“…The new Lozi alternate system with auto-coupling and ring-coupling [27] has been selected because it satisfies the above conditions. Moreover, the system has good randomness and high chaoticity [13]. It has passed successfully statistical and numerical tests such as auto-correlation; cross-correlation; uniform distribution; chaoticity where x ∈ R p , T p = [−1, 1] p by the map M p = T p → T p :…”

“…Therefore, observer design requires a particular approach to achieve synchronization. Moreover, the pioneering idea in that paper is to use the system (1) with parameter a that allows us to increase executing speed [13]. The modified Lozi system (15) uses parameter a to change system dynamics according to the binary bit of the message 0/1:…”

To cite this version:Oleg Garasym, Ina Taralova, René Lozi. Application of observer-based chaotic synchronization and identifiability to original CSK model for secure information transmission.Abstract: The modified Lozi system is analyzed as chaotic PRNG and synchronized via observers. The objective of the study is to investigate chaotic-based encryption method that preserves CSK model advantages, but improves the security level. The CSK model have been discussed to message encryption because it implies better resistance against noise, but there are many evidences of the model weaknesses. The investigation provides the original CSK model analyses of secure message transmission over the communication channel by examining identifiability and observability; switched regimes detection; sensitivity to initial conditions and session key; NIST tests of the encrypted signal; correlation between wrong decrypted messages; system ergodicity. The proposed model has a significant effect on the security level of the transmitted signal that successfully passed chaotic and randomness tests. The results suggest that the original CSK model can be used for information security applications.

“…Recently, some published works on chaosbased block ciphers are very efficient in terms of security and computing time [4][5] [6] [7]. Also, some interesting works on lightweight stream ciphers are recently published [8] [9] [10] [11]. Stream ciphers are potential candidates for data encryption, along with block ciphers.…”

In this paper, we propose a novel stream cipher based on a chaotic system. In order to get the cipher text, the plain text is simply XORed with the key-stream generated by a strong pseudo chaotic number generator (PCNG). Then, all the security of the system is based on the used PCNG. The structure of the proposed PCNG includes two chaotic maps which are weakly coupled by a predefined matrix and integrates a swap function. The PCNG passes all statistical NIST's randomness tests. Also, analysis and experimental results show that the proposed stream cipher has a large key space, a high key sensitivity, and can resist against chosen-plaintext attack and chosen-ciphertext attack. Indeed, for each new execution of the system using the same secret key, the generated keysteram is different due to the IV-setup function. The computing performance of the proposed system is comparable to the main algorithms of eStream such as Rabbit and HC-128.
