Power-analysis (PA) based side-channel attacks are effective methods to attack RSA encryption systems and elliptic-curve cryptography (ECC). In this paper, we describe PA-based side-channel attacks aiming to extract the (randomly chosen) private key for an ECC-based cryptosystem in detail. We assume that for the cryptosystem to be attacked the private key will not be available for more than one basic...
Elliptic curve cryptography (ECC) is widely used as an efficient mechanism to secure private data using public-key protocols. This paper focuses on ECC over prime fields (GF(p)). We present a novel hardware architecture that calculates the elliptic curve point multiplication (ECPM). Our processor supports arbitrary prime fields with sizes up to 1024 bits. Different standards, which use curves in short...
Bangap voltage references (BGRs) are widely used in today's circuits as references with a low temperature coefficient. Especially measurement circuits and metering applications demand a very low temperature coefficient to maintain the desired precision over the entire temperature range. Today's BGR designs use analog circuits to correct for the effects which lead to a temperature drift. In this paper...
