Algebraic break of image ciphers based on discretized chaotic map lattices
(Elsevier Science Inc, 2011-01-01)
In this paper, we provide an algebraic cryptanalysis of a recently proposed chaotic image cipher. We show that the secret parameters of the algorithm can be revealed using chosen-plaintext attacks. Our attack uses the orbit ...
Breaking an orbit-based symmetric cryptosystem
(Pergamon-Elsevier Science Ltd, 2011-09)
We report a break for a recently proposed class of cryptosystems. The cryptosystem uses constant points of a periodic secret orbit to encrypt the plaintext. In order to break the system, it suffices to sort the constant ...
Cryptanalysis of a multi-chaotic systems based image cryptosystem
(Elsevier Science BV, 2010-01-15)
This paper is a cryptanalysis of a recently proposed multi-chaotic systems based image cryptosystem. The cryptosystem is composed of two shuffling stages parameterized by chaotically generated sequences. We propose and ...
Cryptanalysis of a new substitution-diffusion based image cipher
(Elsevier Science BV, 2010-07)
This paper introduces two different types of attacks on a recently proposed cryptosystem based on chaotic standard and logistic maps. In the two attacks, only a pair of (plaintext/ciphertext) was needed to totally break ...
Cryptanalysis of Fridrich's chaotic image encryption
(World Scientific Publishing, 2010-05)
We cryptanalyze Fridrich's chaotic image encryption algorithm. We show that the algebraic weaknesses of the algorithm make it vulnerable against chosen-ciphertext attacks. We propose an attack that reveals the secret ...
Kaotik kriptografinin çilesi
(IEEE, 2013-06-13)
Son yirmi yıldır araştırılan bir konu olmasına rağmen, kaotik kriptografi ana akım kriptografi literatüründe yer almıyor. Bu makalede, bu ayrımın nedenleri üzerinde durulmuştur.
Constructing a Turkish constituency parse treeBank
(Springer Verlag, 2016)
In this paper, we describe our initial efforts for creating a Turkish constituency parse treebank by utilizing the English Penn Treebank. We employ a semiautomated approach for annotation. In our previouswork [18], the ...
Chunking in Turkish with conditional random fields
(Springer-Verlag, 2015-04-14)
In this paper, we report our work on chunking in Turkish. We used the data that we generated by manually translating a subset of the Penn Treebank. We exploited the already available tags in the trees to automatically ...
Constructing a WordNet for Turkish using manual and automatic annotation
(Assoc Computing Machinery, 2018-05)
In this article, we summarize the methodology and the results of our 2-year-long efforts to construct a comprehensive WordNet for Turkish. In our approach, we mine a dictionary for synonym candidate pairs and manually mark ...
MorAz: An open-source morphological analyzer for Azerbaijani Turkish
(Association for Computational Linguistics (ACL), 2018)
MorAz is an open-source morphological analyzer for Azerbaijani Turkish. The analyzer is available through both as a website for interactive exploration and as a RESTful web service for integration into a natural language ...
