With the ubiquity of the internet and advances in technology, especially digital consumer electronics, demand for online multimedia services is ever increasing. While it’s possible to achieve a great reduction in bandwidth utilization of multimedia data such as image and video through compression, security still remains a great concern. Traditional cryptographic algorithms/systems for data security are often not fast enough to process the vast amounts of data generated by the multimedia applications to meet the realtime constraints. Selective encryption is a new scheme for multimedia content protection. It involves encrypting only a portion of the data to reduce computational complexity(the amount of data to encrypt)while preserving a sufficient level of security. To achieve this, many selective encryption schemes are presented in different literatures. One of them is Wavelet Tree Shuffling. In this paper we assess the security of a wavelet tree shuffling encryption scheme.
