A Novel Color Image Encryption Scheme Using Rectangular Transform-Enhanced Chaotic Tent Maps
IEEE Access, 2017 In recent years, the chaos-based cryptographic algorithms have attracted a lot of attention. Specially, chaotic tent map (CTM)-based schemes show some good performances in randomness properties and security level.

Blockchain driven medical image encryption employing chaotic tent map in cloud computing
Scientific ReportsData security during transmission over public networks has become a key concern in an era of rapid digitization. Image data is especially vulnerable since it can be stored or transferred using public cloud services, making it open to illegal access ...

Chaotical PRNG based on composition of logistic and tent maps using deep-zoom [PDF]
Chaos, Solitons & Fractals, 2021 We proposed the deep zoom analysis of the composition of the logistic map and the tent map, which are well-known discrete unimodal chaotic maps. The deep zoom technique transforms each point of a given chaotic orbit by removing its first k-digits after ...

Statistical stability for Barge-Martin attractors derived from tent maps [PDF]
Discrete and Continuous Dynamical Systems. Series A, 2018 Let $\{f_t\}_{t\in(1,2]}$ be the family of core tent maps of slopes $t$. The parameterized Barge-Martin construction yields a family of disk homeomorphisms $\Phi_t\colon D^2\to D^2$, having transitive global attractors $\Lambda_t$ on which $\Phi_t$ is ...

Improvement of Chacha20 Algorithm based on Tent and Chebyshev Chaotic Maps
Iraqi Journal of Science, 2021 Chacha 20 is a stream cypher that is used as lightweight on many CPUs that do not have dedicated AES instructions. As stated by Google, that is the reason why they use it on many devices, such as mobile devices, for authentication in TLS protocol. This

Allowed Patterns of Symmetric Tent Maps via Commuter Functions [PDF]
SIAM Journal on Discrete Mathematics, 2016 We introduce a new technique to study pattern avoidance in dynamical systems, namely the use of a commuter function between non-conjugate dynamical systems.

Itineraries for Inverse Limits of Tent Maps: a Backward View [PDF]
, 2017 Previously published admissibility conditions for an element of { 0 , 1 } Z to be the itinerary of a point of the inverse limit of a tent map are expressed in terms of forward orbits.

Investigation of the difference between Chaos Degree and Lyapunov exponent for asymmetric tent maps
JSIAM Letters, 2019 Lyapunov exponent is commonly used as a measure of chaos. Chaos Degree is propsed as another measure of chaos based on information theory. The advantage of Chaos Degree is that it is calculable from data.
