Physical Time-Varying Transfer Function as Generic Low-Overhead Power-SCA Countermeasure

Low Overhead DPA Countermeasure using ExCCel (Exploration of Complementary Cells)

—Differential Power Analysis (DPA) side-channel attacks pose serious threats for embedded system security. WDDL was proposed as a countermeasure that can be incorporated into a conventional ASIC design flow using standard cells. However, our spice simulations show that DPA attacks on WDDL still leak secret keys to adversaries despite the doubled area and energy overheads due to the use of compl...

Threshold Implementation as a Countermeasure against Power Analysis Attacks

One of the usual ways to find sensitive data or secret parameters of cryptographic devices is to use their physical leakages. Power analysis is one of the attacks which lay in such a model. In comparison with other types of side-channels, power analysis is so efficient and has a high success rate. So it is important to provide a countermeasure against it. Different types of countermeasures use ...

Time-Varying Monetary Policy Reaction Function: The Case of Iran

Low-Overhead Time-Triggered Group Membership

A group membership protocol is presented and proven correct for a synchronous time-triggered model of computation with processors in a ring that broadcast in turn. The protocol, derived from one used for critical control functions in automobiles, accepts a very restrictive fault model to achieve low overhead and requires only one bit of membership information piggybacked on regular broadcasts. ...

Randomized Addition-Subtraction Chains as a Countermeasure against Power Attacks

Power Analysis attacks on elliptic curve cryptosystems and various countermeasures against them, have been first discussed by Coron ([6]). All proposed countermeasures are based on the randomization or blinding of the inputparameters of the binary algorithm. We propose a countermeasure that randomizes the binary algorithm itself. Our algorithm needs approximately 9% more additions than the ordi...
