Cryptanalysis of Achterbahn [PDF]
, 2006 . We present several attacks against the Achterbahn stream cipher, which was proposed to the eSTREAM competition. We can break the reduced and the full version with complexity of 2 55 and 2 61 steps.

Stream Cipher Using Genetic Algorithm [PDF]
Al-Rafidain Journal of Computer Sciences and Mathematics, 2009 The research tackles newly suggested method in generating the random key used in stream cipher, by generating the key randomly using rand function and then applying randomness conditions if the produced key satisfy the conditions then its accepted key ...

Strike: Stream Cipher Based on Stochastic Lightning Strike Behaviour
Applied Sciences, 2023 There is an increasing need for secure and fast encryption algorithms to support applications and communication protocols, and business models. In this paper, we present an alternative stream cipher (Strike) inspired by the stochastic behaviour of ...

Quantum Noise Randomized Ciphers
, 2006 We review the notion of a classical random cipher and its advantages. We sharpen the usual description of random ciphers to a particular mathematical characterization suggested by the salient feature responsible for their increased security.

On the Key-Uncertainty of Quantum Ciphers and the Computational Security of One-way Quantum Transmission [PDF]
, 2004 We consider the scenario where Alice wants to send a secret (classical) $n$-bit message to Bob using a classical key, and where only one-way transmission from Alice to Bob is possible.

A Novel Hybrid Elementary Cellular Automata and Its Application in a Stream Cipher
Applied SciencesThe elementary cellular automata (ECAs) under the chaotic rule possess long periodicity and are widely used in pseudo-random number generators. However, their period is limited, related to the rule and the number of cells.

A New Type of Cipher: DICING_csb [PDF]
, 2007 In this paper, we will propose a new type of cipher named DICING_csb, which is derived from our previous stream cipher DICING. It has applied a stream of subkey and an encryption form of block ciphers, so it may be viewed as a combinative of stream ...

A Practical Attack on the MIFARE Classic [PDF]
, 2008 The MIFARE Classic is the most widely used contactless smart card in the market. Its design and implementation details are kept secret by its manufacturer.

FEBS Letters, EarlyView.Cells must clear mislocalized or faulty proteins from membranes to survive. The AAA+ ATPase Msp1 performs this task, but dissecting how its six subunits work together is challenging. We engineered linked dimers with varied numbers of functional subunits to reveal how Msp1 subunits cooperate and use energy to extract proteins from the lipid bilayer ...

Cryptanalysis of an MPEG-Video Encryption Scheme Based on Secret Huffman Tables [PDF]
, 2007 This paper studies the security of a recently-proposed MPEG-video encryption scheme based on secret Huffman tables. Our cryptanalysis shows that: 1) the key space of the encryption scheme is not sufficiently large against divide-and-conquer (DAC) attack ...
