Method and arrangement for providing a wireless mesh network

A method for providing a wireless network comprising:

• a first communication device communicating with an authentication server in accordance with Extensible Authentication Protocol (“EAP”) in a first authentication communication, the first communication device communicating with the authentication server in the first authentication communication as an authenticator defined according to EAP protocol;
• the authentication server generating first encryption information, first policy information and second policy information in response to the first authentication communication and transmitting the first encryption information, first policy information and second policy information to the first communication device;
• the first communication device sending the second policy information to a second communication device, at least the second policy information being protected by a cryptographic checksum;
• the first communication device communicating with the second communication device in accordance with EAP in a second authentication communication, the second authentication communication being based on the second policy information, the first communication device communicating with the second communication device in the second authentication communication as a supplicant defined according to EAP and the second communication device communicating with the first communication device during the second authentication communication as an authenticator defined according to EAP and the second communication device not communicating with the authentication sever during the second authentication communication such that the second communication device does not have a link with the authentication server during the second authentication communication, the second authentication communication being processed based on at least a portion of the first encryption information;
• and
• the first and second communication devices exchanging communication information via a protected communication after the first and second authentication communications are completed;
• and
• wherein the first encryption information is transmitted to the first communication device via a first EAP success message that comprises the first encryption information and wherein the second communication device receives a second EAP success message that comprises second encryption information.
