    Abstract: A method and apparatus to establish trust between two nodes in a communications network. A first node receives from a network node authentication data unique to the first node, which can be used to derive a compact representation of verification data for the first node. The first node also receives a certified compact representation of verification data of all nodes in the network. The first node derives trust information from the authentication data for the node, and sends to a second node a message that includes the trust information and part of the authentication data. The second node has its own copy of the certified compact representation of verification data of all nodes in the network, and verifies the authenticity of the message from the first node using the compact representation of verification data of all nodes in the network and the received trust information and authentication data.

    Abstract: An IMS system includes an IMS initiator user entity. The system includes an IMS responder user entity that is called by the initiator user entity. The system includes a calling side S-CSCF in communication with the caller entity which receives an INVITE having a first protection offer and parameters for key establishment from the caller entity, removes the first protection offer from the INVITE and forwards the INVITE without the first protection offer. The system includes a receiving end S-CSCF in communication with the responder user entity and the calling side S-CSCF which receives the INVITE without the first protection offer and checks that the responder user entity supports the protection, inserts a second protection offer into the INVITE and forwards the INVITE to the responder user entity, wherein the responder user entity accepts the INVITE including the second protection offer and answers with an acknowledgment having a first protection accept. A method for supporting a call by a telecommunications node.

    Abstract: An authentication method comprises providing a set of N plural number of master keys both to a user terminal (13) and to home network entity (11) and, when performing an authentication key agreement (AKA) transaction for an application, selecting one of the N number of master keys to serve as a master key for use both at the user terminal and the home network entity for deriving further keys for the application. For example, when performing an authentication key agreement (AKA) transaction for a first application, the method involves randomly selecting one of the N number of master keys to serve as a first master key for use both at the user terminal and the home network entity for deriving further keys for the first application; but when 10 performing an authentication key agreement (AKA) transaction for another application, the method involves randomly selecting another one of the N number of master keys to serve as master key for use both at the user terminal and the home network entity for deriving further keys for the another application.

    Abstract: A method in a first user equipment (UE 1) connectable to a second user equipment (UE 2) via a communication network or via a direct radio communication link, of using a direct radio communication link for communication between the UEs is initiated when one of the UEs receives probe signaling information comprising a first probe token via the communication network. The UEs exchange probe signaling messages including a second and/or the first probe token at least partly according to the probe signaling information, such that one of the UEs can compare the probe tokens, generate a probing report and provide the probing report to the communication network, or to the opposite UE for evaluation in case of a successful comparison and such that a direct radio communication link can be used for communication with UE 2 in response to receiving instructions to use the second direct radio communication link from the entity by which the probing report was evaluated.

    Abstract: A method for estimating the strength of a graphical password comprising two or more segments is disclosed. In some embodiments, this advantageous solution is achieved by implementing a multi-step process. In one step, the data processing system applies a first operation on a first segment to produce a transformed segment. In another step, the data processing system performs a comparison operation between the transformed segment and a second segment. In another step, the data processing system performs a penalty operation with respect to the first segment based on an outcome of the comparison operation. The penalty operation includes one or more of (1) calculating a penalty value, wherein the penalty value may be used in calculating a value representing the strength of the graphical password; and (2) disregarding the first or the second segment when calculating the value representing the strength of the graphical password.
