Abstract: Most of the current economic software solutions are based on distributed Web technologies. This fact has led to a new world of business, full of opportunities. Businesses can benefit now from faster communications, advanced methods of data collection, electronic chains of suppliers and other benefits offered by this new era of information processing. So, it is required a better level of security of the economic data, reason for what the role of cryptography is becoming increasingly higher. This paper reviews the progress in this area and points out some existent problems in digital chaotic ciphers. As a comprehensive solution to these problems,a novel pseudo-random bit generator based on a new couple of chaotic systems is presented. Detailed theoretical and statistical analyses show that it has perfect cryptographic properties, and it can be used to construct stream ciphers with higher security. Some experiments are made for confirmation.
