Three Techniques for Enhancing Chaos-Based Joint Compression and Encryption Schemes
Entropy, 2019 In this work, three techniques for enhancing various chaos-based joint compression and encryption (JCAE) schemes are proposed. They respectively improved the execution time, compression ratio, and estimation accuracy of three different chaos-based JCAE ...

Revisiting Fully Homomorphic Encryption Schemes [PDF]
arXiv, 2023 Homomorphic encryption is a sophisticated encryption technique that allows computations on encrypted data to be done without the requirement for decryption. This trait makes homomorphic encryption appropriate for safe computation in sensitive data scenarios, such as cloud computing, medical data exchange, and financial transactions.

Designing Secure Heterogeneous Multicore Systems from Untrusted Components
Cryptography, 2018 In current systems-on-chip (SoCs) designs, processing elements, i.e., intellectual property (IP) cores, may come from different providers, and executable code may have varying levels of trust, all executing on the same compute platform and sharing ...

On the Optimality of Quantum Encryption Schemes
, 2005 It is well known that n bits of entropy are necessary and sufficient to perfectly encrypt n bits (one-time pad). Even if we allow the encryption to be approximate, the amount of entropy needed doesn't asymptotically change.

Prevention of Crypto-Ransomware Using a Pre-Encryption Detection Algorithm
Computers, 2019 Ransomware is a relatively new type of intrusion attack, and is made with the objective of extorting a ransom from its victim. There are several types of ransomware attacks, but the present paper focuses only upon the crypto-ransomware, because it makes ...
