摘要： A method of securing a session between a Network Application Function, NAF, and a User Equipment, UE, connected to a network. The NAF is assigned a NAF identifier, NAF_id, using the Generic Bootstrapping Architecture, GBA, or a similar architecture and a shared secret is established between the UE and the NAF (S7.1). An application request containing a bootstrapping transaction identifier is sent to the NAF from the UE (S7.2) and an authentication request comprising the bootstrapping transaction identifier, the NAF_id, and information derived from the shared secret is sent to a Bootstrapping Server Function, BSF, from the NAF (S7.4).The BSF and the UE determine a NAF key, Ks_NAF, by using a modified parameter in place of or in addition to an original parameter in a key derivation function, the modified parameter being derived from the shared secret and the original parameter of the key derivation function (S7.5). This NAF key is transmitted from the BSF to the NAF (S7.6) and used to secure communications between the NAF and the UE (S7.7). Also provided are apparatus to act as a NAF, UE, and BSF in the method above.

摘要： A method of controlling access to content comprises receiving, at a domain gateway (3) of a domain (4), a request from a device (5) in the domain for access to the content. It is determined at the domain gateway whether the number of devices in the domain currently accessing the content is equal to a specified maximum number of devices that may simultaneously access the content. The maximum number of devices that may simultaneously access the content is independent of the number of devices in the domain. If the determination is that the number of devices in the domain currently accessing the content is less than the specified maximum number the request is allowed, otherwise it is refused.

摘要： Methods and apparatus for encrypting and storing data. The methods and apparatus provide different levels of security and usability. The methods and apparatus generate two or more keys based on a shared secret made available to a user equipment and a server. The two or more keys comprise at least one perfect forward secrecy key, and at least one limited forward secrecy key. The methods and apparatus encrypt data using at least one of the two or more keys. The methods and apparatus store the encrypted data in a memory of the user equipment and/or transmit the data from the user equipment to the server.

摘要： The present invention relates to a method of key management and to an apparatus (200) of communication network (100) comprising a plurality of groups (141, 142, 143), each group (141) including one or several members (132A, 132B, 132C) authorized to have access to key-protected services provided by the apparatus. According to the method, it is determined when a member (132A) starts a switching action from one service to another and it is determined a time dependent quantity starting from the switching action. The method further comprises, determining that the member (132A) is a member of a switching group (150) when the quantity is less thana threshold value, and when the quantity is larger than the threshold, determining that the member (132A) has decided to join a new group(142), and changing the appropriate access key(s).
