Abstract
This invention related to a method for provisioning a first communication device with a set of at least one credential required for accessing to a wireless network by using a second communication device provisioned with a cryptographic key K also known by the wireless network, the first communication device being associated with a certificate comprising a public key PK, said certificate being stored with an associated private key PrK in said first communication device, the method comprising the following steps: receiving by the second communication device a registration request from the first communication device in order to be provisioned with the set of at least one credential; transmitting to the wireless network by the second communication device the registration request to generate a set of at least one credential associated to the first communication device comprising at least a cryptographic key K″, the wireless network being adapted to generate a first random number R1 and a second random number R2; receiving by the second communication device a response from the wireless network comprising R1 and R2; generating K′ by the second communication device using R1 and K; transmit…
