilog coding of Xilinx ISE software and the modules and results are illustrated. The report and result reveals that the proposed design will occupy very lesser number of components with reliable performance. This will lead to the small amount of power consumption and compactness in hardware implementation. Also, it is observed that the even though the used key size is small, the complexity for the intruder to retrieve the original message is greatly increased by incorporating the variety of hardware diversifying practice without sacrificing the strength of required cryptography technique. The test result shows the significance of the proposed design as the same set of message never produces the same set of cipher text. So that the computational attacks using software based iteration can not be used to track the plain text.

Title:	INITIAL TRUST IN INTERNET BANKING SERVICE IN JORDAN: MODELING AND INSTRUMENT VALIDATION
Author:	ALI ALJAAFREH, AHMED AL-ANI, RAID ALADAILEH, RASHA ALJAAFREH
Abstract:	As with many other e-services, the adoption rate of Internet banking services (IBS) in developing countries is relatively low compared to developed countries. It is well-established that customer’s trust plays an important role in adopting new technologies, and hence, initial trust could be the first issue that needs to be investigated when studying the adoption of online banking. The aim of this study is to develop and validate a research instrument empirically, and then use it to examine a proposed conceptual model of initial trust for IBS in developing countries. The model’s constructs are integrated from the trust literature, diffusion of innovation theory (DoI), and the Hofstede’s culture theory. This paper also aims to develop and validate a research instrument to examine the research model. We conducted a pilot study in Jordan, one of the developing countries in the Middle East. A survey was carried out, and a total of 75 responses were gathered in the study. The collected data was analyzed using IBM SPSS 22.0. Results of the pilot study are used to validate the instrument and to refine the proposed model. The validated and refined instrument will be used to examine the model in the intended primary study.

Title:	PERFORMANCE OF TWO-PATH SUCCESSIVE RELAYING IN THE PRESENCE OF INTER-RELAY INTERFERENCE
Author:	QIAN YU LIAU, CHEE YEN LEOW
Abstract:	Half-duplex constraint refers to the inability of a radio to transmit and receive signals simultaneously due to the hardware limitation. In cooperative communication, half duplex constraint requires orthogonal time or frequency channel use between source transmission phase and relay transmission phase. This limits the spectral efficiency of conventional relaying to half of the performance of direct transmission without relay. Two-path successive relaying has been proposed to relax this half-duplex constraint by allowing non-orthogonal transmission, where the source transmits new message continuously in every time slot. In two-path successive relaying, two relays are scheduled to assist the transmission alternately. However, the inter-relay interference degrades the performance significantly since the two relays are not operating in orthogonal channel. Majority of the existing literature neglects the inter-relay interference and over estimates the performance of two-path successive relaying. The main objective of this paper is to investigate the actual interference limited performance of two-path successive relaying compared to conventional half-duplex relaying in terms of ergodic capacity. We consider several channel and system conditions to identify the optimal scheme in respective conditions. The results show that the two-path successive relaying is not always optimal if compared to the conventional half-duplex relaying in interference limited scenario.

Title:	MALICIOUS NODE DETECTION THROUGH TRUST AWARE ROUTING IN WIRELESS SENSOR NETWORKS
Author:	RAJA WASEEM ANWAR, MAJID BAKHTIARI, ANAZIDA ZAINAL, KASHIF NASEER QURESHI
Abstract:	Wireless sensor network are constituted by a large number of tiny size sensors and distributed randomly for gathering information. These types of networks have remarkable applications and demand worldwide. The wireless sensor network has been suffered with variety of attacks because of its design and deployment nature. The previous traditional approaches including cryptography, authentication cannot work properly against node misbehavior attacks. To solve this problem, we propose a Trust Aware Wireless Routing Protocol (TAWRP) for detection and isolation of malicious nodes in network. The main aim of TAWRP is to establish an optimal route with trusted nodes and effectively forward the packets from source to destination with minimum packet loss. The performance of TAWRP is evaluated in terms of packet delivery ratio and routing overhead. The results clearly showed that TAWRP can achieve high delivery ratio and efficient in routing overhead in the presence of malicious nodes.

