Key strength with encryption and dynamic location of mobile phone

This paper presents a new effective method for MMS message encryption which employs a new key to protect data sent between mobile phones. The novelty of this work lies in the dynamic location and speed of mobile devise which are generated by registering a set of coordinates and velocity during movement and estimate the next position. Dynamic tolerance distance (DTD) are applied in the algorithm 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. The resulting encrypted data is found to be fully distorted, resulting in increasing the robustness of the proposed work. The simulation results validate the proposed data encryption scheme.
