Abstract: In some examples, an access point (AP) receives, from a wireless device during a pre-associated state between the AP and the wireless device, a request, a first value, and an encrypted version of the first value. The AP sends, to the wireless device during the pre-associated state, an encrypted version of a second value relating to an encryption key that is based on the first value, and a response to the request, the response encrypted using the encryption key.

Abstract: The present disclosure relates to methods and apparatus for flexible, security context management during AMF changes. One aspect of the disclosure is a mechanism for achieving backward security during AMF changes in idle mode. Instead of passing the current NAS key to the target AMF, the source AMF derives a new NAS key, provides the new NAS key to the target AMF, along with a key change indication indicating that the NAS key has changed. The target AMF sends the key change indication to the user equipment.

Abstract: The invention relates to a method and a system for networking. The method includes: in response to the terminal entering an effective communication range of a first NFC sensing device in a first router, interacting with the first NFC sensing device, so that the first router or the terminal obtains key information, in which the key information is configured for networking the first router and a second router; and in response to the terminal entering an effective communication range of a second NFC sensing device in the second router, writing the key information into the second NFC sensing device. The invention may construct the networking among the designated routers with the NFC sensing devices via the terminal.

Abstract: A method and apparatus provides a communication connection between a user equipment and a network entity including a plurality of radio bearers having security keys. A connection reconfiguration message is received (1002), which identifies bearer specific changes to be made to a subset of radio bearers including less than all of the plurality of radio bearers, that impact the security keys being used by the subset of radio bearers, where the connection reconfiguration message includes a bearer identification field that identifies the radio bearers included in the subset and a chaining counter. The requested changes are applied (1004) to the subset of radio bearers associated with the bearer identification field without resetting the communication connection with the communication network.
