The first type of specialized encryption scheme that can be used in secure outsourced storage we will look at is property-preserving encryption. This is encryption where some desired property of the plaintexts is intentionally leaked by the ciphertexts. The two main examples we will study are deterministic encryption, which preserves the equality property, and order preserving encryption, which...
Encryption is the widely used technique to offer security for video communication and considerable numbers of video encryption algorithms have been proposed. The paper explores the literature for already proposed video encryption algorithms with the focus on the working principle of already proposed video encryption schemes. This study is aimed to give readers a quick overview about various vid...
Now a day’s everyone storing there data in cloud because we can’t depends on hard drives if they crash one can’t have backup for ever data. Famous Cloud storage applications are Drop box, Google drive, Sky drive, Box, Amazon cloud drive, Surdoc and Apple icloud. In cloud data security is provided by various security algorithms. In our research we have chosen attribute based encryption technique...
We address the problems of whether t-circular-secure encryption can be based on (t − 1)-circular-secure encryption or on semantic (CPA) security, if t = 1. While for t = 1 a folklore construction, based on CPA-secure encryption, can be used to build a 1-circular-secure encryption with the same secret-key and message space, no such constructions are known for the bit-encryption case, which is of...
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...
