In the paper, we use Microsoft’s Visual Studio Development Kit and the C# programming language to implement chaos-based electroencephalogram (EEG) encryption system with three encryption levels. A chaos logic map, an initial value, and a bifurcation parameter for the map are used to generate level I chaosbased EEG encryption bit streams. Two encryption-level parameters are added to these elemen...

Nowadays, protecting information is a major issue in any transmission system, as showed by an increasing number of research papers related to this topic. Optical encoding methods, such as a Double Random Phase encryption system i.e. DRP, are widely used and cited in the literature. DRP systems have very simple principle and they are easily applicable to most images (B&W, gray levels or color). ...

BACKGROUND The existing techniques for simultaneous encryption and compression of images refer lossy compression. Their reconstruction performances did not meet the accuracy of medical images because most of them have not been applicable to three-dimensional (3D) medical image volumes intrinsically represented by tensors. METHODS We propose a tensor-based algorithm using tensor compressive se...

Unclonable encryption, introduced by Broadbent and Lord (TQC’20), is an encryption scheme with the following attractive feature: given a ciphertext, adversary cannot create two ciphertexts both of which decrypt to same message as original ciphertext.We revisit this notion show following: 1. Reusability: The constructions proposed have disadvantage that they either guarantee one-time security (t...
