ARMADILLO: A Multi-purpose Cryptographic Primitive Dedicated to Hardware

Serge Vaudenay, Stéphane Badel, Pouyan Sepehrdad, Nilay Dagtekin, Khaled Ouafi, Jorge Nakahara, Petr Susil

This paper describes and analyzes the security of a general-purpose cryptographic function design, with application in RFID tags and sensor networks. Based on these analyzes, we suggest minimum parameter values for the main components of this cryptographic ...

Springer2010

In this paper, the impact of the wire grid size on the power-delay-area trade off of VLSI digital circuits with differential routing is analyzed. To this aim, the differential MOS current-mode logic (MCML) is adopted as reference logic style, and a complet ...

MOS current-mode logic standard cells for high-speed low-noise applications

Stéphane Badel

With the continuous shrinking of devices dimensions in microelectronic circuits, it is becoming extremely desirable to integrate analog circuitry together with complex digital logic blocks. The noise generated by the digital parts in a mixed-signal integra ...

CMOS realization of two-dimensional mixed analog-digital Hamming distance discriminator circuits for real-time imaging applications

Alexandre Schmid, Yusuf Leblebici, Stéphane Badel

The architecture of an integrated Hamming artificial neural network, and its use as a versatile signal/image processing circuit is presented. The circuit operation relies oil the charge-based processing of sum-of-products terms, complemented with digital p ...

Tri-State Buffer/Bus Driver Circuits in MOS Current-Mode Logic

Yusuf Leblebici, Stéphane Badel

In this paper, two circuits are proposed to implement tri-state buffers/bus drivers for MOS Current-Mode Logic digital circuits. The first is a switch-based, fully differential circuit, while the second is a voltage follower-based, pseudodifferential circu ...

Early Wire Characterization for Predictable Network-on-Chip Global Interconnects

Giovanni De Micheli, David Atienza Alonso, Yusuf Leblebici, Srinivasan Murali, Stéphane Badel, Ilhan Hatirnaz

This work envisions a common design methodology, applicable for every interconnect level and based on early wire characterization, to provide a faster convergence to a feasible and robust design. We claim that such a novel design methodology is vital for u ...
