Practical algebraic attacks on the Hitag2 stream cipher
, 2009 Hitag2 is a stream cipher that is widely used in RFID car locks in the automobile industry. It can be seen as a (much) more secure version of the [in]famous Crypto-1 cipher that is used in MiFare Classic RFID products. Recently, a specification of Hitag2

Metroeconomica, EarlyView.ABSTRACT The paper examines the financial balances of the US economy. Government is the main borrower and households and the foreign sector the main lenders. Business net lending is minimal. The balances and their underlying transactions contradict the loanable funds theory and its “global savings glut” variation.

Preimage and collision attacks on reduced Ascon using algebraic strategies
CybersecurityAscon, a family of algorithms that supports hashing and authenticated encryption, is the winner of the NIST Lightweight Cryptography Project. In this paper, we propose an improved preimage attack against 2-round Ascon-XOF-64 with a complexity of $$2^{33}$

Highly Nonlinear Boolean Functions with Optimal Algebraic Immunity and Good Behavior Against Fast Algebraic Attacks [PDF]
, 2011 In this paper, we present a new combinatorial conjecture about binary strings. Based on the new conjecture, two classes of Boolean functions of $2k$ variables with optimal algebraic immunity are proposed, where $k\ge 2$.

How to Match Cognitive Model Predictions With EEG Data
Topics in Cognitive Science, EarlyView.Abstract Reliably identifying relevant brain areas implicated by the simulated activity from cognitive models is still an unsolved problem for cognitive modeling, particularly when matching model output with human electroencephalography (EEG) data. We propose a new method involving postprocessing of ACT‐R module activity and clustered EEG component ...

Open problems related to algebraic attacks on stream ciphers
, 2005 . The recently developed algebraic attacks apply to all keystream generators whose internal state is updated by a linear transition function, including LFSR-based generators.

Algebraic Side-Channel Collision Attacks on AES [PDF]
, 2007 This paper presents a new powerful side-channel cryptanalytic method - algebraic collision attacks - representing an efficient class of power analysis being based on both the power consumption information leakage and specific structure of the attacked ...
