Hybrid Encryption Algorithm Over Wireless Communication Channels

Encryption and processing of digital data, has recently attracted the interest of researchers in the field of information security due to need for securing the information contents even through the processing stage. This thesis is concerned with different topics as survey study for data encryption algorithms and their drawbacks, study of encrypted data processing techniques, proposal of an efficient data processing techniques, proposal of an efficient data encryption algorithm that is robust to communication channel degradation, attacks and signal processing tools, providing a mathematical model for the proposed data encryption algorithm, proposal of data compression and authentication tools that can be performed on encrypted data without variation of the data content, and comparison study between the proposed approaches and the state of the art approaches--
