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 24):
The apparatus of  claim 20 , wherein the processing circuit is further adapted to:\n negotiate the access stratum security configuration during an initial attach procedure with a radio access network (RAN) node, wherein the access stratum security configuration specifies whether small data messages are sent from the apparatus without security, with integrity protection, with encryption, with integrity protection and encryption, and/or with on-demand integrity protection, wherein integrity protection and encryption are performed using the third key.
