The Wiretap Channel for Capacitive PUF-Based Security Enclosures. (arXiv:2202.01508v1 [cs.CR])

In order to protect devices from physical manipulations, protective security
enclosures were developed. However, these battery-backed solutions come with a
reduced lifetime, and have to be actively and continuously monitored. In order
to overcome these drawbacks, batteryless capacitive enclosures based on
Physical Unclonable Functions (PUFs) have been developed that generate a
key-encryption-key (KEK) for decryption of the key chain. In order to reproduce
the PUF-key reliably and to compensate the effect of noise and environmental
influences, the key generation includes …
