Selective encryption of visual data and especially MPEG has attracted a considerable number of researchers in recent years. Scalable visual formats are offering additional function...
Currently, the requirements on MPEG encryption algorithms include: fast speed, format compliance, a wide range of security levels, easy implementation, etc. However, promising can...
In this study we propose a new approach for selective encryption in the Huffman coding of the Discrete Cosine Transform (DCT) coefficients using the Advanced Encryption Standard (...
In this paper, we present two fully secure functional encryption schemes. Our first result is a fully secure attribute-based encryption (ABE) scheme. Previous constructions of AB...
