Programming Shape Memory Hydrogel to a Pre‐Encoded Static Deformation toward Hierarchical Morphological Information Encryption

Advanced Functional Materials, 2022
Morphological information encryption such as gesture and sign language is a traditional but efficient way of information storage and communication. However, due to the limited deformability, almost all of the existing information encryption materials ...

A Novel Covert Channel Attack Using Memory Encryption Engine Cache

Design Automation Conference, 2019
Microarchitectural covert channel attack is a threat when multiple tenants share hardware resources such as last-level cache. In this work, we propose a novel covert channel attack that exploits new microarchitecture that have been introduced to support ...

Integrating Photorewritable Fluorescent Information in Shape‐Memory Organohydrogel Toward Dual Encryption

Advanced Optical Materials, 2022
As one of the severe global problems, counterfeiting information has brought a huge negative impact on every aspect of human society. Though various anticounterfeiting strategies, including fluorescent materials, are widely developed for dealing with the

Attacks on Encrypted Memory and Constructions for Memory Protection

2016 Workshop on Fault Diagnosis and Tolerance in Cryptography (FDTC), 2016
The first part of the talk discusses some potential implications of attacks on the system memory of a computing platform. We show that encryption to protect privacy is not necessarily sufficient to protect against active attacks. In the second part of the talk, we explore the Memory Encryption Engine, which is part of Intel's Software Guard Extensions (

Memory protection challenges: Attacks on memory encryption

Cyber Security: A Peer-Reviewed Journal, 2017
This paper explains some of the challenges involved in protecting the system memory of a computing platform against adversaries who can read and modify its contents. To clarify the limitations and effectiveness of different defence mechanisms, we lay out a threat model, coupled with a set of assumptions on the adversarial capabilities, for a variety of

A High-Performance Transparent Memory Data Encryption and Authentication Scheme Based on Ascon Cipher

IEEE Transactions on Very Large Scale Integration (vlsi) Systems
The arbitrarily connected nature of IoT has led to an explosion in the number of embedded devices accessed. These devices typically store and process large amounts of private and critical data. Most of these data are transmitted in plaintext over the bus,

A Memory Efficient Network Encryption Scheme

2009
In this paper, we studied the two widely used encryption schemes in network applications. Shortcomings have been found in both schemes, as these schemes consume either more memory to gain high throughput or low memory with low throughput. The need has aroused for a scheme that has low memory requirements and in the same time possesses high speed, as ...

Secure optical memory system with polarization encryption

Applied Optics, 2001
A novel secure holographic memory system with polarization encoding is proposed. Two-dimensional original data are encoded as a two-dimensional polarization distribution. The polarization state at each pixel is scrambled by a mask that changes the polarization state into a random state.

Enhancement of the angular selectivity in encrypted holographic memory

Applied Optics, 2004
Enhancement of the angular selectivity in a double random-phase encoded holographic memory by use of reference plane waves is presented. In the storage algorithm, the angular selectivity is improved with the effect of random-phase masks. We show that the angular selectivity achieved by this scheme is more sensitive than that for Bragg angle detuning in
