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.

1. A method for granting a plurality of electronic communication devices access to a local area network via an access point using a single cryptographic key to secure communications exchanged through said local area network, said method comprising:
an activation phase performed once during an initialization of said local area network, said activation phase comprising
generating said cryptographic key in a digital clear form by said access point;transferring said cryptographic key in said digital clear form to a master device; andswitching the access point into a secure mode as soon as said cryptographic key has been transferred to the master device, said secure mode being a mode in which any further communication with said access point is secured with said cryptographic key; and an operating phase during which said electronic communication devices get access to said local area network, said operating phase comprising
transferring said cryptographic key from said master device to any of said electronic communication devices; wherein said cryptographic key is converted from its digital clear form into a graphic form by the master device and said cryptographic key is transferred in said graphic form to said electronic communication devices during the operating phase.
