In this paper we investigate how different randomization approaches influence the success of horizontal DPA attacks. We use our own ECC design to run the experiments. We applied the following randomization techniques: EC point blinding, key randomization and a combination of both. Our experiments demonstrate the fact that these well-known randomizations of processed data are not effective against...
IR-UWB (Impulse Radio Ultra Wideband) is commonly used for RADAR applications. Since the UWB standard IEEE802.15.4a has been introduced in 2004, UWB is also used for communication. Even tho the standard IEEE802.15.4a allows also to perform ranging, no ranging method is mandated. Ranging devices based on IEEE802.15.4a usually exchange timing data in order to determine the distance between each other...
This paper describes a localization method for an IR-UWB (Impulse Radio Ultra Wideband) two-way ranging system developed for precise time-of-arrival measurements. The ranging system provides a time resolution of 275 ps, which allows precise indoor distance estimation with the accuracy of 4 cm. In this work, a two-way ranging algorithm has been extended into a localization algorithm without the need...
Using UWB for wireless short range, low rate communication is attracting growing interest due to its low power consumption and very high bandwidth. Regarding these qualities, it is comprehensible that there is an interest in the automation industry to use ultra-wideband-based wireless sensor nodes to replace wired systems, to save energy and to save costs without reducing the reliability of the whole...

This paper describes a monolithic integrated single-chip transceiver intended for impulse radio (IR) — Ultra-wide Band (UWB) applications compliant to the IEEE 802.15.4a standard. The transceiver operates in the higher UWB band on four different channels, which fit into the European spectral mask (defined by the ECC). In accordance to the standard, several data rates up to 27.24 MB/sec have been implemented...
A digital baseband was designed and implemented according to the standard IEEE802.15.4a both in FPGA and as well as ASIC. The baseband supports data rates 850 Kb/s, 6.81 Mb/s and 27.24 Mb/s running at the clock speed of 31.2 MHz. The transmitter and receiver were tested by introducing various distortions to the signal being received. The baseband was shown to be fully functional being able to receive...

This paper describes a monolithic integrated singlechip transceiver intended for impulse radio (IR) — Ultra-wide Band (UWB) applications compliant to the IEEE 802.15.4a standard. The transceiver operates in the higher UWB band on the mandatory channel #9 (7.9872 GHz). The implemented nominal data rate is 850 kb/sec. The presented chip consists of the entire RF-front-end, 6bit-resolution successive...
This paper presents a monolithically integrated ultra wideband direct up conversion transmitter designed in accordance with IEEE 802.15.4a standard. The transmitter operates in the higher UWB band in eight communication channels. It supports the burst position and the binary phase-shift keying modulation schemes and provides a modulated impulse sequence with a pulse repetition frequency up to 499...
Using UWB for wireless short range, low rate communication is attracting growing interest due to its low power consumption and very high bandwidth. Moreover, it is able to offer accurate localization in the range of few centimeters. Regarding these qualities, it is desirable to design an IR-UWB transceiver which consumes as little power as possible when it is applied for battery driven wireless sensors...

Using UWB for wireless short range, low rate communication has been attracting growing interest due to its low power consumption and very high bandwidth. Moreover, it is able to offer accurate localization in the range of few centimeters. Recognising these qualities, it is desirable to design IR-UWB transceiver which can draw minimum possible power when it is applied for battery driven wireless sensors...
