Researchers have devised a novel attack that recovers the secret encryption keys stored in smart cards and smartphones by using cameras in iPhones or commercial surveillance systems to video record.Power analysis is a type of side-channel attack, where the instantaneous power consumption of a device can be used to compromise the secret it holds. This is possible since the consumption of a device depends on the data and operations that are being processed.
The attack reveals the secret key of AES software implementations on smart cards by exploiting the fact that the power consumption of most smart-card processors leaks information during the AES key expansion.A major breakthrough in side channel attacks came up when analysis of power consumption by a cryptographic device led to discovery of the secret key. This analysis technique popularly known as Power Analysis Attack is now one of the most volatile and successful side channel attacks.
Power Analysis for Smartcard's Authentication
In this article we describe an efficient AES software imple-mentation that is well suited for 8-bit smart cards and resistant against power analysis attacks. Our implementation masks the intermediate sults and randomizes the sequence of operations at the beginning and end of the AES execution. This is measured the power consumption of the smart card with an oscilloscope. The acquired information can be analysed to determine information on what is occurring within a secure microprocessor.Well-equipped electronics labs have equipment that can digitally sample voltage differences at extraordinarily high rates (over 1GHz) with excellent ac-curacy.[1] A figure showing the traces of a smart card’s power consumption is illustrated below. Figure .
This paper examines how monitoring power consumption signals might breach smart-card security, and develops an approach to model the signal-to-noise ratio (SNR) and shows how this SNR can be significantly improved using a multiple-bit attack.
