A first server exchanges with a second server a master (symmetric) key(s). The first server sends to the first application the master key(s). The second server generates dynamically a first derived key by using a generation parameter(s) and a first master key. The second server sends to the second application the first derived key and the generation parameter(s). The second application generates and sends to the first application a first (key possession) proof and the generation parameter(s). The first application verifies successfully by using the generation parameter(s), the first master key and the first proof, that the first proof has been generated by using the first derived key, generates and sends to the second application a second (key possession) proof. The second application verifies successfully that the second proof has been generated by using the first derived key, as a dynamically generated and proven shared key.

Method for mutual symmetric authentication between a first application and a second application

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).

Method to authenticate a subscriber in a local network

A system and method for transmitting a provisioning dataset from a cellular network to a user equipment. The cellular network includes a plurality of base nodes providing access to the user equipment, a remote provisioning server accessible by the cellular network, and a core network, including at least two network slices. At least one of the network slices includes at least one network node exclusively assigned to the network slice. At least one of the network slices is dedicated for operating a predefined class of user equipment. At least one remote provisioning network slice includes an assigned network node giving access to the remote provisioning server, and at least one base node assigned to the remote provisioning network slice.

Method for remote provisioning of a user equipment in a cellular network

A method, a device and a system for printing a three dimensional object are disclosed. A printing device, as a first device, or a second device stores predetermined data relating to one or several printings. The second device cooperates with the first device. The first or the second device stores a predetermined printing threshold. The first or the second device determines and stores, during a printing of the three dimensional object, at least one current printing progress rate. The first or the second device compares the current printing progress rate to the predetermined printing threshold. As soon as the current printing progress rate is greater than or equal to the predetermined printing threshold, the first or the second device updates the data relating to one or several printings, so as to validate the printing of the three dimensional object.
