In this paper, low-cost and high-throughput hardware implementations of the HIGHT and
PRESENT lightweight block ciphers are presented. One of the most complex blocks in the …

Many FPGA computations, including block ciphers, require repetitive loop operations that
are difficult to parallelize. Sequential loop implementation leads to significant clock power …

Energy consumption of block ciphers is critical in resource constrained devices. Unrolling
has been explored in literature as a technique to increase efficiency by eliminating energy …

Portable devices, like mobile phones, are in an increasing need for power due to the
growing complexity of applications and services provided by them. At the same time, mobile …

In this paper, we present a glitch-less hardware structure based on a glitch filter for the
implementation of the block ciphers. The glitch filter circuit is used to build a glitch-free …

Abstract Field Programmable Gate Arrays (FPGAs) are becoming an ever more prominent
platform for the implementation of digital systems. In contrast to traditional processors that …

Field-programmable gate arrays (FPGAs) are used for a wide variety of computations in low-
cost embedded systems. Although these systems often have modest performance …
