reference, one could pre-provision a random "imsi_pseudo_key" with the SIM |
| 129 | 129 |
card, store it in the pseudo IMSI table in the HLR, and deploy a new encryption |
| 130 | 130 |
key together with each new pseudo IMSI, attached to the SMS. |

### User-configurable minimum duration between IMSI changes |
|
| 133 |
|
|
| 134 |
It may be desirable to let users configure their minimum duration between IMSI |
|
| 135 |
changes. This allows people with a high privacy requirement to switch their |
|
| 136 |
pseudonymous IMSI more often, and it allows the IMSI change to happen less |
|
| 137 |
often if it is distracting to the user. The latter depends on the phone's |
|
| 138 |
software, for example: |
|
| 139 |
* A Samsung GT-I9100 Galaxy SII smartphone with Android 4.0.3 displays a |
|
| 140 |
message at the bottom of the screen for about 5 seconds, but the user |
|
| 141 |
interface remains usable. |
|
| 142 |
* A Samsung GT-E1200 feature phone displays a waiting screen for 16 to 17 |
|
| 143 |
seconds and is unusable during that time. |
