1. A system comprising:
a processor, a computer readable storage medium, and program instructions stored on the computer readable storage medium, the program instructions executable to cause a mobile computing device to;
contact a mobile device network with a request to connect to the mobile device network;
conduct an interactive credential issuance protocol with an Issuer of the mobile device network to generate an unlinkable anonymous credential;
connect to the mobile device network based on a Verifier of the mobile device network verifying the computing device using the unlinkable anonymous credential; and
store a temporary mobile subscriber identity (TMSI) assigned to the mobile computing device by the mobile device network, wherein the TMSI is filled with a null value, the null value indicating to the mobile device network that anonymous handover procedures are to be implemented.
