| Abstract(in English) | 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. On the other hand, it needs to be considered from different viewpoints from conventional ones. In this paper, we discuss the security of the block-based scrambled schemes against jigsaw-puzzle solvers. Block-based scrambled image encryption schemes are conventionally verified secure because the key space is large enough to be against a brute-force attack. The encrypted image has the same correlation blocks between the original ones despite the encryption. We compare divided blocks to jigsaw-puzzle pieces to verify the security of permutation-based image encryption schemes. Moreover, we conduct experiments with quantization noises image to evaluate the relation between security and noises. |
