Spanish Chamber of Deputies chooses Bull to design and implement its high-security wireless network

Computers and mobile devices can now be used with total security within the Chamber of Deputies premises

The Spanish Chamber of Deputies (the lower house of the Spanish parliament) has chosen Bull to design and implement a wireless network linking all its sites.

As part of its network infrastructure renovation initiative, the Chamber of Deputies has chosen to install a wireless network so users can access services and applications from any parliamentary site, so enhancing their real mobility. The network can subsequently be re-used for wireless telephony services.

The project was entrusted to Bull, which has designed and implemented the wireless network using Nortel WLAN equipment. Bull’s proposed solution is built on a principle of system redundancy, so that any wireless device can link up to the network via two access points. Fundamental to the whole project is the end-to-end security for the network, which uses data encryption technologies based on industry standards. 

An end-to-end secure network
To ensure the highest level of security for all communications taking place, Bull has installed a solution which allows users to sign-on in total security from different types of devices including laptops, personal digital assistants (PDAs) or mobile phones, thanks to secure WiFi access technologies such as WiFi Protected Access (WPA and WPA2) and Advanced Encryption Standard (AES). These are integrated within other security systems already in place such as the LDAP protocol and the use of verification certificates. The new solution provides an additional level of security, in that data passes from the WiFi network to the local network through firewalls.

With this solution, whenever a user establishes a connection with a point of access, this access point transmits the information to a Wavelength Selective Switch (WSS) security switch which can dialogue with the RADIUS and certification servers. This means that everyone has to pass through the different levels of security, guaranteeing total security for the network.

Not only does the solution proposed by Bull allow users to be completely mobile across all the different locations within the Chamber of Deputies, but it also offers them identical network connection conditions wherever they happen to find themselves.
