|Title in Arabic||تشفير البيانات بالاعتماد على ديناميكية المكان و سرعة الهاتف النقال|
The development of applications and services of mobile phone has created a phenomenon of spying and deception through these mobiles. So, it is necessary to think of finding solutions to overcome this problem. In this thesis, we propose a new method to protect data sent between mobile phones. This method depends on one of the available services to mobile phones, such as Global Position System (GPS), Wireless Fidelity (Wi-Fi) ,.., by using the coordinate that are read through these services. A mobile receiver with this location service registers a set of coordinates and velocity during movement and using the algorithm to estimates the next position after fixed time. Our proposed algorithm is to generate the secret key which uses this new coordinate and the dynamic tolerance distance (DTD) to increase its practicality. The security analysis in our practical implementation shows that the probability to break this key is almost impossible due to the dynamic coordinates and (DTD) and adjusting the length of the Random key. Our proposed solution is tested in real time using (J2ME) software where the experimental study shows that the cipher text (message) can only be decrypted under the restriction interval of (DTD). Our simulation illustrates that the proposed algorithm is more effective, practical, and promising for data transmission in mobile environment compared with existing solutions.
