TLDR
The value of maximal Lyapunov exponent of the proposed chaotic map goes beyond 1 and shows more chaotic behaviour than existing one-dimensional chaotic maps, showing that proposed chaotic maps are more effective for cryptographic applications.Abstract:
In this article, we proposed a new chaotic map and is compared with existing chaotic maps such as Logistic map and Tent map. The value of maximal Lyapunov exponent of the proposed chaotic map goes beyond 1 and shows more chaotic behaviour than existing one-dimensional chaotic maps. This shows that proposed chaotic maps are more effective for cryptographic applications. Further, we are using one-dimensional chaotic maps to generate random time series data and define a method to create a network. Lyapunov exponent and entropy of the data are considered to measure the randomness or chaotic behaviour of the time series data. We study the relationship between concurrence (for the two-qubit quantum states) and Lyapunov exponent with respect to initial condition and parameter of the logistic map which is showing how chaos can lead to concurrence based on such Lyapunov exponents.read more

Simple proof of security of the BB84 quantum key distribution protocol
Peter W. Shor,John Preskill +1 more
TL;DR: It is proved that the 1984 protocol of Bennett and Brassard (BB84) for quantum key distribution is secure, and a key distribution protocol based on entanglement purification is given, which can be proven secure using methods from Lo and Chau's proof of security for a similar protocol.

Quantum cryptography without Bell's theorem.
TL;DR: A related but simpler EPR scheme is described and it is proved it secure against more general attacks, including substitution of a fake EPR source and the original 1984 key distribution scheme of Bennett and Brassard, which uses single particles instead of EPR pairs.

Cryptography with chaos
TL;DR: It is possible to encrypt a message using the ergodic property of the simple low-dimensional and chaotic logistic equation, in order to transfer the trajectory from an initial condition towards an ϵ-interval inside the logistic chaotic attractor.

Calculation of Lyapunov exponents for dynamic systems with discontinuities
TL;DR: In this paper, the spectrum of Lyapunov exponents for nonlinear dynamical systems with discontinuities was generalized to nonlinear systems with continuous exponents, where the required linearized equations have to be supplemented by transition conditions at the instants of discontinuity.
