PROJECT TITLE :
Randomized Multitopology Logic Against Differential Power Analysis
ABSTRACT:
Side channel attacks became one amongst the most significant issues in trendy digital systems. In specific, differential power analysis (DPA) has emerged as a powerful technique as a result of it does not need any assumptions regarding the hardware implementation of a crypto-chip. In this paper, a brand new randomized multitopology logic (RMTL) is proposed to boost immunity to DPA. RMTL refers to a family of dedicated security-oriented gates whose power profile cannot be predicted by external observers. Specifically, each gate of this logic will be configured in real time to control in a very completely different circuit topology, where every topology induces a different power profile. Immunity to DPA attacks is obtained by randomly changing every gate’s topology on run time. The suggested approach will coexist with common existing countermeasures. Theoretical analysis and simulation results, conducted in an exceedingly commonplace 40-nm technology, clearly show higher immunity to DPA attacks when using the proposed approach compared with commonplace CMOS implementation.
