Introduction At the December 3GPP2 Joint Meeting on M2M SRD (S.P0146-0), the following requirement was agreed SEC-04: cdma2000 networks shall support a mechanism to restrict the use of a cdma2000 M2M access subscription to a specific cdma2000 device or a group of devices Similar requirement is also in 3GPP (see clause of TS ) and various solutions are under study in SA3 group (please refer to sections 5.6 & 7.5 of S )S In this contribution, we propose that TSG-S WG4 initiate work on evaluating potential security solutions to meet this requirement in cdma2000 systems 2

Solutions in SA3 Methods under study in SA3 can be classified into two broad categories : – UE based mechanisms – Network based mechanisms UE based mechanisms has 3 variants Secure Channel pairing USAT application pairing PIN verification pairing – All based on UICC features with varying levels of security – The enforcement of the binding is proposed to be performed by the UICC Management of the IMEI-IMSI pairing info on the UICC & associated overhead is an issue with UICC based solutions Network based mechanisms has 2 variants – IMSI – IMEI binding in HSS/HLR – IMSI – IMEI binding in HSS/HLR enhanced with device authentication – In both methods, the pairing info is stored in an entity in the network (HLR/HSS) and enforcement is performed in the network 3

Solutions for 3GPP2 Applicability of the solutions in 3GPP should be studied in 3GPP2 – the solutions may not be usable in 3GPP2 due to differences between 3GPP & 1x ; for example, OTA management of pairing info on the UICC/R-UIM Attach/Registration, authentication and device identity request procedures Alternatives to the 3GPP approaches should also be studied in 3GPP2 4

Proposal We propose that TSG-S WG4 initiates work on evaluating potential security solutions in cdma2000 systems to satisfy this requirement 5
