A White-Box Cryptographic Implementation for Protecting against Power Analysis
نویسنده
چکیده
Encoded lookup tables used in white-box cryptography are known to be vulnerable to power analysis due to the imbalanced encoding. This means that the countermeasures against white-box attacks can not even defend against gray-box attacks. For this reason, those who want to defend against power analysis through the white-box cryptographic implementation need to find other ways. In this paper, we propose a method to defend power analysis without resolving the problematic encoding problem. Compared with the existing white-box cryptography techniques, the proposed method has twice the size of the lookup table and nearly the same amount of computation. key words: white-box cryptography, power analysis, countermeasure

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 ...
متن کاملA Masked White-box Cryptographic Implementation for Protecting against Differential Computation Analysis
Recently, gray-box attacks on white-box cryptographic implementations have succeeded. These attacks are more efficient than white-box attacks because they can be performed without detailed knowledge of the target implementation. The success of the gray-box attack is reportedly due to the unbalanced encoding used to generate the whitebox lookup table. In this paper, we propose a method to protec...
متن کاملDifferential Power Analysis: A Serious Threat to FPGA Security
Differential Power Analysis (DPA) implies measuring the supply current of a cipher-circuit in an attempt to uncover part of a cipher key. Cryptographic security gets compromised if the current waveforms obtained correlate with those from a hypothetical power model of the circuit. As FPGAs are becoming integral parts of embedded systems and increasingly popular for cryptographic applications and...

متن کاملA New Digital Rights Management Solution Based on White-Box Cryptography
Digital rights management is an important technique to protect digital contents from abuse. Usually it is confronted with severe challenges because of the untrusted environment its application executed in. This condition is formally described as white-box attack model. White-box cryptography aims at protecting software implementation of cryptographic algorithms from white-box attack, hence can ...
