With the rapidly advancing technology of today, exchange of information and data is a very pertinent matter. The world has just recently witnessed the effects of information leakage through the issue of WikiLeaks. There are huge amounts of data being shared over different platforms nowadays. Global System for Mobile Communication (GSM) is one of the most reliable platforms known to and used by almost all people in the world for text as well as voice communication. With the tools like Android Studio and NetBeans available, it is now possible to encrypt the text that has to be sent over the GSM, so that it can be decrypted at the other end of the communication path. However, the encryption and decryption of voice being transmitted over the GSM network still remains a question. In the domain of real time voice encryption, much of the work being carried out pertains to the voice being exchanged through the Internet Protocol. As compared to the Voice over Internet Protocol (VoIP), voice over the GSM network has not seen much research work related to its security aspects. The purpose of this paper is to document the results of a project aimed at developing a platform for mobile phones in order to communicate over the GSM network in a secure manner. The most suitable method for achieving the above mentioned objective is to use an open source Operating System (OS), so that the source code is easily accessible and usable. In this paper, the Android OS will be under discussion, which is compatible with all the Android mobile phones. In this way, the maximum number of mobile phone users can be benefitted because Android cell phones are being widely used nowadays. The use of cryptographic algorithms for securing the voice communication over the GSM network is also a part of this paper. The work revolves around the Java programming language since the Android application development has been carried out in Java through the use of Android Studio. Also, NetBeans has been employed for developing algorithms for voice encryption

Abstract   Communication is very important and a success factor of the system at the company. Communication can be done using telephone media and internet media. PT. Interdev Prakarsa has several branches and communication between branches is still done using telephone media, and it is very costly for the company especially since the company is already using internet media in the network. The solution to this problem in this study was designing an internet-based technology as communication between branches, the technology is called Voice over Internet Protocol (VoIP) with an open source operating system and an open source firewall that was Shorewall. Result showed that after installation and testing, this firewall reliable enough to overcome the problem of attack problems from outside. The results of VoIP tightening on service quality found that the application of VoIP did not consume a lot of CPU Benchmarks, i.e. only 0.80 to 1.35 per cent. The bandwidth used is also very small between 86 to 86.8 kbps for incoming calls and 83.4 up to 84.3 kbps for outgoing calls. Communication built between VoIP peripherals has also been tested to run well because the value of delay, jitter and packet loss is included in the good category. Keywords: VoIP, Shorewall, Comunication   Abstrak   Komunikasi pada sebuah perusahaan sangatlah penting, dimana komunikasi menjadi alat ukur keberhasilan sistem di perusahaan tersebut.

Open-Source has not only removed the monopoly of the few technological companies, but has also distributed the knowledge, at no cost. With knowledge moves on from person to person, and each person adds his/her contribution to the past work, a knowledge production chain keeps rolling, greatly reducing the effort to re-invent wheels. It allows the public availability of data and enables the addition, modification, and edition of data more efficiently at a faster pace. Robots, considered as a replacement of man-power are of meticulous interests for researchers in the past few decades. Their immunity to walk and talk more or less like a human is worth praising, but this radical change was not so obvious a decade or two ago before the wide propagation of open-source, the continuous spread of research work around the world allows the brilliant minds to add their pieces to incrementally growing joint efforts. It has revolutionized the robotics from the simple remote-control cars to the self-driven cars. This survey summarizes main stream open source projects emerging in recent years and expects to increase the exposure of existing open source projects and increase the popularity of them, with an intention to further reduce unnecessary effort to re-invent existing systems.
