A secure element of a mobile device receives a first authentication token, which may have an encrypted portion and a non-encrypted portion, from a network gateway device to which the mobile device is connected. The secure element determines whether the first authentication token is valid based on a sequence number included in the first authentication token. If the secure element determines that the first authentication token is valid, the secure element generates a second authentication token that indicates a result of an authentication operation performed by the secure element. The second authentication token is sent to the network gateway device. The secure element derives a pre-shared key using a key derivation function, where the pre-shared key is usable to establish a secure communication channel with the network gateway device.

Device and method for authenticating transport layer security communications

A secure element device for use in a connected device includes a first interface configured to enable communication with a communication module and a second interface configured to enable communication with an action module of the connected device. A processor coupled to the first interface and the second interface, executes a first set of computer-readable instructions, stored in a memory of the secure element device, to authenticate, via the first interface, the connected device on the communication network. The processor also executes a second set of computer-readable instructions, stored in the memory, to perform one or both of (i) obtaining, via the second interface, data from the action module, the data to be transmitted over the communication network and (ii) controlling, via the second interface, the action module to cause the action module to perform one or more operations based on an instruction received over the communication network.

Method and apparatus for operating a connected device using a secure element device

Methods, systems, and media for monitoring updates on a data carrier module include processes of initializing the mobile device to communicate on a telecommunications network, updating data files on the data carrier module, and reinitializing the mobile device to communicate on the telecommunications network. Initializing the mobile device includes storing a list of version numbers for monitored data files and the monitored data files from the data carrier module in a cache. Updating includes updating the version number of a monitored data file when the content of the monitored data file is updated on the data carrier module. Reinitializing the mobile device includes determining whether the version numbers of any monitored data files have changed, copying updated monitored data files from the data carrier module to the cache in response to determining that the version numbers of such data files changed, and loading the monitored data files from the cache.
