A method of generating a key for D2D communication between a first user equipment and a second user equipment in a first radio access node is disclosed. In an exemplary embodiment, the method may comprise: receiving a request for D2D key generation from the first user equipment which is served by the first radio access node; determining whether the second user equipment is served by the first radio access node; when it is determined that the second user equipment is served by the first radio access node, generating a first random number and a second random number; generating a first D2D key based on the first random number and a second D2D key based on the second random number; sending the first D2D key and the second random number to the second user equipment; and sending the second D2D key and the first random number to the first user equipment; and when it is determined that the second user equipment is not served by the first radio access node, determining a second radio access node which serves the second user equipment; generating a first random number; generating a first D2D key based on the first random number; sending the first D2D key to the second radio access node; receiving a second D2D key from the second radio access node; and sending the second D2D key and the first random number to the first user equipment.

Method and device of generating a key for device-to-device communication between a first user equipment and a second user equipment

A fast-accessing method may comprise: establishing a first security connection between a first network node and a user equipment; obtaining first information from a second network node, wherein the first information comprises at least one of system information of the second network node and an identifier of a security algorithm selected by the second network node for the user equipment; providing second information to the second network node, in response to an indication of the second network node from the user equipment, wherein the second information comprises security information related to the user equipment; and sending the first information to the user equipment for establishing a second security connection between the user equipment and the second network node.

Fast-accessing method and apparatus

Methods and apparatus are provided for differentiating security configurations in a radio local area network. A method can comprises: at a base station, sending a handover request to a local access point for initiating a handover of a user equipment from the base station to the local access point, the handover request comprising an indication of a scheme of security configuration to be used for protecting a communication between the base station and the user equipment. The method can further comprise, at the base station, forwarding to the user equipment a handover command received from the local access point, wherein the indication is comprised in the handover command by the local access point. The method can further comprise communicating with the user equipment according to the scheme of security configuration after the user equipment is handover to the local access point.

Methods and apparatus for differencitating security configurations in a radio local area network

A method for diverse security handling may comprise: maintaining a first connection between a user equipment and a first network node, and a second connection between the user equipment and a second network node which has a third connection with the first network node; setting an indicator in a packet to indicate whether a destination of user data in the packet is the first network node or the second network node; and transmitting the packet from the user equipment to the first network node via the first connection.

Method and apparatus for diverse security handling in an enhanced local area network

Methods and apparatus are provided for securing device-to-device communications. A method can comprise: at an access network apparatus, obtaining from a core network apparatus and storing a first key shared between a first user equipment and the core network apparatus for device-to-device communications of the first user equipment; receiving from a second user equipment, a request for generating a second key for a device-to-device communication between the first user equipment and the second user equipment; in response to the request, generating the second key based on the first key and security parameters; and sending the second key to the second user equipment.

Methods and apparatus for generating keys in device-to-device communications

Provided are a method, a corresponding apparatus and a computer program product for performing a group authentication and key agreement procedure. A method comprises initiating, by a master device in a group of devices, a group authentication and key agreement procedure towards an authentication entity, wherein a shared group key is defined for use in the group authentication and key agreement procedure; performing mutual authentication between the master device and the authentication entity based upon the shared group key; and performing mutual authentication between the authenticated master device and other devices in the group based upon the shared group key for completion of the group authentication and key agreement procedure. With the claimed invention, the impact of the signaling overhead on a network can be significantly decreased without substantive modification to the existing architecture of the network.

Performing a group authentication and key agreement procedure

The invention relates to a method comprising initiating a session from a subscriber terminal, wherein the subscriber terminal does not comprise a specific user identification module, and authenticating the session based on a temporary identification of the subscriber terminal, by using a procedure performing a server authentication and avoiding a client authentication.
