Design and Develop an Approach for Integrating Compression and Encryption on Textual Data

The primary intention of this research is to design and develop an approach for integrating compression and encryption on textual data. This improved approach can provide the better security with the aid of encryption and also, can provide better compression with the help of encoding procedure. The advantage of combining the encoding procedure with the encryption technique is that the attacks relevant to storage can be easily avoided since the data is fully within encoded domain also; the storage space required will be less due to good compression ratio. With the advantages of this, we have planned to utilize the dictionary-based encoding procedure and proposed encryption method to comcryption protocol (Compression + encryption). For integrating the compression and encryption, dictionary-based compression and the encryption based on permutation, sorting and reordering will be used. Dictionarybased methods are capable of giving better compression rate as like huffman encoding also follows dictionary-based method. Also, permutation, sorting and reordering-based methods can provide better security if these operations are included in the encryption protocol.
