I am developing linux driver for my own PCI device. I am stuck on starting my module:

[14941.205599] mymod321: module verification failed: signature and/or
required key missing - tainting kernel

I have read this how to and this question. But it is useful when build own kernel.

I use Ubuntu 14.4.2 LTE on my PC.

Is there any way to get key pair (*.priv + *.509) from current prebuilt kernel to sign my kernel module? Or do I have to recompile the Ubuntu kernel for a new key?
