Abstract
SUAREZ CASTANON, Miguel S.; AGUILAR IBANEZ, Carlos and MARTINEZ GARCIA, Juan C.. A Simple Deterministic Lorenz Chaotic-Based Methodology to Cipher and Decipher Information. Comp. y Sist. [online]. 2007, vol.11, n.1, pp.26-38. ISSN 2007-9737.
We present a secure deterministic cipher and decipher mechanism based on the well-known Lorenz dynamic system. The ciphering process is performed by the combination of the message to be ciphered and the states of the Lorenz dynamic system, which act as the ciphering key. The deciphering process is implemented by the reconstruction of the key, which is generated using a Lorenz system state observer. The observed key is then used in the decipher process in order to recover the ciphered message.
