Security Issues in QCA Circuit Design - Power Analysis Attacks

摘要: Quantum-dot cellular automata (QCA) technology has advantages of fast computation performance, high density and low power consumption. Thus, it is believed that QCA attractive for designing future digital systems. Side channel attacks including analysis have become a significant threat to the security cryptographic circuits using CMOS technology. A attack can reveal secret key cipher by measuring consumption cipher’s hardware platform while encrypting or decrypting data. As extremely when compared their counterparts, may be possible build are immune Therefore, in this chapter an investigation into both best worst case scenarios attackers carried out ascertain if such advantage. more efficient design sub-module Serpent proposed previous design. By upper bound model, first circuit (Serpent sub-module) presented. The results show scenario attackers, would vulnerable attack. However, practical greatly improved applying smoother clock. Moreover, scenario, reversible with Bennett clocking could used as natural countermeasure niche implementation architectures resistant
