Distinguishing Attacks on Stream Ciphers Based on Arrays of Pseudo-random Words
In numerous modern stream ciphers, the internal state consists of a large array of pseudo-random words, and the output key-stream is a relatively simple function of the state. In [16], it was heuristically shown that in various cases this structure may lead to distinguishing attacks on the cipher. In this paper we further investigate this structural attack. We present a rigorous proof of the ma...
متن کاملSome Results on Distinguishing Attacks on Stream Ciphers
Stream ciphers are cryptographic primitives that are used to ensure the privacy of a message that is sent over a digital communication channel. In this thesis we will present new cryptanalytic results for several stream ciphers. The thesis provides a general introduction to cryptology, explains the basic concepts, gives an overview of various cryptographic primitives and discusses a number of d...
متن کاملOn the Applicability of Distinguishing Attacks Against Stream Ciphers
We demonstrate that the existence of distinguishing attacks against stream ciphers is unrelated to their security in practical use, and in particular that the amount of data required to perform a distinguishing attack is unrelated to the key length of the cipher. The implication for the NESSIE Project is that no submitted symmetric cipher would be accepted under the unpublished rules for distin...
متن کاملLinearisation Attacks on FCSR-based Stream Ciphers
This paper presents a new class of cryptanalytic attacks, which are applicable against those binary additive synchronous stream ciphers, whose analysis theory is based on the properties of 2-adic numbers. These attacks are named as ‘Linearisation Attacks’. Linearisation attacks consist of three variants, which are referred as ‘Conventional Linearisation Attacks (CLAs)’, ‘Fast Linearisation Atta...
متن کاملOn Data Complexity of Distinguishing Attacks vs. Message Recovery Attacks on Stream Ciphers
We revisit the different approaches used in the literature to estimate the data complexity of distinguishing attacks on stream ciphers and analyze their inter-relationships. In the process, we formally argue which approach is applicable (or not applicable) in what scenario. To our knowledge, this is the first kind of such an exposition. We also perform a rigorous statistical analysis of the mes...
