Claim 7:
8. The method of claim 1, further comprising:
receiving at the SSZ function an SSZ communication registration request, the SSZ communication registration request received from a first network function (NF), the SSZ communication registration request comprising an identifier (ID) of the first NF, a first slice ID, a second NF ID, a second slice ID, and a registration communication parameter;
determining by the SSZ function whether a registration criterion is met by determining whether the secure storage function includes a first slice registration association between the first slice and the SSZ, a second slice registration association between the second slice and the SSZ, a first NF registration association between the first NF and the SSZ, and a second NF registration association between the second NF and the SSZ;
if the registration criterion is not met, sending by the SSZ function a first SSZ registration violation message to a system administration function executing on a second network server, the first SSZ registration violation message including information relating to the SSZ communication registration request and the SSZ function;
if the registration criterion is met, determining by the SSZ function whether a security criterion is met by determining whether the registration communication parameter complies with the SSZ security profile of the SSZ, a first slice security profile of the first slice, and a second slice security profile of the second slice that are stored in the secure storage function;
if the security criterion is not met, sending by the SSZ function a second SSZ registration violation message to the system administration function; and
if the security criterion is met:
storing in the secure storage function a communication registration association comprising the first NF ID, the first slice ID, the second NF ID, the second slice ID, and the registration communication parameter; and
sending by the SSZ function an SSZ communication registration response to the first NF.
