Abstract

Content is securely shared between communication devices in an ad-hoc manner by employing common sensing context to establish pairing between the communication devices. In one aspect, the communication devices are within a specified distance from each other and sense common signals from their environment over a specified time period. The common signals are analyzed to determine an initialization or session key, which is utilized to secure content transfer between the communication devices. Additionally or alternatively, the key is utilized to provide access to virtual (e.g., digital content) and/or physical (e.g., buildings) resources.
