Insufficient properties of image encryption algorithms
This work addresses security vulnerabilities in image encryption for applications like secure communication, but it is incremental as it critiques existing methods without introducing a new solution.
The authors analyzed a recent image encryption scheme and demonstrated its insecurity, revealing that the security evaluation methods used were insufficient. They designed a Deliberately Weak Cipher to show that relying on statistical properties alone is inadequate for solid security analysis.
We analyze the security of recently proposed image encryption scheme [1]. We show that the scheme is insecure and the methods used to evaluate its security are insufficient. By designing the Deliberately Weak Cipher, a completely vulnerable cipher with good statistical properties, we illustrate our main point -- a solid analysis cannot be replaced by some selected set of statistical properties.
