Acesso de área de trabalho remota via aplicação web protegido por criptografia

Abstract

Remote information access is usually cited and the necessity to access systems remotely is in common place nowadays. Users need to execute instructions in remote machines, however it is highly undesirable, and sometimes impossible, to setup a new program at the local machine. Due to this fact, it is interesting to develop a secure access to a remote machine through an internet connection, using a web browser. We aimed to implement a remote desktop sharing software with cryptographically secured communication between client and server. The client side machine can be simple, even without dedicated hardware. However it must have an updated web browser. Initially, a project plan was developed and it served as the basis for implementation. In this step, we employed a spiral development method which started from the design of small prototypes that evolved incrementally until the desired result. The provided service allows the server side desktop to be displayed in a web browser executed in the client machine, whose keyboard and mouse are used to control the server. It is the web browser that provides the connection and viewing. We expected to make it easier and more secure to access a remote desktop without setting up any new application at the local desktop. This idea is useful at workstations or educational facilities, where certain functionalities may not be available, e.g. administrative/root privileges in operating system.
