Proposing an effective approach for Network security and multimedia documents classically using encryption and watermarking

Local binary pattern (LBP) operators, which measure the local contrast within a pixel's neighborhood, successfully applied to texture analysis, visual inspection, and image retrieval. In this paper, we recommend a semi blind and informed watermarking approach. The watermark has been built from the original image using Weber Law. The approach aims is to present a high robustness and imperceptibi...

On 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; ...

On the Security of a Class of Image Encryption Scheme

Recently four chaos-based image encryption schemes were proposed. Essentially, the four schemes can be classified as one class, which is composed of two basic parts: position permutation and diffusion of pixel value with the same cipher-text feedback function. The operations involved in the two basic parts are determined by a random number sequence generated by iterating a chaotic dynamic syste...

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...

Toward an Inverse-free Lightweight Encryption Scheme for IoT

The current IoT (Internet of Things) systems cannot provide the overhead caused by existing encryption scheme for confidentiality. Thus, the development of lightweight encryption schemes is necessary without degrading the system performance. In this paper, we introduce a well-known lightweight encryption scheme, PRINCE, and a method to enrich the message space of PRINCE by introducing XLS (eXte...
