Title: KEY HIERARCHY FOR NETWORK SLICING
Abstract:
A method is provided for facilitating service-specific security while avoiding a full authentication and key agreement exchange each time a service is activated on a device. Multiple services on a single device and sharing the same session link (e.g., radio link or radio bearer) and the same physical network may nonetheless obtain distinct service-specific network connectivity root keys from which service-specific security/session keys may be derived. In such case, instead of performing a full authentication and key agreement exchange with an operator or provider (e.g., home subscription server or HSS), the device may authenticate a network slice using a security credential established during a prior authentication with another network slice.
