WHITENOISE SECURE CIRCUIT DESIGN IMPLEMENTATION TECHNIQUES TO PREVENT POWER ANALYSIS ATTACKS AND OTHER SIDE CHANNEL ATTACKS, SECURE OTHER PHYSICAL CRYPTOSYSTEM IMPLEMENTATIONS, AND IMPLEMENTATION OF WHITENOISE INTO LOW COST MICRO PROCESSING AND SMART COMPONENTS RETAINING ONE-TIME-PAD CHARACTERISTICS

摘要

Two circuit design techniques are examined which improve the robustness ofWhitenoise encryption algorithm implementation against side-channel attacksbased ondynamic and/or static power consumption. The first technique conceals thepower consumptionand has linear cost. The second technique randomizes the power consumption andhasquadratic cost. These techniques are not mutually exclusive; their synergyprovides a goodrobustness against power analysis attacks. Other circuit-level protection canbe applied on topof the proposed techniques, opening the avenue for generating very robustimplementations.
