Abstract
A system for propagating encryption key information between wireless communication devices without the requirement of pairing each and every device. A wireless communication device may be paired with at least one device in a group of devices. When a secure link is established between these devices, a determination may be made as to whether encryption key information should be passed from one device to another. The additional encryption key information may allow a wireless communication device to create a secure link with other devices without having to first establish a trusted relationship (e.g., go through a pairing process) with the other devices.
Claims37
A method, comprising:
- establishing a wireless link with an encountered device;
- determining whether a trusted relationship exists with the device;
- if the device is determined to be a trusted device, establishing a secure link with the device;
- and
- receiving encryption key information from the trusted device for establishing a secure link with at least one other device.
2 more elements
A method, comprising:
- establishing a wireless link with an encountered device;
- determining whether a trusted relationship exists with the device;
- if the device is determined to be a trusted device, establishing a secure link with the device;
- determining if encryption key information for establishing a secure link with at least one other device should be transmitted to the trusted device;
- and
- if it is determined that the encryption key information for establishing a secure link with at least one other device should be transmitted, transmitting the encryption key information to the trusted device.
3 more elements
