Rights Management with NFC Smartphones and Electronic ID Cards: A Proof of Concept for Modern Car Sharing
TL;DR: This paper proposes a scheme that securely identifies a customer on a website and creates a (personalized) credential containing the booked access permissions that is safely transported via the Internet to the user’s smartphone and finally grants access to an NFC-enabled object.

Efficient Implementation of Galois Field Fixed Field Constant Multiplication
A.J. Elbirt,Christof Paar +1 more
TL;DR: A hardware architecture is presented that achieves efficient implementation of generalized Galois field fixed field constant multiplication, a core operation of Rijndael, chosen by the National Institute of Standards and Technology (NIST) as the advanced encryption standard (AES) advanced encryption algorithm in October of 2000.

SAT-based reverse engineering of gate-level schematics using fault injection and probing
TL;DR: In this paper, the authors show that an attacker who doesn't know gate functions or connections of an aggressively camouflaged circuit cannot learn the correct gate-level schematic even if able to control inputs and probe all combinational nodes of the circuit.
Proceedings ArticleDOI
Area efficient GF(p) architectures for GF(p/sup m/) multipliers
TL;DR: This contribution describes new GF(p) multipliers, for p>2, specially suited for GF( p/sup m/) multiplication, and constructs truth tables whose inputs are the bits of the multiplicand and multiplier and whose output is the bits that represent the modular product.
