1. A wireless device of a wireless communication system for supporting verification of a device category of the wireless device, the wireless device comprising:
a processor and a memory, the memory containing instructions executable by the processor whereby the wireless device is configured to:
receive from a network node a verification message including a random bit sequence;
calculate a verification signature from the random bit sequence by using a verification function assigned to the device category; and
transmit the calculated verification signature to the network node in an uplink message of a random access procedure or in the first uplink message following a random access procedure so as to allow verification of the device category using the verification signature at a network node;
wherein the device category is associated with a security level or priority level shared by a group of wireless devices.
