Abstract: This paper proposes a new approach towards efficient image cryptography that works using the concepts of BITplane decomposition and bit-level scrambling. This method does not require the involvement of additional or extra images. Users have the flexibility of choosing: 1) any BITplane decomposition method; 2) logic that runs the key generation block; 3) customisation in the bit-level permutations performed during scrambling. The implementation of the method is simple and free of heavily complex steps and operations. This makes the algorithm applicable in a real-world scenario. The BITSAT algorithm is applied to a variety of images and consequently, the encrypted images generated showcase a high level of encryption. The analysis and evaluation of the algorithm and its security aspects are performed and described in detail. The paper also presents the application domains of the method. Overall, the results and analysis indicate a positive working scope and suitability for real-life applications.
