Improving Security Using Modified S-Box for AES Cryptographic Primitives

The growing network traffic rate in wireless communication demands extended network capacity. Current crypto core methodologies are already reaching the maximum achievable network capacity limits. The combination of AES with other crypto cores and inventing new optimization models have emerged. In this paper, some of the prominent issues related to the existing AES core system, namely, lack of data rate, design complexity, reliability, and discriminative properties. In addition to that, this work also proposes a biometric key generation for AES core that constitutes simpler arithmetic such as substitution, modulo operation, and cyclic shifting for diffusion and confusion metrics which explore cipher transformation level. It is proved that in AES as compared to all other functions S-Box component directly influences the overall system performance both in terms of power consumption overhead, security measures, and path delay, etc.

Implementasi Manajemen Bandwidth dengan Metode Hierarchical Token Bucket (HTB) dan Per Connection Queue (PCQ) pada STMIK Antar Bangsa

Intisari—Penggunaan internet saat ini sangat dibutuhkan untuk kelancaran dan kemudahan sebuah pekerjaaan diperusahaan yang umumnya menggunakan internet secara bersamaan. Semakain bertambahnya pengguna internet semakin berkurangnya performa kemampuan internet. Cara yang dapat ditempuh untuk mengurangi penurunan performansi jaringan yaitu dengan melakukan manajemen Bandwidth. Manajemen Bandwidth sangat penting dalam pengaturan alokasi Bandwidth yang akan diberikan kepada user untuk menghindari perebutan alokasi Bandwidth yang ada di jaringan. Pada penelitian ini manajemen Bandwidth menggunakan dua metode, yaitu Per Connection Queue (PCQ) dan Hierarchical Token Bucket (HTB). PCQ pada queue type adalah salah satu fitur dari MikroTik untuk membantu memanage traffic rate dan traffic packet sedangkan Hiearachical Token Bucket (HTB) merupakan jenis aplikasi yang digunakan untuk membatasi akses menuju ke port/IP tertentu tanpa mengganggu trafik Bandwidth pengguna lain. Hasil yang didapatkan bahwa kualitas jaringan dengan menggunakan metode antrian HTB (Hierarchical Token Bucket) dan metode PCQ (Peer Connection Queue) lebih optimal, hal ini dikarenakan semua client akan mendapatkan kuota Bandwidth sesuai dengan rule yang diterapkan pada Bandwidth manajemen.

High-speed network traffic capturing and processing tools

Network stacks currently implemented in operating systems can no longer cope with the packet rates offered by 10 Gbit Ethernet. Thus, frameworks were developed claiming to offer a faster alternative for this demand. These frameworks enable arbitrary packet processing systems to be built from commodity hardware handling a traffic rate of several 10 Gbit interfaces, entering a domain previously only available to custom-built hardware. In this paper, we survey various frameworks for high-performance packet IO and their interaction with a modular frameworks and specialized virtual network functions software for high-speed packet processing. We introduce a model to estimate and assess the performance of these packet processing frameworks. Moreover, we analyze the performance of the most prominent frameworks based on representative measurements in packet capturing scenarios. Therefore, we provide a comparison between them and select the area of applicability.

Rekayasa Lalu Lintas Pada Kawasan Simpang Jl. Lingkar Tengah – Jl. DR. Leimena Di Kota Makassar

Transportation problem, either in general or specifically in traffic, is a phenomenon occuring in human life. As the population of city increased, so does the traffic rate. If this is not followed by adequate improvement of transportation infrastructure, an imbalance might occur which will result in traffic jam. It can be seen particularly at Lingkar Tengah – Dr. Leimena road junction connecting Jalan Perintis Kemerdekaan - Dr Leimena road due to driver/rider against the direction. Data analysis and planning using method of road capacity manual (MKJI 1997) and the traffic modelling using PTV Vissim. Based on road performance analysis it is known that DS (degree of saturation) is 0.12 with service level ‗A‘ and average speed ≥23km/h with service level ‗D‘. From the calculation result, modelling is conducted using PTV Vissim modelling. Alternative for handling the intersection is using 2 methods, which are traffic light signaling for 3 phases with immediate straight at west corner and immediate left turning at east corner and bridge closure on Dr. Leimena road. Using PTV Vissim, the result is that intensity of travel time increases about 47.68% and 57.40% on the intersection.

