System and method for establishing authenticated wireless connection between mobile unit and host

A system for establishing an authenticated wireless communication, comprising:

• a first wireless mobile device including only a data capturing arrangement (“DCA”) as an input device interface with a user thereof;
• and
• a second device receiving an initial signal from the first device to establish a wireless communication, the second device initiating an authentication process,
• wherein the first device obtains a PIN code from the user via the DCA, the PIN code identifying at least one device with which the first device is authorized to communicate, wherein the first and second devices perform a pairing process to compare the PIN code to entries in a database of authorized PIN codes, and wherein, when the pairing process has been successfully completed, the first and second devices generate a link key to establish the authenticated wireless communication.

A wireless mobile device for establishing an authenticated wireless communication with a further device, comprising:

• a processor;
• a wireless communication arrangement;
• and
• a data capturing arrangement (“DCA”) being the only input device interface for a user thereof,
• wherein the processor generates a request for establishing an authenticated wireless communication, the request being forwarded to the further device via the communication arrangement, the communication arrangement receives from the further device a first sample data, compiled from a collection of random data, and a request for second data, the DCA obtaining a PIN code from the user, the PIN code identifying at least one device with which the mobile device is authorized to communicate, the processor generating the second data as a function of the PIN code, the first sample data and the hashing procedure, the second data being provided, by the mobile device, to the further device,
• wherein the further device generates third data as a function of at least one of the authorized PIN codes stored in a database, the second data received from the mobile device and the hashing procedure, and
• wherein, when the second data received from the mobile device matches to the third data, the mobile device and the further device generate a link key to establish the authenticated wireless communication.
