Low-Cost Countermeasure against RPA

On smart-cards, Elliptic Curve Cryptosystems (ECC) can be vulnerable to Side Channel Attacks such as the Re ned Power Analysis (RPA). This attack takes advantage of the apparition of special points of the form (0, y). In this paper, we propose a new countermeasure based on co-Z formulæ and an extension of the curve isomorphism countermeasure. It permits to transform the base point P = (x, y) in...

Countermeasure for collusion attacks against digital watermarking

Customer identification watermarking today is one of the most promising application domains of digital watermarking. It enables to identify individual copies of otherwise indistinguishable digital copies. If done without any precautions, those individual watermarking are vulnerable to a number of specialized attacks based on an attacker collecting more than one individual copy. Fingerprinting a...

Leakage Squeezing Countermeasure against High-Order Attacks

In the recent years, side channel attacks have been widely investigated. In particular, second order attacks (2O-attacks) have been improved and successfully applied to break many masked implementations. In this context we propose a new concept to hinder attacks of all order: instead of injecting more entropy, we make the most of a single-mask entropy. With specially crafted bijections instanti...

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 ...
