A Combination of Decimal- and Bit-Level Secure Multimedia Transmission
Mohamed Gabr, Hisham H. Hussein, Wassim Alexan · 2022
The proliferation of multimedia production and exchange over the Internet has created a dire need for security measures to protect it. In this paper, we propose a hybrid method for the encryption of images. This kind of hybrid strategy calls for the application of two (varying in nature) components, arithmetic (in the form of a dot product operation applied on the decimal level) and bit-level operations (in the form of an application of a PRNG key data change), alongside an S-Box (as a confusion application element). The incorporation of an arithmetic component leads to the development of an encryption scheme that is fundamentally distinct from the majority of algorithms in the state-of-the-art. The proposed scheme demonstrates strong encryption performance, as can be seen from the results of the conducted tests.
