Design of Nonlinear Component of Block Cipher Using Gravesian Octonion Integers
IEEE Access, 2023 Being the only nonlinear component in many cryptosystems, an S-box is an integral part of modern symmetric ciphering techniques that creates randomness and increases confidentiality at the substitution stage of the encryption.

Real-time chaotic video encryption based on multithreaded parallel confusion and diffusion [PDF]
Information Sciences 666, 120420 (2024), 2023 Due to the strong correlation between adjacent pixels, most image encryption schemes perform multiple rounds of confusion and diffusion to protect the image against attacks. Such operations, however, are time-consuming, cannot meet the real-time requirements of video encryption.

A Color Image Encryption Using Dynamic DNA and 4-D Memristive Hyper-Chaos
IEEE Access, 2019 In this paper, a color image encryption is proposed based on the dynamic DNA and the 4-D memristive hyper-chaos. First, chaotic matrices are generated from the 4-D memristive hyper-chaos by using the plain image, the salt key, and control parameters ...

Comparative evaluation of different methods of "Homomorphic Encryption" and "Traditional Encryption" on a dataset with current problems and developments [PDF]
arXiv, 2022 A database is a prime target for cyber-attacks as it contains confidential, sensitive, or protected information. With the increasing sophistication of the internet and dependencies on internet data transmission, it has become vital to be aware of various encryption technologies and trends. It can assist in safeguarding private information and sensitive

Blind Functional Encryption [PDF]
, 2020 Functional encryption (FE) gives the power to retain control of sensitive information and is particularly suitable in several practical real-world use cases. Using this primitive, anyone having a specific functional decryption key (derived from some master secret key) could only obtain the evaluation of an authorized function f over a message m, given ...

Quantum fully homomorphic encryption scheme based on universal quantum circuit [PDF]
Quantum Information Processing, Volume 14, Issue 8 (2015), Page
2749-2759, 2014 Fully homomorphic encryption enables arbitrary computation on encrypted data without decrypting the data. Here it is studied in the context of quantum information processing. Based on universal quantum circuit, we present a quantum fully homomorphic encryption (QFHE) scheme, which permits arbitrary quantum transformation on an encrypted data.

Owner Specified Excessive Access Control for Attribute Based Encryption
IEEE Access, 2016 Attribute-based encryption (ABE) has emerged as a promising solution for access control to diverse set of users in cloud computing systems. Policy can just specify whether (or not) any specific user should be given access to data, but it lacks to provide
