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

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 ...

An Image Encryption System by Cellular Automata with Memory

2008 Third International Conference on Availability, Reliability and Security, 2008
In this paper, an Image Encryption System by special kind of cellular automata (cellular automata with memory) and also an appropriate transition function for the cryptosystem have been proposed. Also a lossy idea is used to present a secure cryptosystem.

Memory predecryption

ACM SIGARCH Computer Architecture News, 2005
Memory encryption has become a common approach to providing a secure processing environment, but current schemes suffer from extra performance and storage overheads. This paper presents predecryption as a method of providing this security with less overhead by using well-known prefetching techniques to retrieve data from memory and perform decryption ...

Memory Encryption for General-Purpose Processors

IEEE Security & Privacy, 2016
Intel's Software Guard Extensions allows general-purpose computing platforms to run software in a trustworthy manner and securely handle encrypted data. To satisfy the technology's security goals, the external system memory must be cryptographically protected. A new hardware unit added to the processor's memory controller--the Memory Encryption Engine (

Invited: Accelerating Fully Homomorphic Encryption with Processing in Memory

2021 58th ACM/IEEE Design Automation Conference (DAC), 2021
Fully homomorphic encryption (FHE) provides a promising solution for future computing needs by allowing privacy-preserving computation. However, its practical use has been limited by the huge latency overhead it incurs while computing. This is primarily due to the huge size of encrypted data and intermediate processing required to compute on it.

Dynamic encryption key design and management for memory data encryption in embedded systems

2013 IEEE Computer Society Annual Symposium on VLSI (ISVLSI), 2013
To effectively encrypt data memory contents of an embedded processor, multiple keys which are dynamically changed are necessary. However, the resources required to store and manage these keys on-chip (so that they are secure) can be extensive. This paper presents a design where each dynamic key is determined by a random number, a counter value, and a ...

Encrypted Image Classification with Low Memory Footprint Using Fully Homomorphic Encryption

International Journal of Neural Systems
Classifying images has become a straightforward and accessible task, thanks to the advent of Deep Neural Networks. Nevertheless, not much attention is given to the privacy concerns associated with sensitive data contained in images. In this study, we propose a solution to this issue by exploring an intersection between Machine Learning and ...

Verifiable memory leakage-resilient dynamic searchable encryption

Journal of High Speed Networks, 2018
Searchable symmetric encryption (SSE) allows a data owner to outsource his encrypted data to a cloud server while retaining the ability to perform keyword search over encrypted data. The security guarantees of existing SSE schemes require that the adversary has no access to the data owner’s secret keys. Unfortunately, adversaries may get some or all of
