IACR Transactions on Symmetric CryptologyTime-memory-data tradeoff attacks, as described by Babbage (1995), Golić (1997), and Biryukov and Shamir (2001), require the internal state of a stream cipher to be at least twice the desired security level n, or equivalently twice the key length.

State convergence in the initialisation of the Sfinks stream cipher [PDF]
, 2012 Sfinks is a shift register based stream cipher designed for hardware implementation. The initialisation state update function is different from the state update function used for keystream generation.

Flexible Dielectric Acoustic Resonator Patch for Tissue Regeneration
Advanced Materials, EarlyView.A flexible dielectric acoustic resonator patch enables MHz‐range ultrasound generation through resonance amplification without using piezoelectric materials. Conformal integration on a curved substrate allows efficient acoustic delivery to tissue‐mimicking environments.

Advanced Materials, EarlyView.We introduce a molecular strategy to assemble one‐dimensional (1D) materials into two‐dimensional (2D) van der Waals metal–organic frameworks (MOFs). Crystals of [FeX(pzX)(bpy)] (X = Cl, F) form anisotropic 2D layers that can be mechanically exfoliated into thin sheets.

Numerical solvers and cryptanalysis
Journal of Mathematical Cryptology, 2009 In this paper, we present an approach to apply numerical methods in the cryptanalysis of modern cryptographic algorithms. We focus on the stream cipher Trivium. It is a stream cipher recommended by the eStream project in the hardware category.

Stream Ciphers Analysis Methods
International Journal of Computers Communications & Control, 2010 The purpose of this paper is to present and to discuss analysis methods applied in symmetric cryptography, especially on stream ciphers. The tests were made on some algorithms and also on the personal symmetric cryptographic algorithm, HENKOS, based on a pseudorandom number generator.

A new fast stream cipher: MAJE4 [PDF]
, 2005 A new fast stream cipher, MAJE4 is designed and developed with a variable key size of 128-bit or 256-bit. The randomness property of the stream cipher is analysed by using the statistical tests.

Strumok stream cipher: Specification and basic properties [PDF]
, 2017 STRUMOK is a word-oriented additive stream cipher, where a word in the specification is chosen to be 64 bits. STRUMOK cipher uses some basic design principles from the stream cipher SNOW 2.0.

Positively Charged Polymer‐Brush MOFs for Large‐Area, Pressure‐Resistant Gas Separation Membranes
Advanced Materials, EarlyView.A universal POPA strategy enables positively charged polymer‐brush MOFs with self‐adaptive interfacial interlocking to resist aggregation under fast processing. This design ensures seamless dispersion within large‐area selective layers, achieving 1 m‐wide roll‐to‐roll fabrication of pressure‐resistant MMCMs with tunable CO2 separation performance ...
