Secure WIFI portals in WIFI4EU environment
| Resumo: | As hotspot networks are increasingly present and used, the amount of sensitive information that is transmitted in this type of network and the fact that users might not be trustworthy leads to the need for existence of security mechanisms that can guarantee, at least, confidentiality and integrity of the users’ transmitted data, as well as the authentication of these networks in order to avoid malicious ones. The majority of public hotspots work based on captive portals and require "authentication", which is not always a secure one (through a captive portal) however, captive portals can be explored in order to be used in conjunction with different technology to provide more secure solutions. This works studies the 802.1X architecture and the way it is used, it also studies captive portals and the different ways that public hotspots provide Internet to its users. The goal of this work is to develop an application that will allow users to register themselves in a system, seamlessly provide them with asymmetric credentials and configure a Wi-Fi connection to a secure network. The registration in this system and the download of the application are done through a captive portal. The users can then authenticate in the secure Wi-Fi network that was configured in their devices, this network is an extension of the EAP method, namely TLS, to authenticate the users according to the credentials that were given to them. This network also allows for authentication, authorization and accounting of its users, it will also allow users that registered in a given captive portal to use the network in any place where it is provided. |
