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.

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 ...

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.

PudgyTurtle Mode Resists Bit-Flipping Attacks

Cryptography, 2023
Cryptosystems employing a synchronous binary-additive stream cipher are susceptible to a generic attack called ’bit-flipping’, in which the ciphertext is modified to decrypt into a fraudulent message.

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 ...

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.

QUAD: Overview and Recent Developments [PDF]

, 2007
We give an outline of the specification and provable security features of the QUAD stream cipher proposed at Eurocrypt 2006. The cipher relies on the iteration of a multivariate system of quadratic equations over a finite field, typically GF(2) or a ...

Network topology drives population temporal variability in experimental habitat networks

Population Ecology, EarlyView.
Habitat patches connected by dispersal pathways form habitat networks. We explored how network topology affects population outcomes in laboratory experiments using a model species (Daphnia carinata). Central habitat nodes in complex lattice networks exhibited lower temporal variability in population sizes, suggesting they support more stable ...

A Novel Hybrid Elementary Cellular Automata and Its Application in a Stream Cipher

Applied Sciences
The 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.
