Antitamper Conductive Mesh Used for Securing Cryptographic Modules
Daniel-Ciprian Vasile, Paul Mugur Svasta · 2018
Physical unique identity patterns, provided by the electronic components and electric circuits, are used in cryptographic applications in many forms. These patterns can act as secret data or cryptographic keys, rather than embodying them in non-volatile memories. This paper proposes a special antitamper conductive mesh that provides a unique identity pattern that can be used as cryptographic key. This key needs no energy for storage and is automatically compromised in case of tampering. In this way, the antitamper conductive mesh has dual role: physical antitamper structure and secret key. The proposed mesh can protect cryptographic modules, communication terminals, security and IoT devices.
