This paper evaluates the security of the L-Band Digital Aviation Communication System (LDACS) using Physical Unclonable Functions (PUFs) for authentication, identifying vulnerabilities related to prediction, quantum computing, and aging, and proposes Public Key Infrastructure (PKI) as a robust alternative.

This paper demonstrates that Simple Power Analysis (SPA) can successfully extract secret session key bits from post-quantum cryptosystems, specifically during the key decapsulation phase, using only a small number of power traces.