Community Structure of Road Associated Avifauna along theUrban Gradient in Mintal, Davao City, Southern Philippines

The community structure of avifauna along the urbanization gradient in Mintal, Davao Citywas surveyed and analyzed. A total of 4,210 individuals from 34 species belonging to 23 fam-ilies were recorded. Seven species are Philippine endemics and five are introduced species.Correlation and regression analysis showed a positive relationship between increasing vegeta-tion cover with species richness and a negative relationship with abundance. Oppositely, in-creasing urbanization (increase built-up cover, pedestrian and traffic rate) were observed tohave positive relationship to abundance but negative relationship to species richness. Thus, the avian community in the urbanization gradient of Mintal, Davao City follows the general ac-cepted trend that in heavily disturbed areas, species richness is at its lowest while total birdabundance is at its peak. This study also suggests the importance of green spaces with lessertraffic rate in urban landscapes that could support higher avian diversity which includes Philip-pine endemic species.

Analysis of hybrid approach for Answering holistic queries in Wireless Sensor

Sensor networks are greatly utilized in unique areas like the transportation methods, wellbeing monitoring, soil monitoring, habitat monitoring and so forth. Clients pose queries to sensors and acquire sensing information. In view of the low quality detecting devices, sensor information is regularly boisterous. Continuous queries are more commonly employed to increase the reliability of query result. On this work we revolve round on regular holistic queries like Median. Present methodologies are for essentially the most phase supposed for non-holistic queries like Average. As a result of the no decomposable property of sensors, answering holistic queries are given much less value. We initially recommend two ways elegant on the information correlation be tween’s two rounds, with one for finding the detailed solutions and the other one for opting for the estimated outcome. We at that factor consolidate the two proposed plans into a hybrid methodology, which is flexible to the information evolving velocity. The effects show that our methodology has reduced the traffic rate even as keeping equal accuracy.

Designing Software Define Network Prototypes with Open vSwitch as Monitoring Traffic Police on The Raspberry Pi

Technology is growing from year to year even day to day, this has made the increasing need for infrastructure that supports especially in aspects of computer networks. The increasing number of traffic that is burdening the router or switch encourages the increasing number of nodes to network devices with the aim of reducing and dividing the burden on network traffic. The need for traffic management and control is very important because with the increasing number of network devices and the higher traffic, making a network administrator need more time to handle if there are problems in the network. This research is trying to implement open vSwitch technology on low-cost raspberry pi devices. And by applying the traffic shaping and traffic rate methods by utilizing the traffic control feature on Linux, and then try to divide the amount of traffic received by network devices so that the traffic load becomes controlled. The results of this study, show the results of successful implementation and traffic management work well.

A Novel Traffic Rate Measurement Algorithm for Quality of Experience-Aware Video Admission Control

With the inevitable dominance of video traffic on the Internet, providing perceptually good video quality is becoming a challenging task. This is partly due to the bursty nature of video traffic, changing network conditions and limitations of network transport protocols. This growth of video traffic has made Quality of Experience (QoE) of the end user the focus of the research community. In contrast, Internet service providers are concerned about maximizing revenue by accepting as many sessions as possible, as long as customers remain satisfied. However, there is still no entirely satisfactory admission algorithm for flows with variable rate. The trade-off between the number of sessions and perceived QoE can be optimized by exploiting the bursty nature of video traffic. This paper proposes a novel algorithm to determine the upper limit of the aggregate video rate that can exceed the available bandwidth without degrading the QoE of accepted video sessions. A parameter $\beta$ that defines the exceedable limit is defined. The proposed algorithm results in accepting more sessions without compromising the QoE of on-going video sessions. Thus it contributes to the optimization of the QoE-Session trade-off in support of the expected growth of video traffic on the Internet.
