Abstract
A process for securely pairing devices. A host device receives an input indicating a user credential for logging into the host device and initiates a scanning process for discovering target devices available for pairing with the host device. During the scanning process, the host device receives wireless pairing information from a target device. The wireless pairing information includes a unique device identifier associated with the target device and an electronic signature generated as a function of a signature key stored at the target device and the unique device identifier. The host device compares the electronic signature with a run-time signature generated at the host device as a function of the user credential received at the host device and the unique device identifier. The host device then initiates a pairing process to establish a short-range communication link with the target device when the electronic signature matches with the run-time signature.
