This paper demonstrates three modified algorithms for Logistic map utilized for image cryptosystem. The original Logistic map has a small range for key space. The three modified algorithms increased Key space range due to the expansion of the original Logistic map parameter. According to an increase in the parameter range, the Key space range will be wider than in the original Logistic map, hence withstands brute-force attack. The modified algorithm presents a good evaluation analysis such as encryption quality and security analysis.
