METHOD FOR GRANTING A PLURALITY OF ELECTRONIC COMMUNICATION DEVICES ACCESS TO A LOCAL AREA NETWORK

摘要

Method for granting a plurality of electronic communication devices access to a local area network (LAN) via an access point using a single cryptographic key to secure communications exchanged through the LAN. The method comprising an activation phase performed once at initialization of the LAN and an operating phase wherein the electronic communication devices accesses the LAN. The activation phase comprising: providing the cryptographic key in a digital form by the access point; transferring the cryptographic key to a master device, switching the access point into a secure mode in which any further communication with the access point is secured with the cryptographic key. The operating phase comprising: transferring the cryptographic key from the master device to the electronic communication devices. The cryptographic key is converted from its digital form into a graphic form and then transferred in the graphic form to the electronic communication devices during the operating phase.

主权项

1. A master device for granting an electronic communication device access to a local area network via an access point using a cryptographic key to secure communications exchanged through said local area network, said master device comprising:
a communication interface suitable for receiving said cryptographic key in a digital clear form from said access point; a memory for storing said cryptographic key; a central processing unit to convert said cryptographic key from its digital clear form into a graphical form; a dispatching resource suitable for dispatching the graphical form of said cryptographic key to said electronic communication device.
