In light of the current developments and the widespread use of the Internet and the sensitive data contained in images, it was necessary to develop new methods to protect data during its transmission.This paper will modify the E0 algorithm key generator by adding two additional records to the original generator to become 6, integrating them with dice to determine the choice of the bit resulting from the key, which increases the complexity and randomness of the generated key, additionally, included Peter De Jong's chaotic map features with image encryption procedure.The proposed method yielded promising results, as demonstrated by the NIST randomness test, confirming the generated key's randomness.Furthermore, the entropy values were close to the ideal value of 8, and correlation coefficients gives a good result close to 1, since all PSNR values are low, about 9.95dB the quality of the image encoding is good.In contrast to MSE around10128.22,all numbers are very high, indicating that the encoded image is very different from the original image.while the NPCR and UACI tests achieved about 99.60% and 33.50%, respectively.Other standard evaluations also confirmed that the proposed approach is robust against brute force attacks.
