METHOD AND DEVICES FOR PAIRING WITHIN A GROUP OF WIRELESS DEVICES
First Claim
1. A systen for wireless communication comprising a group of wireless devices and a portable device, each device comprising a radio transceiver for wirelessly exchanging data with the other devices,a first wireless device of the group accommodating a first host function and a second wireless device of the group accommodating a second host function, the first and second wireless devices being the same wireless device or different wireless devices;
- the group of wireless devices sharing first secret data and configured for wireless communication to the first wireless device accommodating the first host function via respective first secure connections based on the first secret data;
the portable device comprising a device communication processor forsetting up a second secure connection with the second wireless device accommodating the second host function using a pairing procedure based on second secret data different from the first secret data,receiving a second instruction via the second secure connection, and, according to the second instruction,setting up a respective direct wireless secure connection with at least one wireless device of the group using a respective pairing procedure based on third secret data, the third secret data differing from the first secret data;
the second wireless device accommodating the second host function comprising a host communication processor forsetting up the second secure connection with the portable device using the pairing procedure based on the second secret data,transferring to the at least one wireless device via the first secure connection a first instruction to apply the third secret data for setting up a direct wireless secure connection with the portable device, andtransferring to the portable device via the second secure connection a second instruction to apply the third secret data, for setting up the direct wireless secure connection with the at least one wireless device based on the third secret data;
at least one wireless device comprising a communication processor forreceiving the first instruction via the first secure connection, and, according to the first instruction,setting up the respective direct wireless secure connection with the portable device using a respective pairing procedure based on the third secret data.

Abstract
System for wireless communication comprises a group of wireless devices (110,120,130,140) that include at least one wireless host device (100) securely connected based on first secret data (240) shared by the group. A second secure connection is set-up between a portable wireless device (200) and a wireless host device based on second secret data (250). At least one of the wireless devices is instructed to apply a third secret data for setting up a direct wireless secure connection with the portable wireless device (200). Also the portable wireless device is instructed via the second secure connection to apply the third secret data for setting up the direct secure connections with the wireless devices based on the third secret data. Finally a respective direct wireless secure connection is set-up between the second device and a respective wireless device based on the third secret data. Advantageously latency is reduced in a secure wireless docking system.
