Abstract

Systems and methods for establishing secure communication between electronic devices. In some aspects, at least two computing devices physically interact with each other multiple times, and sensors in each device detect and record the times of the physical interactions. The times of the physical interactions are used as time secrets, which are used as a basis for generating a cryptographically secure key used as a shared secret among the devices to provide secure communications therebetween.
