Low power techniques in a FPGA implementation of the hash function called Luffa are presented in this paper. This hash function is under consideration for adoption as standard. Two major gate level techniques are introduced in order to reduce the power consumption, namely the pipeline technique (with some variants) and the use of embedded RAM blocks instead of general purpose logic elements. Power...
This paper presents hardware implementations of a DES cryptoprocessor with masking countermeasures and their evaluation against side-channel attacks (SCAs) in FPGAs. The masking protection has been mainly studied from a theoretical viewpoint without any thorough test in a noisy real world designs. In this study the masking countermeasure is tested with first-order and higher-order SCAs on a fully-fledged...
In this paper, we propose the system reducing the power consumption based on the energy-aware control elements (ECE). ECE refers to the minimum unit module providing a service within the single system. For example, the home gateway system provides the visitor identification service. If it is the case, the main processor, the Ethernet module, the MPEG encoding module built-in camera, and etc. are needed...
The increased flexibility offered by FPGAs implies that more transistors are needed which leads to higher power consumption per logic gate. FPGAs power consumption is fast becoming an essential design consideration especially for mobile systems with a limited power supply. The effect of components' region-constrained placement on reducing internal nets total capacitance and the corresponding change...
