Abstract
Hoy en día prácticamente todo el mundo posee un teléfono móvil, son aparatos electrónicos generalmente muy sencillos de utilizar y muy portables (pesan poco, caben en un bolsillo…) lo que hace muy atractivo el desarrollo de aplicaciones móviles. NFC es una tecnología que nos ofreces grandes ventajas como pagar con el móvil sin necesidad de tener llevar dinero encima, simplemente pasando el móvil por el lector. También permite el control de acceso sin necesidad de que haya un guardia de seguridad en la entrada y compruebe si nuestra tarjeta de acceso es válida o no. El elemento seguro que posee el móvil proporciona identificación, pago o almacenamiento de información de manera segura. Otra tecnología muy importante es Bluetooth, que permite un intercambio de datos de forma intuitiva y también segura ya que requiere un PIN. La aplicación desarrollada para el proyecto posee todas estas ventajas: se trata de un móvil con la tecnología NFC que permite la identificación de forma segura y fiable a través del elemento seguro del móvil. Esta aplicación permite la autenticación en distintas ubicaciones de la universidad (despachos, laboratorios, biblioteca...) teniendo almacenado en el elemento seguro el NIA y una clave que se devolverá cifrada para aumentar, todavía más, la seguridad de la aplicación. La aplicación permite recibir información de un lector a través de NFC, el móvil muestra las posibles opciones, se elege la deseada y se envía al lector. Si la opción deseada no requiere autenticación, el lector envía la información al servidor y, si la requiere la solicita. En este último caso el móvil debe acceder al elemento seguro para obtener la contraseña, el elemento seguro la devuelve cifrada, el móvil se la envía al lector y éste al servidor, que comprueba si es válida. Si es correcta se envía la información al móvil, y sino, le indica que la contraseña es invalida. La aplicación también utiliza Bluetooth para enviar a un lector la reserva realizada, con el código y la información de la misma, y de este modo obtener de manera rápida y sin confusiones la tutoría, el libro o el menú reservados. También se puede enviar mediante NFCIP, dependiendo de las tecnologías soportadas por el lector que recibe la reserva. El proyecto tiene una segunda parte, que consiste en una aplicación web cuya función es similar a la del móvil pero sin necesidad de acudir a las distintas ubicaciones de la universidad. Para acceder a la aplicación será necesario un usuario y un password y, en función de si es un alumno o un profesor, se mostrarán unas opciones u otras. __________________________________________________________________________________________________
Nowadays almost everyone owns a mobile phone, electronic devices are generally very simple to use and very portable (low weight, fit in a pocket ...) which makes mobile application development very attractive. NFC is a technology that offers great benefits and pay with your mobile phone without having to carry money, simply swiping a phone over the reader. It also allows control of access without need for a security guard at the entrance to check if our access card is valid or not. The element that owns the mobile insurance provides identification, credit or store information securely. Another important technology is Bluetooth, which allows exchange of data in an intuitive and secure because it requires a PIN. The application developed for the project has all these advantages: it is a phone with NFC technology that allows the identification of safe and reliable through the secure element of the mobile. This application provides authentication in various university locations (offices, laboratories, library ...) . NIA and a key are stored in the secure element and are returned encrypted to increase even more, the security of the application. The application allows a reader to receive information via NFC, the mobile shows the possible options, choose the desired and sent to the reader. If the desired option does not require authentication, the reader sends the information to the server and, if required upon request. In the latter case, the mobile must access the secure element to obtain the password, the secure element returns the information encrypted, the mobile sends it to the reader who sends it to the server, who checks if is valid. If so, the information is sent to your phone, and if not, tells the mobile that the password is not valid. The application also uses Bluetooth to send a reader the booking with the code and the information itself, in order to obtain quickly and without confusion the tutorial, the book or the menu reserved. Bookings can also be sent by NFCIP, depending on the technologies supported by the reader who receives the information. The project has a second part, which consists of a web application whose functions are similar to mobile phone without having to go to different locations of the university. The application access will require a user name and password and, depending on whether a student or a teacher, will show some other options.
