Stiff Frame Encryption Using Compression

Abstract

This paper introduces a new encryption mechanism implemented over lossless data compression mechanisms. Our approach is applied to ASCII data and is implemented in two phases that are applied on independent frames of size nine bytes extracted from the input data. First phase implements compression, and second phase does compression as well as encryption. Each phase reduces one byte in frames, thereby resulting in two bytes reduction per each frame. Experimental results reveal that it achieves better compression ratios and also encrypts data with better key sizes. The proposed method is very economical and speedy method of doing compression and encryption at the same time of scanning input data.
