Abstract

Secure communication between two paired electronic devices already in wireless communication is established by generating a cryptographic key based on environmental data measured independently in each of the devices via one or more sensors. A processed version of the data is exchanged securely between the devices using known techniques, and each device accesses local and remote representations of the environmental data to determine if it represents a shared experience, by comparing the local and remote representations. The local and remote representations of the data are then used independently in the two devices to generate a common cryptographic key. The environmental data may be obtained with microphones sensing the ambient sound field, cameras taking photographs of the same scene, sensing signal strength of radio frequency radiation, obtaining the users' biometric data, or moving the two devices together for example by shaking or colliding them.
