In this work the problem of designing a secure communication system is addressed. Discrete time chaotic signals are used to mask information samples. Dead-beat synchronizing systems permit exact synchronization in finite time. This property can be used in secure communication schemes. An alternative approach uses a combination of chaotic signals to modulate the information to be masked. The sensitivity of the schemes to the key variation is analyzed and some communication issues are also discussed.

Abstract
In this work the problem of designing a secure communication system is addressed. Discrete time chaotic signals are used to mask information samples. Dead-beat synchronizing systems permit exact synchronization in finite time. This property can be used in secure communication schemes. An alternative approach uses a combination of chaotic signals to modulate the information to be masked. The sensitivity of the schemes to the key variation is analyzed and some communication issues are also discussed.
