<p>Logic locking is an efficient defense against attacks to the intellectual property of integrated circuits. However, in recent years, boolean satisfaction based attack (SAT attack) and a structural based attack named Valkyrie were proposed. As far as we know, most of the locking methods failed to achieve security for both of them and keep an acceptable overhead. In this paper, we present a self-adaptive striped-function logic locking method named SFLL-AD, based on repeatedly modifying the structure of the encryption block to a form that: (1) permits splitting and dispersing the encryption block across the netlist to have resilience to Valkryie (2) and guarantees not losing SAT resilience. Experimental results of our mehtod confirm the security to both attacks and show a small overhead (about 10% on average).</p>
