TITAN.IUM
DATA SHEET

Titan.ium’s Ut-Proxy is a next-generation Subscriber Self Administration (SSA) that allows the UE to conduct configuration of different application services in whole or part of the service setting. The Ut-Proxy solution provides two functions: the Bootstrapping Function (BSF) and the Ut-Authentication Proxy (Ut-AP) function in one single application. BSF is hosted in a network element under the control of an MNO, i.e., H-PLMN. BSF, HSS, and UEs participate in GBA, in which a shared secret is established between the network and a UE by running the bootstrapping procedure. Ut-AP acts as an Authentication Proxy and authenticates the IMS user by using the bootstrapped security association retrieved from BSF.
