Abstract
Techniques are disclosed relating to using a device to gain access to another system. In some embodiments, a first mobile device performs a pairing operation with a control unit that controls access to a system, the pairing operation including the first mobile device establishing a first cryptographic key with the control unit. The first mobile device receives a request to enable a second mobile device to communicate with the control unit, and in response to receiving the request, the first mobile device generates a second cryptographic key from the first cryptographic key. The first mobile device provides the second cryptographic key to the second mobile device. The second mobile device is configured to send a beacon including a payload encrypted with the second cryptographic key, and the encrypted payload is usable to authenticate the second mobile device to the control unit.
