Differential fault analysis on PRINTcipher
IET Networks, 2013 The new block cipher PRINTcipher was introduced in CHES 2010 as a lightweight block cipher for ‘integrated circuit’ or IC‐‘printing’ technology. The key of PRINTcipher consist of two sub‐key components where the first sub‐key is ‘XORed’ to the state in ...

Improved Security Bound of (E/D)WCDM
IACR Transactions on Symmetric Cryptology, 2021 In CRYPTO’16, Cogliati and Seurin proposed a block cipher based nonce based MAC, called Encrypted Wegman-Carter with Davies-Meyer (EWCDM), that gives 2n/3 bit MAC security in the nonce respecting setting and n/2 bit security in the nonce misuse setting ...

Social context prevents heat hormetic effects against mutagens during fish development
FEBS Letters, EarlyView.This study shows that sublethal heat stress protects fish embryos against ultraviolet radiation, a concept known as ‘hormesis’. However, chemical stress transmission between fish embryos negates this protective effect. By providing evidence for the mechanistic molecular basis of heat stress hormesis and interindividual stress communication, this study ...

miRNA‐29 regulates epidermal and mesenchymal functions in skin repair
FEBS Letters, EarlyView.miRNA‐29 inhibits cell‐to‐cell and cell‐to‐matrix adhesion by silencing mRNA targets. Adhesion is controlled by complex interactions between many types of molecules coded by mRNAs. This is crucial for keeping together the layers of the skin and for regenerating the skin after wounding.

Proving chaotic behaviour of CBC mode of operation [PDF]
, 2015 International audienceThe cipher block chaining (CBC) block cipher mode of operation was invented by IBM (International Business Machine) in 1976. It presents a very popular way of encrypting which is used in various applications.

Deep Learning based Differential Distinguisher for Lightweight Block Ciphers [PDF]
arXiv, 2021 Recent years have seen an increasing involvement of Deep Learning in the cryptanalysis of various ciphers. The present study is inspired by past works on differential distinguishers, to develop a Deep Neural Network-based differential distinguisher for round reduced lightweight block ciphers PRESENT and Simeck.

FEBS Letters, EarlyView.We present the cellular transcription‐coupled Flp‐nick system allowing the introduction of a Top1‐mimicking cleavage complex (Flpcc) at a Flp recognition target site within a controllable LacZ gene. LacZ transcription leads to the collision of RNA polymerase II (RNAPII) with Flpcc, and this causes RNAPII stalling, ubiquitination, and degradation.

An Extension of Cook's Elastic Cipher [PDF]
arXiv, 2013 Given a block cipher of length L Cook's elastic cipher allows to encrypt messages of variable length from L to 2L. Given some conditions on the key schedule, Cook's elastic cipher is secure against any key recovery attack if the underlying block cipher is, and it achieves complete diffusion in at most q + 1 rounds if the underlying block cipher ...

FEBS Letters, EarlyView.Heart failure with preserved ejection fraction (HFpEF) accounts for half of the heart failure cases. It is characterised by microvascular dysfunction, associated with reduced pericyte coverage and diminished STAT3 expression in pericytes. Loss of STAT3 impairs pericyte adhesion, promotes senescence, and activates a pro‐fibrotic gene program.
