Abstract

NUNEZ-PEREZ, R.F. Current sources reduce to one channel the bidirectional chaotic encryption communication. Ing. invest. y tecnol. [online]. 2017, vol.18, n.4, pp.353-368. ISSN 2594-0732.

Intends to show that a procedure based on current sources, can reduce the number of channels in an encryptor/decryptor bidirectional, performed with a pair of identical circuits of Chua and synchronized according to Carroll and Pecora, and therefore be cost-effective and reliable. Simulates the circuit with the Workbench program and is built and evaluated its operation with some evidence of concealment and retrieving messages from reference and independent. Given that their results were acceptable and met the main characteristics that must respect a circuit of this type, according to the specialized bibliography, the proposed encryptor/decryptor, with minimal effort, can be transformed for use with circuits of Lorenz, Chen, Rössler, among others, at a new scheme of multiple channels. This value even more the profitability of the same. Also, it sees its application in the field of low frequency digital communications, specifically in the bidirectional sent binary messages through parametric modulation.
