Title:
FAST AUTHENTICATION FOR INTER-DOMAIN HANDOVERS
Document Type and Number:
WIPO Patent Application WO/2015/139630
Kind Code:
A3
Abstract:
Fast mobile device authentication can be achieved during inter-domain handovers between administrative domains operating under a federated service agreement using pseudonym identifications (PID). Specifically, the mobile device may derive a PID when obtaining authentication in a first wireless network, and then use the PID to obtain fast authentication in a second wireless network. The PID may be generated during an Elliptic curve Diffie–Hellman (ECDH) authentication procedure using public keys associated with the mobile device and the first wireless network. The PID (or a derivative thereof) may then be provided to an authentication server in a second wireless network for validation. The PID may be validated by the second authentication server via online or offline validation procedures. The PID can also be used as an electronic coupon for accessing the second network.
