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; transmitting by the second communication device to the first communication device K′ and R2 to generate K″ using R2 and K′.

Abstract: The present invention relates to a mobile communication device for communicating with a cellular network by means of a serving base node, the mobile communication device further being connected to a subscriber identity module, the mobile communication device being configured to operate in a power optimization mode wherein the power optimization mode comprises extended paging periods, and the mobile communication device is further configured to set up a communication context with the base node using authentication means of the subscriber identity module, wherein the mobile communication device is further configured, in case of detection of a removal of the subscriber identity module and when the power optimization mode is activated: to send an removal alert message to the serving base node by means of said communication context, afterwards to terminate the communication context.

Abstract: The present invention relates to a method to authenticate a subscriber (IMSIi) within a local network (LNj) comprising preliminary step of deriving a subscriber key (SMKi) in local keys (LKi), one local key (LKiLNj) for each local network (LNj) the subscriber (IMSIi) is authorized to access, provisioning each local network (LNj) the subscriber (IMSIi) is authorized to access with its own local key (LKiLNj). When an authentication is required in a given local network (LNj), an UICC application derives a local key (LKiLNj) in the UICC application of the subscriber (IMSIi) using the network identifier (LNj), the key derivation function (KDF) and the subscriber key (SMKi) and use the derived local key (LKiLNj) in the algorithm to perform local authentication in the local network (LNj).

Abstract: The present invention relates to a method to establish a secure voice communication session between two user equipments with the help of a dedicated Network Application Function (NAF) and at least one Bootstrapping Server Function. A session key is calculated from bootstrapping service derived external or internal NAF keys of the first and the second user equipments. A secured voice communication is established using the calculated session key.
