If you ask me for tool, I don't know how you would use it or not but Elvior TestCast is a TTCN3 tool. Which compiles TTCN-3 code and used for conformance testing. You have to first write the MAC code in TTCN-3 which is very simple to write. The quality of this tool is you will get the logs in different formats like grphical, tabular and text. I have used it once. You can go for it. Rest i am not sure about your exact match.

Logs i don't have. Might someone else can help you for this.

Don't know about the tool but you can find intermediate derived Keys and input parameter being used to generate CMAC from the UE logs.
I had come across the integrity check failure in UE, so digged this way.

I know that once the security has been established for the NAS signalling connection, the MME will not process any NAS signalling messages unless they have been successfully integrity checked by the NAS. Is there any scenario where the Tracking Area Update Request sent by the ue will not be integrity protected but still it is processed at the mme and a proper response is given to ue .?
