An image encryption scheme is proposed using block cipher for remote sensing image in this paper. Remote sensing image means the detection of earth surface including mainly the land, ocean, and atmosphere from satellite. Due to the huge data in normal remote sensing image with security communication requirement, block encryption is adopted for fast implementation, which can effectively resist chosen and known plaintext attacks. Actually, it is a integer factorization problem in mathematics science. The factorization method is not secret but can be open. Some control parameters are produced from the plain-image of which shows that the new scheme can resist well the known-plaintext and chosen-plaintext attacks. Here, The Lorenz system in three-dimension is used for big key space. Classical encryption architecture, i.e., permutation and diffusion, is adopted for high security. All experimental results and security analyses show the efficiency of the proposed method. Therefore, it is suitable for secure communication of big remote sensing image.
