摘要： A method for establishing a security association between a client and a service node for the purpose of pushing information from the service node to the client, where the client and a key server 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： Disclosed is a method in a network node (106) for establishing neighbor cell relations in a wireless network for a source cell (107) served by the network node (106). The method comprises establishing (34) a temporary neighbor cell relation for a received unknown neighbor cell identification; verifying (36) validity of the temporary neighbor cell relation, and establishing (38) a permanent neighbor cell relation based on the established temporary neighbor cell relation, if the temporary neighbor cell relation is found valid, thus avoiding that a false neighbor cell identification results in a faulty permanent neighbor cell relation. Disclosed is also a corresponding apparatus in a network node for establishing neighbor cell relations in a wireless network.

摘要： An improved approach to mobile device capability management is described herein where a capability management device is provided at a mobile communication network. Upon change of a mobile device capability, a related notification is sent to the capability management device which applies a policy decision whether to track the capability change at the network side or not. Should the decision be ‘yes’, the capability management device starts a device management session to collect further information on a mobile device capability change beyond the information made available with the mobile device capability change notification. After retrieval of the mobile device capability change information, the capability management device will update its mobile device capability state accordingly.

摘要： Methods and apparatuses in a client terminal (400) and a web server (402) for enabling safe communication between said terminal and server. When the terminal obtains a web page from the server in a session, the terminal creates a context-specific key, Ks_NAF′, based on one or more context parameters, P1, . . . Pn, pertaining to said session and/or web page. The terminal then indicates the context-specific key in a login request to the server, and the server determines a context-specific key, Ks_NAF′, in the same manner to verify the client if the context-specific key determined in the web server matches the context-specific key received from the client terminal. The context-specific key is thus bound to and valid for the present context or session only and cannot be used in other contexts or sessions.

摘要： A path switch message in a mobile radio access network is protected as the message is sent over a user plane interface that may be insecure (e.g. lacks integrity and/or confidentiality protection). According to the invention a UE provides an AP with a fresh integrity key over an already existing and secure RAN channel enabling AP to use the integrity key to integrity protect information sent to a UPN. Specifically, UE derives locally at least a user plane key K1. The key derivation is done at authentication e.g. when performing an AKA procedure. On the network side CPN derives the same key K1 for delivery to UPN. At handover, the UE generates a fresh integrity key K3 by applying a Key Derivation Function (KDF) with at least the UP key K1 and a nonce, e.g. a sequence number.
摘要翻译：当消息通过可能不安全的用户平面接口（例如，缺乏完整性和/或机密性保护）发送时，移动无线电接入网络中的路径切换消息被保护。根据本发明，UE通过已经存在和安全的RAN信道向AP提供新鲜完整性密钥，使得AP能够使用完整性密钥来完整性地保护发送到UPN的信息。具体地说，UE本地至少导出用户面密钥K1。密钥导出是在认证例如当执行AKA程序时。在网络侧，CPN得到与UPN相同的密钥K1。在切换时，UE通过应用具有至少UP密钥K1和随机数的密钥导出函数（KDF）来生成新的完整性密钥K3。一个序列号。
