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.
