Further Improvements of Fast Encryption Algoirthm for Multimedia

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...

Fast Encryption for Set{Top Technologies

In this paper we present two approaches to combine recent results of cryptographic research with the requirements of modern multimedia systems. The rst is to evaluate modern block ciphers in a JAVA{environment. The second approach is based on recent developments regarding fast Luby{Racko ciphers. Paradoxically, it deals with doing \high-bandwidth encryption with low-bandwidth smartcards". Also,...

Differential Chosen-Plaintext Cryptanalysis of an Improved Fast Encryption Algorithm for Multimedia (FEA-M)

This paper studies the security of an improved fast encryption algorithm for multimedia (FEA-M). A simple differential chosen-plaintext attack is proposed to completely break the improved FEA-M. The proposed attack is very efficient in complexity and needs only two pairs of chosen plaintext blocks.

A Fast Selective Video Encryption Using Alternate Frequency Transform

With commercialization of multimedia data over public networks security of multimedia data is a challenging issue. Further multimedia data is generally very large therefore it requires efficient compression to save transmission cost. In this manuscript a modified 4 point butterfly method is proposed to compute DCT for encoding of frames in video data. It has been experimentally compared with ex...
