An encryption technique based on the modulo operation is proposed. The technique is a one-to-one encryption–decryption single key algorithm. Fractal images are proposed to be used as a source of randomness to generate strong keys. The use of the proposed method is verified, both in the single image encryption–decryption, and in a real-time streaming application. The described algorithm provides a mechanism for controlling the strength of the keys. The advantages of the proposed method are discussed. A video setup is built and GUI software implemented to practically test this method. Numerical results of the test are provided and analyzed. Overall, the theoretically anticipated results are achieved, and the algorithm proven to be adept for real world cryptographic applications.
