Abstract:
Aspects of security schemes (e.g., integrity protection, encryption, or both) are described. A measure of access stratum security can be realized without overhead associated with establishing and/or maintaining the per-cellular-device access stratum security context at a Cellular Internet of Things (CIoT) base station (C-BS). A gateway (e.g., a CIoT Serving Gateway Node (C-SGN)) may derive a first key. The first key may be only known to the C-SGN. The C-SGN may derive a second key from the first key and a parameter unique to the C-BS. The C-SGN may also derive a third key from the second key and an identity of a cellular device. The C-SGN may send the second and third keys to the C-BS and cellular device, respectively. Small data messages encrypted and/or integrity protected by the cellular device may be decrypted and/or verified by the C-BS.

Claim (Index 1):
A method of communication, comprising:\n obtaining, at a network node, a first key; obtaining, at the network node, a second key that is based on the first key and a parameter unique to a radio access network (RAN) node; provisioning, by the network node, the second key to the RAN node; obtaining, at the network node, a third key based on the second key and a parameter unique to a cellular device; and provisioning, by the network node, the third key to the cellular device.
