摘要： A security key, K_eNB, for protecting RRC/UP traffic between a User Equipment, UE, (11) and a serving eNodeB (12) is established by a method and an arrangement in a Mobility Management Entity (13), MME, and in said UE (11), of an Evolved Packet System, EPS. The MME and the UE derives the security key, K_eNB, from at least an NAS uplink sequence number, NAS_U_SEQ, sent from the UE to the MME, and from an Access Security Management Entity-key, K_ASME, shared between the MME and the UE.

摘要： A method for establishing a security association between a client (UE) and a service node (NAF) for the purpose of pushing information from the service node to the client, where the client and a key server (BSF) share a base secret. The method comprises sending a request for generation and provision of a service key from the service node to a key server, the request identifying the client and the service node, generating a service key at the key server using the identities of the client and the service node, the base secret, and additional information, and sending the service key to the service node together with said additional information, forwarding said additional information from the service node to the client, and at the client, generating said service key using the received additional information and the base key. A similar approach may be used to provide p2p key management.

摘要： A tamper-resistant security device, such as a subscriber identity module or equivalent, has an AKA (Authentication and Key Agreement) module for performing an AKA process with a security key stored in the device, as well as means for external communication. The tamper-resistant security device includes an application that cooperates with the AKA module and an internal interface for communications between the AKA module and the application. The application cooperating with the AKA module is preferably a security and/or privacy enhancing application. For increased security, the security device may also detect whether it is operated in its normal secure environment or a foreign less secure environment and set access rights to resident files or commands that could expose the AKA process or corresponding parameters accordingly.

摘要： An encrypted service key, MSK, is sent from an access server, BM-SC, of a communications network to a user terminal, ME. The user terminal is preferably a mobile phone. The encrypted service is passed to a secure module of the user terminal, UICC (step 2). The secure module has access to a decryption key, MUK, for decrypting the encrypted service key. An acknowledgment of receipt of the service key is sent from the user terminal to the access server (step 3). The access server authenticates the acknowledgment and sends a return acknowledgment to the user terminal (steps 4 and 5). The secure module of the user terminal then authenticates the return acknowledgment before allowing the user terminal to use the service key. The service key may be used to decrypt a traffic key (steps 6 and 7), which can in turn be used to access broadcast or multicast data. Preferably, the user terminal is not charged for provision of the service key until the access server receives the acknowledgment from the user terminal. A shared symmetric key, MUK (agreed in step 1), may preferably be used to encrypt and decrypt the service key and to authenticate both acknowledgments.

摘要： Methods and apparatus in a fifth-generation wireless communications, including an example method, in a wireless device, that includes receiving a downlink signal comprising an uplink access configuration index, using the uplink access configuration index to identify an uplink access configuration from among a predetermined plurality of uplink access configurations, and transmitting to the wireless communications network according to the identified uplink access configuration (18210). The example method further includes, in the same wireless device, receiving, in a first subframe, a first Orthogonal Frequency-Division Multiplexing, OFDM transmission formatted according to a first numerology and receiving, in a second subframe, a second OFDM transmission formatted according to a second numerology, the second numerology differing from the first numerology (18220). Variants of this method, corresponding apparatuses, and corresponding network-side methods and apparatuses are also disclosed. (Figure 8)

摘要： Un método para operar un nodo en una red de comunicación, comprendiendo el método: recibir (901) una petición desde un primer nodo de acceso de radio en la red de comunicación para información en un segundo nodo de acceso de radio en la red de comunicación, refiriéndose la información a si una primera clave base que se utilizó para determinar una primera clave de encriptación para encriptar comunicaciones entre un dispositivo de comunicación y el primer nodo de acceso de radio puede utilizarse para determinar una segunda clave de encriptación para encriptar comunicaciones entre el dispositivo de comunicación y el segundo nodo de acceso de radio; determinar si la primera clave base puede utilizarse por el segundo nodo de acceso de radio, en donde el paso de determinar (901) comprende determinar que la primera clave base puede utilizarse por el segundo nodo de acceso de radio si el primer nodo de acceso de radio y el segundo nodo de acceso de radio son parte de la misma zona de seguridad, en donde el primer nodo de acceso de radio y el segundo nodo de acceso de radio son parte de la misma zona de seguridad si el primer nodo de acceso de radio y el segundo nodo de acceso de radio: (a) están funcionando como máquinas virtuales separadas en el mismo equipo físico informático; (b) son dos contenedores dentro de la misma máquina virtual; (c) están implementados en placas en el mismo estante físico; (d) se determina por una política de seguridad que pertenecen a la misma zona de seguridad; o (e) están localizados físicamente en el mismo lugar; y enviar (903) información en el segundo nodo de acceso de radio al primer nodo de acceso de radio, indicando la información si la primera clave base puede utilizarse por el segundo nodo de acceso de radio.
