One Attack to Rule Them All: Collision Timing Attack versus 42 AES ASIC Cores
TL;DR: A collision timing attack which exploits the data-dependent timing characteristics of combinational circuits is demonstrated and is based on an also recently published correlation collision attack, which avoids the need for a hypothetical timing model for the underlying combinational circuit to recover the secret materials.
Book ChapterDOI
Lightweight cryptography and RFID: tackling the hidden overheads
TL;DR: This paper considers the case of CRYPTOGPS and outlines a full implementation that has been fabricated in ASIC, Interestingly, the implementation requirements still remain within the typically-cited limits for on-the-tag cryptography.
Book ChapterDOI
Hyperelliptic curve coprocessors on a FPGA
TL;DR: A comprehensive investigation of high-efficient HEC architectures by proposing a genus-2 hyperelliptic curve cryptographic coprocessor using affine coordinates and providing three different implementations ranging from high speed to moderate area.
Proceedings ArticleDOI
Toward an FPGA architecture optimized for public-key algorithms
A.J. Elbirt,Christof Paar +1 more
TL;DR: This contribution investigates existing FPGA architectures with respect to modular multiplication and proposes a new FPGAs architecture optimized for the wide-operand additions required for modular multiplication.
Journal ArticleDOI
Side channels as building blocks
Markus Kasper,Amir Moradi,Georg T. Becker,Oliver Mischke,Tim Güneysu,Christof Paar,Christof Paar,Wayne Burleson +7 more
TL;DR: The solutions summarized in this article provide general guidelines for theorists and practitioners to use side channels constructively to achieve designs that are robust against detection and removal.
