An Improved Algorithm of Key Stream Extraction with Slide Attack Resistant [PDF]

Jisuanji gongcheng, 2018
In order to enhance the ability of the stream cipher algorithm for Leak Extraction(LEX) in resisting slide attack,16 bytes from the intermediate variable are extracted at each key expansion of Advanced Encryption Standard(AES),and they are used as the ...

Cryptanalysis of a family of self-synchronizing chaotic stream ciphers [PDF]

, 2009
Unimodal maps have been broadly used as a base of new encryption strategies. Recently, a stream cipher has been proposed in the literature, whose keystream is basically a symbolic sequence of the (one-parameter) logistic map or of the tent map.

Functional Materials for Environmental Energy Harvesting in Smart Agriculture via Triboelectric Nanogenerators

Advanced Functional Materials, EarlyView.
This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...

Complex Cryptographic and User‐Centric Physically Unclonable Functions Enabled by Strain‐Sensitive Nanocrystals via Selective Ligand Exchange

Advanced Functional Materials, EarlyView.
This study investigates electromechanical PUFs that improve on traditional electric PUFs. The electron transport materials are coated randomly through selective ligand exchange. It produces multiple keys and a key with motion dependent on percolation and strain, and approaches almost ideal inter‐ and intra‐hamming distances.

Key-Dependent Feedback Configuration Matrix of Primitive σ–LFSR and Resistance to Some Known Plaintext Attacks

IEEE Access, 2022
In this paper, we propose and evaluate a method for generating key-dependent feedback configurations (KDFC) for $\sigma $ -LFSRs. $\sigma $ -LFSRs with such configurations can be applied to any stream cipher that uses a word-based LFSR.
