초록 ▼

The use of stolen mobile identification number (MIN) and electronic serial number (ESN) information to fraudulently place wireless calls is prevented by having the switches of multiple wireless carriers forward or direct, over a telephone connection, all calls placed from selected MINs to a central authentication platform that serves the multiple wireless carriers. The central authentication platform engages in a so-called “challenge-response”authentication with local processors that are interfaced to the wireless telephones from which non-fraudulent calls originate. The challenge-response authentication uses a shared secret key (S-Key) that is not broadcast over the interface, thus preventing the key from being “stolen”. A call from a wireless telephone that is not interfaced to a local processor capable of successfully completing the challenge-response authentication is blocked, while a call from a wireless telephone having a local processor capable of successfully completing the challenge-response authentication is completed to the number desired by the customer. Advantageously, since the central authentication platform serves multiple wireless carriers, the need for one wireless carrier to access the database of another is alleviated and the expense of providing additional security is reduced.

대표청구항 ▼

A method for use in completing calls from first and second wireless telephones each having a MIN, said wireless telephones being served by respective first and second wireless carriers, the method comprising the steps of: receiving at first and second mobile switching centers belonging, respectively, to said first and second wireless carriers, requests for completion of a wireless call from each of said wireless telephones; establishing with an authentication platform, from each of said first and second mobile switching centers, respective first and second voice channel telephone connections, said authentication platform serving said first and second wireless carriers, if said first and second requests originated from wireless telephones belonging to a group of predetermined MINs; supplying to said authentication platform said MINs of said first and second wireless telephones, said MIN of said first wireless telephone being supplied over said first telephone connection and said MIN of said second wireless telephone being supplied over said second telephone connection; transmitting respective challenges from said authentication platform to each of said first and second wireless telephones, via said first and second telephone connections and said first and second mobile switching centers of said first and second wireless carriers, each of said challenges being developed by said authentication platform from respective secret keys stored therein in association with said respective MINs of said first and second wireless telephones; and denying, by said authentication platform, said first or said second call requests for which a proper response to its respective challenge is not received.
