Embodiment Construction

[0031] In the following description, for purposes of illustration and not limitation, specific details are set forth, such as specific architectures, interfaces, techniques, etc., in order to provide a thorough understanding. In other instances, detailed descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description with unnecessary detail. Throughout this specification, the same reference numerals designate the same or similar elements.

[0032] For completeness and to provide a thorough understanding of the present teachings, the Non-Access Stratum (NAS) and Access Stratum (AS) are briefly described first. NAS is a Universal Mobile Telecommunications System (UMTS), e.g. ) and functional layers in the LTE wireless telecommunication protocol stack. This layer is used to manage the establishment of communication sessions and to maintain continuous communication with the UE while the UE is moving. Note that NAS service may include N...

Abstract

A method (30) of establishing a key related to at least two network instances (Slice 1, Slice 2) is disclosed performed in a network node (11; 12). The network instances (Slice 1, Slice 2) are used for serving a communication device (14). The method (30) comprises obtaining (31) a first key (KeNB1; KASME1) relating to at least a first network instance (Slice 1); obtaining (32) a second key (KeNB2;KASME2) relating to an additional network instance (Slice 2); determining (33), based on the first key (KeNB1; KASME1) and the second key (KeNB2; KASME2), a joint key (KeNB_joint; KASME_joint) for use in protecting communication with the communication device (14) on the at least first network instance (Slice 1) and on the additional network instance (Slice 2). A method (40) in a communication device (14), the network node (11; 12), the communication device (14), computer programs and computer program products are also disclosed.

Description

technical field [0001] The technology disclosed herein relates generally to the field of secure communications in communication networks, and in particular to methods performed in network nodes and communication devices to establish keys associated with at least two network instances. The present disclosure also relates to corresponding network nodes, communication devices and related computer programs and computer program products. Background technique [0002] Network slicing is a new concept applied to both Long Term Evolution (LTE) and future fifth generation (5G) Radio Access Technology (RAT) (denoted NX in this paper). In network slicing, logically separate partitions of the network are created, where the partitions address different business purposes. These "network slices" can be logically separated to some degree in order to be seen and managed as their own network. Logical network slicing can enable operators to provision networks on a service basis to meet vario...
