How UE conceal public - private key pair?

Any SIM Expert here?

I am trying to generate public - private key pair and store it in UDM and SIM card.

But I have a question, how UE will conceal this info?

(IMSI should be concealed and sent to Core).

How UE is aware of these keys?

UE will conceal IMSI by defined algorithm and sent to air interface.

UDM will have set of algorithms which will try and retrieve IMSI.

So when you say algorithm, it’s like milenage or TUAK?

[Prakash_N]

It can be many (I do not remember at this moment).

Hello,
I thing conceal IMSI and securely handle key pairs in UDM and SIM cards, the UE relies on encryption techniques. These keys are managed securely to ensure IMSI protection during transmission to the Core network. The UE is aware of these keys through established protocols that govern authentication and encryption processes.
