eLoBa Chaotic Keystream Cipher: Implementation, Analysis and Performance

Abstract

Many computer-based security services are required by modern society, such as cipher/decipher, authentication and integrity.Security services are implemented by cryptographic systems, such as symmetric (block and keystream) and asymmetric.We focus our attention to a special sort of keystream cryptographic systems, based on chaotic systems.In our paper, we describe eLoBa architecture, based on Lorenz chaotic system.We also analyze one important security issue of keystream cryptographic systems, the cycle length.Finally, we compare eLoBa against several cryptographic systems, for its performance on a authentication service implementation on a resource constraint smart-card.
