Block-based scrambled image encryption schemes have superior features that are compressible and against noises to number theory-based encryption
methods such as RSA and DES.
In this paper, we discuss the security of the block-based scrambled schemes
against jigsaw-puzzle solvers.
The security of Block-based scrambled image encryption schemes have been conventionally verified based on the key space under the assumption of a brute-force attack.
However, jigsaw puzzle solvers can be used as a attack schemes because the encrypted image has the same correlation blocks between the original ones despite the encryption.
Then, a new jigsaw puzzle solver is proposed to extend some limitations of the conventional ones.
In the experiments, the jigsaw puzzle solvers are applied to encrypted images to consider the security conditions of the schemes. |
