Rigid Fluorescent Indacenetetraone‐Based Semiconducting Polymers via Knoevenagel Condensation
Advanced Functional Materials, EarlyView.New donor–acceptor polymers prepared by Knoevenagel condensation of indacenedithiophene‐ and indacenedifuran‐based aldehydes reveal an exceptionally rigid backbone, which is manifested in the remarkably narrow absorption and emission bands in red to near‐infrared region.

Enhancing Security of Vigenere Cipher by Stream Cipher
International Journal of Computer Applications, 2014 Cryptography is a science of converting clear message into secret message "nonreadable message", where message was encrypted at sender side then decrypted at receiver side. Vigenere is an example of substitution cipher, it has various limitations, in this paper we propose an advanced encryption algorithm which improves the security of Vigenere method ...

Cell Membrane Vesicle Camouflaged Artificial Cells
Advanced Functional Materials, EarlyView.Artificial cells camouflaged with a cell membrane vesicle coating are able to assemble into synthetic aggregates that exhibit rudimentary communication capabilities. Additionally, when these artificial cells are equipped with antioxidant capabilities, they are able to protect the intracellular homeostasis in HepG2 cells present in semi‐synthetic ...

Multilevel Permutation with Different Block Size/ Stream Cipher Image Encryption [PDF]
Iraqi Journal for Electrical and Electronic Engineering, 2015 In this work, a new image encryption method using a combined multilevel permutation with stream cipher is proposed. In the permutation algorithm, image is divided into blocks in each level and its blocks are rearranged by using pseudorandom permutation

Spin‐Selective Anisotropic Magnetoresistance Driven by Chirality in DNA
Advanced Functional Materials, EarlyView.It is shown that magnetoresistance (MR) measurements carried out as a function of angular dependence between the magnetic field and a chiral (DNA) interface provide a valuable new insight into the charge transport mechanism associated with the chiral‐induced spin selectivity (CISS) effect.

Design of Quantum Stream Cipher: Part-I -Lifting the Shannon Impossibility Theorem- [PDF]
arXivThis paper is dedicated to the late Professor H.P. Yuen in commemoration to our 50-year friendship. He invented the concept of quantum stream cipher. It is designed based on a completely different concept from conventional ciphers. The purpose of this cipher is to provide information-theoretic security of long data and secret key with short key length.

New Family of Stream Ciphers as Physically Clone-Resistant VLSI-Structures [PDF]
arXiv, 2019 A new large class of $2^{100}$ possible stream ciphers as keystream generators KSGs, is presented. The sample cipher-structure-concept is based on randomly selecting a set of 16 maximum-period Nonlinear Feedback Shift Registers (NLFSRs). A non-linear combining function is merging the 16 selected sequences.
