Abstract

Abstracts: The authors conducted a study on wiretapping in computer networks because of it is very disturbing security and comfort in the surf. Therefore the writer create a proxy tunnel software with symmetric and asymmetric encryption as a security agent that encrypts data communications conducted. Forms of research that the author did was experimental data collection techniques onegroup posttest-pretest, the authors study variable is the security of data packets transmitted between website and browser. Design method used is the Extreme Programming with 4 ways to apply the practical development of XP, namely coding, testing, listening and designing. The result is a software design software called "Crypto Tunnel Proxy", according to the function of encryption, tunneling and proxy. The software engineering author uses Visual Basic 6.0 and uses 2 types of encryption, namely symmetrical and asymmetrical. The authors also apply the hash function as a fingerprint or fingerptint of keys that are sent. This application can improve security in computer networks. By encrypting all data packets between the browser and the website are symmetrical and asymmetrical. Tests conducted with several commonly used browsers.Keywords: RC4 and RSA Encryptiom, Tunneling, Proxy

Abstract

Sending text messages is done on a smartphone device is basically the text message delivery without doing a safeguard against the content of the messages sent, so that when it is done tapping against the Groove pengirimanya then intercepted text messages can be directly read by the tappers. For that it needs the software as a specific encoding method support so that the message sent is secure. This research uses the form of research studies, literature research method using Research & Development (R & D). As for the technique of data collection using the study documentation and observation to acquire the theory and algorithm rijndael rc6 algorithm. While the method of software design using Rapid Application Development (RAD). The design of software using the java programming language. The results of this design generates a software named "Sms Encryption". Encryption software sms using the rc6 algorithm and rijndael has been executed and in accordance with the expected user. With the software, the confidentiality and authenticity of the information in the form of a text message will be more awake.
