Abstract: Today’s technological era is highly dominated by data transfer. Since confidential data is transmitted over risky media like internet, faithful data transfer is now accompanied with secure data transfer. Security is the need of the hour. Here, a new and relatively simple encryption algorithm is proposed which shuffles the elements. It randomizes the data. But this algorithm is applied on compressed sensed data which inherently has encryption properties. A study of the security of this additional encryption algorithm over the compressed sensed data is done and observed the objective quality of the recovered data in presence of noise.
Keywords: Compressive sensing, Faithful data transfer, Objective quality, Security.
