摘要： A method comprising the use of a bootstrapping protocol to define a security relationship between a first server and a second server, the first and second servers co-operating to provide a service to a user terminal. A bootstrapping protocol is used to generate a shared key for securing communication between the first server and the second server. The shared key is based on a context of the bootstrapping protocol, and the context is associated with a Subscriber Identity Module (SIM) associated with the user terminal and provides a base for the shared key. A method of the invention may, for example, be employed within a computing/service network such as a “cloud”, and in particular for communications between two servers in the cloud that are co-operating to provide a service to a user.

摘要： In one aspect, a new radio protocol architecture is proposed. The proposed architecture is applicable to wireless networks such as a wireless metropolitan area network (WMAN). In the new architecture, there is a clear- cut separation of control, management, and data planes. New control service access points (SAP) are introduced to allow interaction between the protocol layers of the architecture. Also, data SAPs are introduced between the protocol layers. The layer separation idea extracts the functionalities of the architecture and grouped into MAC CPS-H (common part sublayer - high) and MAC CPS-L (common part sublayer - low). Further, a new concept of 'control information base' (CIB) is introduced.

摘要： An authentication server and a system and method for managing cryptographic keys across different combinations of user terminals, access networks, and core networks. A Transformation Coder Entity, TCE, (25) creates a master key, Mk, which is used to derive keys during the authentication procedure. During handover between the different access types, the Mk or a transformed Mk is passed between two authenticator nodes (42, 43, 44) that hold the key in the respective access networks when a User Equipment, UE, terminal (41, 51, 52, 53) changes access. The transformation of the Mk is performed via a one-way function, and has the effect that if the Mk is somehow compromised, it is not possible to automatically obtain access to previously used master keys. The transformation is performed based on the type of authenticator node and type of UE/identity module with which the transformed key is to be utilized. The Mk is never used directly, but is only used to derive the keys that are directly used to protect the access link.

摘要： The present invention relates to fraud prevention and authentication of a device to a user. The method of authenticating a personal device (210) according to the invention comprises a set up sequence (305-310), wherein at least a first preferred output format is selected by the user, and a device configuration verification sequence (315-355). In the device configuration verification sequence a checksum is calculated and converted to a user friendly output format based on the user selected preferred output format. In addition the checksum may be calculated based on variable, and user selectable, keying material. The personal device (210), after being authenticated according to the above, may be used to authenticate a second device (215).

摘要： A method of authenticating a mobile node to a communication system is provided, the communication system comprising a plurality of access nodes, the method comprising the steps of (a) generating a numerical chain comprising a series of values using a oneway coding function such that a given value within the chain is easily obtainable from a subsequent value, but the subsequent value is not easily obtainable from that given value; (b) sending a value from the first numerical chain from the mobile node to an access node to which the mobile node wishes to attach; and (c) using the sent value at the access node to authenticate the mobile node.