Title:	RECENT METHODS AND TECHNIQUES IN VIDEO WATERMARKING AND THEIR APPLICABILITY TO THE NEXT GENERATION VIDEO CODEC
Author:	M.F.L. ABDULLAH, ALI A. ELROWAYATI, AZIZAH ABD MANAF, ZAKARIA S. ZUBI
Abstract:	High efficiency video coding (HEVC) is the newest video coding generation of the ITU-T and ISO/IEC, which first appeared in January 2013. It has the advantage of reducing the bit rate by as much as 50 % when compared to H.264 while maintaining the same visual quality. In the last decade, authentication and copyright protection methodologies have become one of the essential items in order to protect video contents by embedding within an efficient video codec. Thus, the objective of this paper is to revise recent developments in the area of watermarking techniques for video coding schemes and their applicability to the new Standard HEVC. The results of this study provide motivation to achieve a higher embedding capacity and higher compression performance for HEVC compared to H.264/AVC especially, for low bit-rate coding.

Abstract:	Object class recognition has exhibited significant progress in recent years and is now an integral component of many machine vision applications. However, object class recognition using visual attention image segmentation is a novel idea, which has only been developed in the past decade. This paper presents a comprehensive survey on object class recognition and object recognition algorithms, in addition to their applications based on visual attention region selection methods that as recently published. Additionally, increased efforts have been directed to the development of a generic method for categorizing all objects in a domain including examples such as Winn’s Method, used to recognize object classes at a glance. The Majority of object class recognition algorithms are highly dependent on shape matching results. The purpose of this review is to provide a comparison among the visual attention (bottom-up and top-down), object recognition (e.g., SIFT, SURF and PCA-SIFT) and object class recognition methods, aimed to researchers identifying the most appropriate method for a particular purpose. This survey is suitable for researchers in the pattern recognition field, providing familiarity with the existing algorithms for object classification from image acquisition steps to final output (i.e., image segmentation, object recognition and object classification). At the end of each part, the challenges, critical analysis table are provided and future directions of every method are suggested for developing new ideas end of this paper. Additionally, this approach allows researchers to find the definition of keywords and to obtain brief knowledge concerning how each method works and what obtained results are for various datasets.

Title:	HUNTING SEARCH ALGORITHM TO SOLVE THE TRAVELING SALESMAN PROBLEM
Author:	AMINE AGHARGHOR, MOHAMMED ESSAID RIFFI
Abstract:	Traveling salesman problem is a classic combinatorial optimization problem NP-hard. It is often used to evaluate the performance of new optimization methods. We propose in the present article to evaluate the performance of the new Hunting Search method to find better results for the traveling salesman problem. Hunting Search is a meta-heuristic inspired by the method of group hunting of predatory animals. It is part of the evolutionary algorithms used to solve the continuation optimization problems. The work presents an adaptation of this method in a discrete case by redefining operations of the method into operations of permutation in the path of the visited cities of the traveling salesman. The proposed method was tested on the instances of reference of TSPLib Library and it gave good results compared to the recent optimization methods.

Title:	SOFT SWITCHING MODEL OF INTERLEAVED BUCK CONVERTER
Author:	R. PREMALATHA, Dr. P. MURUGESAN
Abstract:	This paper presents the modeling and simulation of interleaved buck converter (IBC) with open and closed loop operation having low switching losses of ripple with 0.012 and improved step-down conversion ratio, which is suitable for the application where the input voltage is high. As Cuk, Sepic and Zeta converters the two active switches are connected in series and a coupling capacitor is employed in the power path. The proposed IBC shows the voltage stress across all active switches is half of the input voltage before turn on or after turnoff. The capacitive discharging and switching losses can be reduced considerably to have higher efficiency, higher step-down conversion ratio, higher switching frequency and a smaller output ripple compared with a conventional IBC. The model of Interleaved buck converter system are presented.

Title:	IMAGE RECOGNITION BASED ON SIMILARITY OF CURVE CHARACTERISTICS INVARIANT TO TRANSLATION
Author:	DINA INDARTI, SARIFUDDIN MADENDA, TUBAGUS MAULANA KUSUMA, DEWI AGUSHINTA R
Abstract:	Objects similarity are required in image recognition, such as in quality control problems. Characteristics of objects in an image are represented by the characteristics of the detected edges. Curve is one of the detected edge beside point, line, and region. Curve provides geometric and structural information of the image. It gives better information than point. The existing research related to the similarity of curve characteristic are still facing problems associated with invariant to geometric transformations. Therefore, this research discusses how to use the characteristics of curve, so that the curve similarity can be invariant to translation. In using the characteristics of curve, the first step is curves tracking using 8 (eight) directions chain codes. Furthermore, the algorithms to determine the type of curve and to determine the similarity between curves which invariant to translation are explained. The definition of curve itself was used in determining the types of curves. The similarity of curves is determined based on the characteristics of curves. This proposed image recognition algorithm can detect similar image while geometric translation is occurred.
