Research on side-channel attacks has recently made a lot of progress, and one of the most potential solutions is a power analysis attack. Thus, focusing on countermeasures to improve the security level of cryptographic devices is a matter of concern. ...

Field Programmable Gate Arrays (FPGAs) are increasingly ubiquitous. FPGAs enable hardware acceleration and reconfigurability. Any security breach or attack on critical computations occurring on an FPGA can lead to devastating consequences. Side-channel ...

Side channel analysis attacks employ the emanated side channel information to deduce the secret keys from cryptographic implementations by analyzing the power traces during execution or scrutinizing faulty outputs. To be effective, a countermeasure must ...

Recent works have demonstrated the possibility of extracting secrets from a cryptographic core running on an FPGA by means of remote power analysis attacks. To mount these attacks, an adversary implements a voltage fluctuation sensor in the FPGA logic, ...

Blinding has been one of the most effective approaches to resist power analysis attacks on asymmetric cryptosystems like RSA. Blinding is similar to masking in symmetric cryptosystems, but masking can be implemented in various ways like Boolean, affine, ...

Template attack is the most powerful side-channel attack from an information theoretic point of view. This attack is launched in two phases. In the first phase (training) the attacker uses a training device to estimate leakage models for targeted ...

This study presents an approach to compute randomised modular exponentiation through non‐uniform exponent partitioning. The exponent has been first partitioned into multiple parts and then shuffled by Fisher Yates method. Thereafter, every partition ...

FPGA devices are increasingly deployed in wireless and heterogeneous networks in-field due to their re-programmable nature and high performance. Modern FPGA devices can have part of their logic partially reconfigured during runtime operation, which we ...

Power based side-channel attacks attempt to obtain the secret key from implementations of cryptographic algorithms, such as Advanced Encryption Standard (AES), by analyzing the power traces during execution. Such attacks employ statistical methods to ...

Modern embedded systems manage sensitive data increasingly often through cryptographic primitives. In this context, side-channel attacks, such as power analysis, represent a concrete threat, regardless of the mathematical strength of a cipher. ...

Side Channel Attacks are a major concern in modern security. Two main countermeasure techniques have been studied in order to counteract them: hiding and masking. Hiding techniques try to randomize the obtained traces by adding noise or by swapping ...

This article proposes a novel approach to cryptosystem design to prevent power analysis attacks. Such attacks infer program behavior by continuously monitoring the power supply current going into the processor core. They form an important class of ...

In cryptography, side channel attacks, such as power analysis, attempt to uncover secret information from the physical implementation of cryptosystems rather than exploiting weaknesses in the cryptographic algorithms themselves. The design and ...

Recently, there has been extensive research on mobile devices and stream cipher to increase security. The Rabbit stream cipher was selected for the final eSTREAM portfolio organized by EU ECRYPT and as one of algorithms of the ISO/IEC 18033-4 Stream ...

One of the biggest challenges of designers of cryptographic devices is to protect the devices against implementation attacks. Power analysis attacks are among the strongest of these attacks. This article provides an overview of power analysis attacks ...
