Journal ArticleDOI
Error Function Attack of chaos synchronization based encryption schemes
TL;DR: In this article, the authors define a quantitative measure (Quality Factor) of the effective applicability of a chaos encryption scheme, which takes into account the security, the encryption speed, and the robustness against channel noise.
Journal ArticleDOI
Decoding information by following parameter modulation with parameter adaptive control.
Changsong Zhou,Choy Heng Lai +1 more
TL;DR: In this paper, the authors considered the use of parameter adaptive control techniques to extract the message, based on the assumptions that we know the equation form of the chaotic system in the transmitter but do not have access to the precise values of the parameters which are kept secret as a secure set.
Journal ArticleDOI
Effects of a squeezed-vacuum reservoir on geometric phase
TL;DR: In this article, the geometric phase for a two-level atom in an electromagnetic field interacting with a squeezed-vacuum reservoir is calculated by establishing connecting density matrices, describing an evolution of a quantum open system, with a nonunit vector ray in a complex projective Hilbert space.
Journal ArticleDOI
On the synchronization of different chaotic oscillators
Gong Xiaofeng,Choy Heng Lai +1 more
TL;DR: The synchronization of two different chaotic oscillators is studied, based on an open-loop control – the entrainment control, and a hierarchical idea to synchronize multiple chaotic subsystems is proposed.
Journal ArticleDOI
Geometric phase in open two-level system
TL;DR: In this article, the geometric phase of the open two-level system depends only on the smooth (open or closed) curve in the complex projective Hilbert space of ray, which is formulated entirely in terms of geometric structures on this space.
