Abstract

An adaptive observer design technique proposed for nonlinear systems has been successfully applied to the Lorenz chaotic system which is used in cryptosystems. This observer does not use direct feedback but the adaptation scheme uses the feedback. One of the system parameters is assumed to be unknown and only one of the state variables, which is transmitted in the communication system, is assumed to be accessible. It is possible to transmit two different information signals over the same chaotic signal securely using this adaptive observer.

Özet

Doğrusal olmayan sistemler için önerilmiş bir adaptif gözleyici tasarım tekniği, kripto sistemlerinde kullanılan Lorenz kaotik sistemine başarıyla uygulanmıştır. Bu gözleyici doğrudan doğruya geribesleme kullanmaz; geribeslemeyi sadece adaptasyon algoritması kullanır. Sistem parametrelerinden bir tanesinin bilinmediği ve durum değişkenlerinden sadece birinin erişilebilir olduğu kabul edilmiştir. Haberleşme sisteminde karşı tarafa bu değişken gönderilmektedir. Bu adaptif gözleyici kullanılarak, iki ayrı bilgi sinyalinin aynı kaotik sinyal üzerinden güvenli bir şekilde gönderilmesi mümkündür.
