Abstract
The security of medical images has attracted much
attention recently, especially when these images are hosted by
third party cloud service providers and therefore must be sent
through the communication networks. A key challenge in the
cloud computing paradigm is the design of efficient security
schemes that help address the issues of confidentiality,
integrity and authentication. Consequently, we propose a fast
and robust encryption technique for gray scale medical images
for real time applications. Our technique first compresses the
medical image in the discrete wavelet transform (DWT)
domain before encrypting with an algorithm based on basic
pixel permutation and randomness. In the DWT domain,
correlation and redundancy are reduced while random pixel
permutation with encryption key provides confusion and
diffusion. Our simulation results demonstrate the potentials of
our technique.
