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.

摘要翻译：一种确保连接到网络的网络应用功能，NAF和用户设备UE之间的会话的方法。使用通用引导架构，GBA或类似的架构为NAF分配NAF标识符NAF_id，并且在UE和NAF之间建立共享密钥（S7.1）。将包含引导事务标识符的应用请求从UE发送到NAF（S7.2），并且将包括引导事务标识符，NAF_id和从共享秘密导出的信息的认证请求发送到引导服务器功能BSF （S7.4）.BSF和UE通过在密钥导出函数中使用修改参数代替原始参数或除原始参数之外，通过使用修改的参数来确定NAF密钥Ks_NAF，修改的参数从共享密钥和密钥导出函数的原始参数（S7.5）。该NAF密钥从BSF发送到NAF（S7.6），用于保护NAF与UE之间的通信（S7.7）。还提供了在上述方法中用作NAF，UE和BSF的装置。
