Secure identification under jamming attacks

Abstract

In next generation connectivity systems, relying on robust and low-latency information exchange, there exists communication tasks in which the Ahlswede/Dueck identification scheme is much more efficient than Shannon's transmission scheme. We concentrate on the arbitrarily varying wiretap channel (AVWC) modeling jamming attacks. We provide a coding scheme for secure identification and determine the secrecy capacity of the AVWC. Furthermore, we analyze important properties of this capacity function, e.g. continuity and super-additivity.
