Experiments on a secure compression algorithm

Abstract

A compression tool can provide security to some degree, if the algorithm itself is kept secret. Whenever the algorithm is known, as is the case for conventional compression, we can not expect secrecy out of the tool. If security is needed as well, compression can be combined with encryption.To employ a system that would afford security while compressing, a novel technique (named as secure compression -SeCom) has been designed and implemented. We present the experimental results obtained by applying this scheme on texts from English and Turkish corpora. The results are promising in terms of compression quality and throughput, measured in bpc and MB/min, respectively.

Hybrid Encryption-Compression Scheme Based on Multiple Parameter Discrete Fractional Fourier Transform with Eigen Vector Decomposition Algorithm

“…Unnikrishnan and Singh [7,8,28] first proposed an optical encryption method using random phase encoding in the fractional Fourier domain and its opticallyimplemented approach. There is various lossy and lossless compression approaches also discussed in literature by researcher in [45,46,47,48,49,50,51] using different transform like wavelet, discrete cosine transform, Fractional cosine transform and FRFT etc.…”
