The safest way to protect the next pseudonymous IMSI SMS is a layer of end to |

end encryption from the HLR to the SIM. The existing means for OTA SMS security |
|
| 406 |
(3GPP TS 23.048) provide mechanisms for integrity protection, confidentiality |
|

as well as replay protection and must be implemented when using IMSI |
