Obviating Multiple Attacks with Enhanced Logic Locking
Pages 162 - 167
Abstract
With advancements in technology, attackers try to develop new threat models utilizing the loopholes in the security design techniques. Logical locking protects the design by the use of additional key inputs that makes the IC functional on the application of the correct key combination. SFLL is a popular logic locking method which is resilient to attacks like SAT attacks and brute force attacks. Introducing encrypt FF in sequential circuits make them resistant to logic cone based attacks and key sensitization attacks. In this paper a new technique which uses the underlying principles of encrypt FF as well as SFLL is proposed. The design is aimed at obtaining high output corruption which is verified by using Hamming distance and Jaccard similarity. Experimental results on ISCAS’89 benchmark circuits show that the improvement in security comes at the expense of design overheads.
