Abstract

To connect the office with another office in different location, it takes the transmission media for data communication. one of the transmission media that can be used is Open VPN using the internet. OSPF routing required to connect all routers in the network using a VPN.OSPF routing on the Open VPN network, could be a solution for companies who want to build a network to connect multiple offices in different locations with a network.The implementation of OSPF routing in the Open VPN network uses three pieces of routerboard with one public IP. The testing is done by analyzing the process of selection of routing line, analysis of time speed of convergence, analysis of speed is the literature study, simulation to the virtualbox, and implementation to test-bed network.The test results convergence time using the same ISP is55,28 seconds and using a different ISP is 55,seconds. Test results on the routing update process with the same ISP is 7,23 and 9,63 seconds using a different ISP. Overall the OSPF routing on the Open VPN networks able to work well with convergence time and time routing updates fast and up to date

Abstract

Department of Transportation, Communication and Information of Manggarai Regency, is one of the instance of Regional Government of Manggarai, NTT, which is responsible to help the Head of Region concerning transportation, communication and information affairs. The lackness of human resources which was competent in computer networking, the high cost of VSAT IP Broadband internet service and maintenance cost of network’s backbone which is wireless based, have been becoming a problem to the Department concerning their main duties. As an impact, it is necessary to the Department to change their network’s backbone to wired network based, using VLAN. VLAN can divide network into several segments with low cost implementation. The using of VLAN Trunking Protocol (VTP) will ease the network administrator in managing VLAN. The VLAN design in this study used hierarchical model. The logical layer for data distributing was divided into two layers, core/distribution and access layer. Routing between VLANs used “router-on-a-stick using trunk” model, so that the workstations which were owned by different VLAN can communicate each other by using one router only. By using simulation method for testing the design, it was discovered that all workstations between different VLAN have been successfully connected each other and all servers were well-functioned.

Abstract

The average temperature of global warming on the earth's surface today has increased by 0.74 ± 0:18°C, the increase was due to the increase in the average temperature of the atmosphere, ocean and land earth. Emissions of the most influential on the quality of the air is carbon emissions, especially carbon dioxide (CO2). The CO2 contributes to global warming is 50%. The CO2 gases absorb and reflect radiation emitted waves of the earth, so that the heat will be stored on the surface of the earth. This study aimed to design a data logger system monitoring the level of concentration of CO2 using the oxygen sensor (OOM202), carbon dioxide sensor (MG81), as well as temperature and humidity sensors (DHT22) with microcontroller-based SMS gateway information. The study tested are simulated in the laboratory with electronic testing and testing communication systems. The test results showed good performance with the prototype, the results of monitoring CO2 emissions seen huge levels of carbon dioxide (ppm) is proportional to the output voltage (Vout) is generated. The greater the concentration levels of gas detected by the sensor, the output voltage generated will be greater, than that difference or distinction ADC output between the measured and calculated because of several errors, such as error output ADC ± 2 bits, error rounding conversion of ADC to volt. The measurement results are different, in the closed and open area refers to the measurement parameters are displayed on an alphanumeric display. Measuring system can transmit data via SMS information system with an average response time of less than 1 minute, it depends on the quality of the signal and traffic data from a provider by the user.

Abstract

This study aims to obtain the digital image encryption algorithm with a simple but secure process, fast and efficient computing resources. The algorithms developed in this study were super-encryption algorithm that combines two of cipher called Playfair cipher and the Vigenere cipher. To improve security, a keystream generator was used to randomize the order of the next key in Vigenere cipher. In order to evaluate performance, the proposed algorithm was measured through a series of tests. These tests were implemented with Matlab included visual test and histogram analysis, information entropy, encryption quality, correlation analysis, and also time analysis. The test results show that cipher  image looks visually random.The image histogram of the plain image and cipher image also seen a significant difference between the two of them. Testing was also performed on mobile phones with Symbian and BADA operating system based on Java Micro Edition Programming. Trial results show that the algorithm was require less computational resources; with average time for image encryption is 3.76 seconds, and the average time  for image decryption is 0.97 seconds. The new proposed image encryption scheme has satisfactory security which makes it a potential candidate for encryption of image data. Keywords:  Image encryption, Vigenere cipher, Playfair cipher, Security test DOI: http://dx.doi.org/10.11591/telkomnika.v10i4.875
