Analytic results and conclusion: The throughput of a slotted CSMA is well known to be better than that of unslotted case. C, is always worse than C , because the previous ICMA protocol' is similar to the unslotted CSMA as the ratio of b/a becomes smaller. Both C, and C, of the ICMA scheme will be inferior by 0.368 to the slotted ALOHA, when b / a becomes larger than 6 for C, and 8 for C,, as sh...
متن کاملCryptographic requirements for chaotic secure communications
In recent years, a great amount of secure communications systems based on chaotic synchronization have been published. Most of the proposed schemes fail to explain a number of features of fundamental importance to all cryptosystems, such as implementation details, or key definition, characterization, and generation. As a consequence, the proposed ciphers are difficult to realize in practice wit...
متن کاملPhase synchronization of chaotic intermittent oscillations.
We study phase synchronization effects of chaotic oscillators with a type-I intermittency behavior. The external and mutual locking of the average length of the laminar stage for coupled discrete and continuous in time systems is shown and the mechanism of this synchronization is explained. We demonstrate that this phenomenon can be described by using results of the parametric resonance theory ...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولTime Scaling of Chaotic Systems: Application to Secure Communications
The paper deals with time-scaling transformations of dynamical systems. Such scaling functions operate a change of coordinates on the time axis of the system trajectories preserving its phase portrait. Exploiting this property, a chaos encryption technique to transmit a binary signal through an analog channel is proposed. The scheme is based on a suitable time-scaling function which plays the r...
