كرست هذه المقالة من أجل تحليل تأثير التقنيات المعتمدة على الفوضى على مشفرات الكتلة. حيث سنستعرض العديد من المشفرات التي تعتمد على الفوضى. باستخدام المبادئ الأساسية المعروفة في التشفير نجد أن سلوك هذه المشفرات ليس أسوأ من المشفرات النموذجية المعروفة , و المقاربة الجديدة في هذه المقالة هي تصميم مشفرات كتلية.
This paper is devoted to the analysis of the impact of chaos-based
techniques on block encryption ciphers. We present several chaos
based ciphers. Using the well-known principles in the cryptanalysis
we show that these ciphers do not behave worse than the standard
ones, opening in this way a novel approach to the design of block
encryption ciphers.

In this paper, I study the motion of the double pendulum . I write
the Euler -Lagrange equations and canonical Hamilton's
equations. I study the special case in which one angle is constant,
where the double pendulum behaves as a simple pendulum.
This paper presents a new type of encryption, using a matrix

is an internal encryption.
As well as asymmetric encryption, where the ciphertext is inversely
