The principle of random selection and the principle of adding biased noise are new paradigms used in several recent papers for constructing lightweight RFID authentication protocols. The cryptographic power of adding biased noise can be characterized by the hardness of the intensively studied Learning Parity with Noise (LPN) Problem. In analogy to this, we identify a corresponding learning problem for random selection and study its complexity. Given L secret linear functions $f_1,\ldots,f_L… 

Lightweight Cryptography on Ultra-Constrained RFID Devices

TLDR
This thesis presents LIZARD, a new lightweight stream cipher for ultra-constrained RFIDs, which combines the explicit use of packet mode with a new type of state initialization algorithm and is particularly suitable for passive RFID tags, which obtain their energy exclusively through an electromagnetic field radiated by the reading device.

Hardware Efficient Authentication based on Random Selection

TLDR
This work considers a leakage-resilient re-keying function and evaluates its security at different abstraction levels, and hopes that the design principles on which it is based will trigger the interest of symmetric cryptographers to design new block ciphers combining good properties for secure implementations and security against black box (mathematical) cryptanalysis.

Area efficient cryptographic ciphers for resource constrained devices

TLDR
This paper proposes lightweight cryptography for FPGAs by introducing block cipher independent optimization techniques for Altera Cyclone III FPGA and applying them to the lightweight cryptographic algorithms HIGHT and Present, which are less than half the size of the AES implementation without using block RAMs.

A Protocol for Provably Secure Authentication of a Tiny Entity to a High Performance Computing One

TLDR
It is shown that the proposed authentication protocol is secure against active attacking scenarios and so called GRS man-in-the-middle (MIM) attacking scenarios, and provides reduction of the implementation complexity and at least the same level of the cryptographic security.

AES S-box using Fermat's Little Theorem for the highly constrained embedded devices

TLDR
An optimization methodology that would efficiently reduces the code size of the S-box, the most expensive operation of the Advanced Encryption Standard (AES), is proposed using an inversion algorithm based on Fermat's Little Theorem.

Generic Construction of Audit Logging Schemes with Forward Privacy and Authenticity

TLDR
A generic audit logging scheme with forward privacy and authenticity is proposed, which consists of a symmetric encryption scheme and a MAC function and uses a forward-secure pseudorandom generator to achieve forward security.

TLDR
By making use of the user’s biometrical behavior while entering text into the smartphone, the approach transparently authenticate the user in an ongoing-fashion and is able to continuously authenticate some users with high precision.

More on the Security of Linear RFID Authentication Protocols

TLDR
Some evidence is obtained that the security of (n,k,L)-protocols can be reduced to the hardness of the learning unions of linear subspaces (LULS) problem and a learning algorithm for LULS based on solving overdefined systems of degree L in Ln variables is presented.

New Algorithms for Learning in Presence of Errors

TLDR
A slight (?) variation of the structured noise model, where upon pressing a button, the authors receive 10 random vectors a1, a2, ... , a10 ∈ GF(2)n, and corresponding bits b1, b2,..., b10, of which at most 3 are noisy, is introduced, and a polynomial-time algorithm to recover the secret vector u is exhibited.

TLDR
This paper proves a conjecture of [Levin 87, sec. 5.6.2] that the scalar product of Boolean vectors p, g, x is a hard-core of every one-way function ƒ, and extends to multiple (up to the logarithm of security) such bits and to any distribution on the <italic>x</italic>.
