摘要： A method may be provided at a wireless terminal to support communications with a network node of a wireless communication network. An IKE SA may be initiated to establish a NAS connection between the wireless terminal and the network node through a non-3GPP access network and a non-3GPP interworking function network node. After initiating the IKE SA, an IKE authorization request may be transmitted through the non-3GPP access network to the N3IWF network node, with the IKE authorization request including an identifier of the wireless terminal. An access network key may be derived for the NAS connection through the non-3GPP access network at the wireless terminal, with the access network key being derived based on a NAS count for the wireless terminal and an anchor key. An IKE authorization response corresponding to the IKE authorization request may be received.

摘要： A method performed by a target network node for interworking handover from an evolved packet system, EPS, to a fifth generation system, 5GS, in a mobile network is provided. The method includes receiving, from a source network node, a determined user plane, UP, encryption policy. The method further includes providing the determined UP encryption policy to a target radio access network node. Corresponding embodiments for methods performed by a source network node and a first target network node are also provided.

摘要： A network node of a mobile communications network may need to generate at least one new Input Offset Value, IOV value, for use in protecting communications between the network node and a mobile station. The network node then associates a fresh counter value with the or each new IOV value; calculates a Message Authentication Code based on at least the at least one new IOV value, the fresh counter value associated with the or each new IOV value, and a constant indicating that the Message Authentication Code is calculated to protect the new IOV value; and transmits the at least one new IOV value, the fresh counter value associated with the or each new IOV value, and the calculated Message Authentication Code to the mobile station.

摘要： A message authentication code, for a message transmitted and received over a communications network, is formed by applying inputs to an integrity algorithm acting on the message. The inputs comprise: an integrity key; a value indicating a transfer direction; and a frame-dependent integrity input, wherein the frame-dependent integrity input is a frame-dependent modulo count value that also depends on a random value and on a frame-specific sequence number.
