A secure communication session is established between a first device and a second device, by generating, in the first device, a first secret key to be utilized for communication sessions with other devices. The second device requests to establish a first communication session with the first device, and the second device generates a second secret key corresponding to the first secret key of the first device. The second device stores the generated second secret key in a non-volatile memory of the second device, the second secret key being stored in the non-volatile memory in association with an identifier of the first device. Finally, a secure communication session is established between the first and second devices utilizing the first and second secret keys.
