Security homomorphic encryption scheme over the MSB in cloud

Abstract

Remote sensing has the characteristics of multi-temporal, multi-semantic and multi-spectral, and it plays an important role in most kinds of fields, so we should take some measures to protect the security of the remote sensing. With the rapid development of technology in three-dimensional remote sensing, it has promoted the remote sensing data growth explosively, and it has shown the big data characteristics obviously. Because of the non-complete trusted cloud environment, we consider a security homomorphic encryption scheme over the most significant bit in cloud, which can support the operation for ciphertext remote image in cloud.
