On the security of an image encryption method
The security of digital images attracts much attention recently, and many different image encryption methods have been proposed. In 1999, J.-C. Yen and J.-I. Guo proposed a novel image encryption algorithm called BRIE (Bit Recirculation Image Encryption). This paper points out that BRIE is not secure enough from strict cryptographic viewpoint. It has been found that some defects exist in BRIE, ...
متن کاملOn the security defects of an image encryption scheme
This paper studies the security of a recently-proposed chaos-based image encryption scheme, and points out the following problems: 1) there exist a number of invalid keys and weak keys, and some keys are partially equivalent for encryption/decryption; 2) given one chosen plain-image, a subkey K10 can be guessed with a smaller computational complexity than that of the simple brute-force attack; ...

This paper studies the security of a recently-proposed image encryption scheme based on chaos, and points out the following problems: 1) there exist a number of invalid keys and weak keys, and some keys are partially equivalent for the encryption/decryption processes; 2) given one chosen plain-image, a sub-key K10 can be guessed with a smaller computational complexity than that of the simple br...
متن کاملJoint Fingerprinting/Encryption for Medical Image Security
Electronic health records (EHRs) facilitates the healthcare process. However, it can also cause serious security and privacy problems. While various conventional encryption mechanisms can solve some aspects of these problems, they cannot address the illegal distribution of decrypted medical images. To protect decrypted medical images from being illegally distributed by an authorized staff membe...
متن کاملSecurity Definitive Parameters for Image Encryption Techniques
In present days safeguarding information, in form of images is very important, and it is done by various ways. Certain security analysis tests are done to find out the quality of image encryption algorithms to produce encrypted image from original image. Keywords— Differential analysis, Encryption quality performance, Features of image encryption, Information entropy analysis, Key space analysi...
