SocIoTy is a practical cryptography mechanism which leverages a user’s existing smart-home devices to add a context-sensitive layer of security. SocIoTy treats the smart home as a pseudorandom function that users can query to provide at-home cryptographic services. When the user is physically at home, they can generate pseudorandom function outputs, and use these outputs to address their real-world needs—like generation of one-time passwords for authentication and of keys for cloud-encrypted content.
Unlike existing privacy-enhancing systems, SocIoTy protects against common surveillance techniques even if the user’s devices are compromised (like during border searches). It ties cryptographic operations to the home using existing smart-home devices.
