摘要： Embodiments described herein relate to methods and apparatuses for enabling remote management of a profile in an identity module in an NB-IoT device. A proxy server is configured with access to a database of one or more external identifiers associated with one or more respective NB-IoT devices, wherein the one or more external identifiers are used to address the respective one or more NB-IoT devices via an exposure function in a core network. A method in the proxy server comprises receiving a request to deliver a triggering message to the NB-IoT device, wherein the request comprises a device identifier; determining an external identifier based on the received device identifier; and delivering the triggering message to the NB-IoT device using the external identifier.

摘要： A method is disclosed of a secure component (SC) of a local attestation server (LAS) for populating an enclave associated with the LAS. The SC comprises stored encrypted population information previously received in a data packet and encrypted by an encryption key matching a private decryption key of a trusted platform module (TPM) associated with the LAS. The method comprises receiving a public part of a temporary asymmetric key from the enclave, establishing a secure session between the SC and the TPM, sending (to the TPM by using the secure session) the encrypted population information and the public part of the temporary asymmetric key, receiving (from the TPM by using the secure session) the population information decrypted by the private decryption key and re-encrypted by the public part of the temporary asymmetric key, and transmitting the re-encrypted population information to the enclave. An additional method is also disclosed for enabling the population of the enclave. The additional method comprises receiving control parameters of the LAS, comprising the encryption key matching the private decryption key of the TPM, encrypting population information based on the control parameters and using the encryption key, and sending a data packet comprising the encrypted population information to the SC. Corresponding apparatuses and computer program product are also disclosed.

摘要： The application discloses methods and corresponding systems and network devices and/or nodes for enabling user equipment belonging to a home network to access data communication services in a visited network of a wireless communication system. By way of example, there is provided a method that comprises the step of obtaining at least one cryptographic token originating from a network node of the home network of the user equipment and cryptographically signed by a private key associated with the home network, wherein the at least one cryptographic token represents means for accessing data communication services via user data transport functions of the visited network. The method also comprises cryptographically signing the obtained and signed token by a private key associated with the user equipment to generate a double-signed token, and sending the double-signed token to a network node of the visited network, which validates the double-signed token for enabling the user equipment to access data communication services via the user data transport functions of the visited network.

摘要： There is provided mechanisms for handling instances of a trusted execution environment on an execution platform. The trusted execution environment is associated with a secure cryptoprocessor. The secure cryptoprocessor holds a register. The trusted execution environment is configured to read from and write to the register at a given index i. A method is performed by the trusted execution environment. The method comprises checking, upon start of a new instance of the trusted execution environment, status of the register at the given index i, and wherein, when the register at the given index i has its status set to “undefined”, an internal status value is set to a first value, and else, when a value is read from the register at the given index i, the internal status value is set to a second value based on the read value. The method comprises writing the internal status value to the register at the given index i. The method comprises running the new instance. The method comprises, whilst running the new instance, reading a current value from the register at the given index i. The method comprises enabling the new instance to keep running only when the current value equals the internal status value.
