Abstract
In some embodiments an accelerometer is mechanically coupled to a first device. The accelerometer obtains a vibration profile in response to a relative movement of the first device and a second device. A radio transmits an encrypted version of the vibration profile to the second device and receives an encrypted version of a vibration profile from the second device. A processor sets up a secure channel between the radio and the second device in which to exchange keys with the second device in order to decrypt the received encrypted vibration profile. The processor also decrypts the received encrypted vibration profile in response to at least one of the exchanged keys, compares the transmitted vibration profile with the received vibration profile and allows a sharing of resources with the second device if a match occurs between the transmitted vibration profile and the received vibration profile. Other embodiments are described and claimed.
