Abstract
In this paper we propose an modified model for the E0 stream cipher, which is the Encryption system used in the Bluetooth specification. The modified model is manipulated by adding a fifth linear feed back shift register (LFSR) to the main key stream generator of the E0 cipher. The contribution of this modification is indicated in increasing the computational complexity of Ophir Levy and Avishai Wool attack from 285 to 2125.25. Increasing the quality of encryption is also illustrated through different images encryption with the implementation of several measuring factors such as the correlation coefficient, the maximum deviation, and the irregular deviation.
