Analysis and development of cryptographic algorithms implementable in portable telecommunication devices with limited computational resources
Summary:
In this thesis, we study the requirements for the cryptographic protection of voice communications accomplished using portable telecommunication devices with limited computational resources, provided either by telecommunication providers or by Internet via VOIP applications. A typical example of such a device is a smartphone.

Initially, we introduce the reader to the term of "Cryptology", we study the mathematical background required for the foundation and further analysis of the cryptographic algorithms and we quote the chronology of telecommunication, emphasising in the recent progress. Also, we refer to the rudiments of cryptographic algorithms, by analyzing their basic categories.

Following, we study the most important cryptographic algorithms concerning the protection of voice in mobile telecommunications, presenting their strength against known cryptanalytic techniques that have been used against them.

The ultimate goal of this thesis is the development of new cryptographic algorithms, whom computational cost will encourage the integration of them in high security portable devices, in order to be widely usable from people that now either not have secure communication channels or are based on security methods that are embedded to the products by the service or other providers.
