Algebraic Attacks on RFID Protocols [PDF]
, 2009 This work aims to identify the algebraic problems which enable many attacks on RFID protocols. Toward this goal, three emerging types of attacks on RFID protocols, concerning authentication, untraceability, and secrecy are discussed. We demonstrate the types of attacks by exhibiting previously unpublished vulnerabilities in several protocols and ...

Algebraic Attacks Galore! [PDF]
Groups – Complexity – Cryptology, 2009 Summary: This is the first in a two-part survey of current techniques in algebraic cryptanalysis. After introducing the basic setup of algebraic attacks and discussing several attack scenarios for symmetric cryptosystems, public key cryptosystems, and stream ciphers, we discuss a number of individual methods. The XL, XSL, and MutantXL attacks are based

Algebraic Attacks on Combiners with Memory [PDF]
, 2003 Recently, algebraic attacks were proposed to attack several cryptosystems, e.g. AES, LILI-128 and Toyocrypt. This paper extends the use of algebraic attacks to combiners with memory. A (k,l)-combiner consists of k parallel linear feedback shift registers (LFSRs), and the nonlinear filtering is done via a finite automaton with k input bits and l memory ...

Efficient Computation of Algebraic Immunity for Algebraic and Fast Algebraic Attacks [PDF]
, 2006 In this paper we propose several efficient algorithms for assessing the resistance of Boolean functions against algebraic and fast algebraic attacks when implemented in LFSR-based stream ciphers. An algorithm is described which permits to compute the algebraic immunity d of a Boolean function with n variables in $\mathcal{O}(D^2)$ operations, for $D ...

Efficient Image Encryption Based on New Substitution Box Using DNA Coding and Bent Function
IEEE Access, 2022 This study contributes to creating an unbreakable S-Box based on a strong bent function expanded by DNA sequences and investigates and analyzes the strength of the proposed S-Box against major standard criteria and benchmarks, such as interpolation ...

Yoneda Hacking: The Algebra of Attacker Actions
ACM Transactions on Cyber-Physical Systems, 2022 Our work focuses on modeling the security of systems from their component-level designs. Towards this goal, we develop a categorical formalism to model attacker actions. Equipping the categorical formalism with algebras produces two interesting results for security modeling.

Algebraic Attacks on Summation Generators [PDF]
, 2004 We apply the algebraic attacks on stream ciphers with memories to the summation generator. For a summation generator that uses n LFSRs, an algebraic equation relating the key stream bits and LFSR output bits can be made to be of degree less than or equal to \(^{\lceil\log_2 n \rceil}\) using ⌈log2 n ⌉ + 1 consecutive key stream bits. This is much lower

Accuracy and applicability of periodontitis risk assessment tools: A critical appraisal
Periodontology 2000, EarlyView., 2023 Abstract Currently, periodontal risk assessment finds application at first visit (to identify individuals at high risk of either disease incidence, if still healthy, or disease progression, if already diseased) as well as at patient monitoring after active treatment and enrolment in a supportive periodontal care program.
