Physics meets Security: Anchor and connecting physical goods into the digital world
By uniquely combining physical-layer properties and applied cryptography, PHYSEC was able to create a novel technology for securing the Internet of Things (IoT). Compared to classical cryptography, the technology by hand represents a fundamentally differentiable paradigm that realizes security objectives by measuring the characteristics of the electromagnetic wave propagation and the use of the physical condition and environment of a device. Our Start-up PHYSEC uses this technology to create novel cryptographic and security applications, such as:
- Random number generator
- Remote identification/authentication of entities over insecure networks
- Highly secure, forgery-proof labels
- Online communication protocol, which verifies remotely over arbitrary distances that a tamper sensitive system has not been tamperd with, and which considerably saves upon storage requirements compared to existing protocols
- Post-quantum resistant physical key exchange
- Relay station attack prevention
- Tamper sensitive systems
- Remote check of hardware integrity
- Proofs of colocality of two interacting systems
- Virtual proof of reality to proof the physical integrity, authenticity and condition of an object cryptographically
Disordered electromagnetic systems
Practically every object differs from an identical object due to unique and unclonable production-dependent variations. The advantage of such structures (3D arrangements of meso- and macroscopic objects) is their higher random information content in comparison with ICs, since they are three-dimensional. By making these structures machine-readable, we can realize a variety of new applications.
Virtually every environment differs in time and space from other environments and introduces randomness to radio transceivers. Due to its physical properties, symmetry and spatial diversity, wireless channel parameters can be modelled as a bidirectional entropy source not shared with others.
