System and method for securing a personalized indicium assigned to a mobile communications device
First Claim
1. A mobile communications device comprising:
- a processor configured to control at least one of a plurality of sub-systems for communicating with a network node operable with a wireless network;
the processor further configured to control at least one of the plurality of sub-systems for generating an authentication key for securing a personalized indicium assigned to the mobile communications device, wherein the personalized indicium comprises a Personal Information Number (PIN) that is mapped to at least one identifier associated with the mobile communications device;
the processor further configured to control at least one of the plurality of sub-systems for transmitting a registration request to the network node, the registration request having a registration request payload including the authentication key;
the processor further configured to control at least one of the plurality of sub-systems for receiving a challenge message from the network node, the challenge message generated when the network node detects a change of the IP address associated with the mobile communications device,the processor further configured to control at least one of the plurality of sub-systems for executing a challenge response to the challenge message, the challenge response including an authentication value of a challenge string transmitted in the challenge message, wherein the authentication value is created using the authentication key.
