Some New Encryption Techniques Using Firewalls And Random Number Genera Tors

Abstract

ln this work, the researchers consider the concept of Information Security by the

application of firewall and encryption techniques. Also, the problem of explicitly

exposing infonnation in transit is discussed. We developed several algorithms. Among

the algorithms are those of random sequence and non-arithmetic sequence using modified

generators for the problem to secure information that may pass through intermediate

computers l inked in the Internet. Some of these algorithms employ modified random

generators in a crucial way. In all, four applications are presented. Firstly, we show that

generated random integers can represent the letters of the alphabets in the encrypted

information. This makes it possible for the encrypted information not to be easily

decrypted by cryptanalysts. Secondly, it is shown that before encrypting information,

such information is split into parts, and each part encrypted separately using a different

keyword. Before sending the encrypted information out, the various parts are combined

into a single stream. Thirdly, it is also shown that the optimal number of splits of

information to encrypt could be obtained, and result proves that the more the number of

splits, the more complex the information becomes to decrypt. Finally, our research

finding shows that encrypted information may be embedded in a computed decimal digit

and only revealed when corresponding decimal digit is computed by the information

recipient.
