Memory encryption

ACM Computing Surveys, 2014
Memory encryption has yet to be used at the core of operating system designs to provide confidentiality of code and data. As a result, numerous vulnerabilities exist at every level of the software stack. Three general approaches have evolved to rectify this problem.

Full Memory Encryption with Magnetoelectric In-Memory Computing

2019 International Symposium on VLSI Technology, Systems and Application (VLSI-TSA), 2019
We propose an in-memory computing architecture based on the magneto-electric random access memory (MeRAM). The unique precessional magnetism of MeRAM is utilized to carry out XOR encryption of the device state with a key, allowing for encryption without readout of the device state, thus saving a significant energy and delay over computing-in-memory ...

Optimized Memory Encryption for VMs Across Multiple Hosts

open access: yes, 2021
Recently, virtual machines (VMs) with a large amount of memory are widely used. It is often not easy to migrate such a large-memory VM because VM migration requires one large destination host. To address this issue, split migration divides the memory of a VM into small pieces and transfers them to multiple destination hosts.

The Memory-Tightness of Authenticated Encryption [PDF]

open access: yes, 2020
This paper initiates the study of the provable security of authenticated encryption (AE) in the memory-bounded setting. Recent works – Tessaro and Thiruvengadam (TCC ’18), Jaeger and Tessaro (EUROCRYPT ’19), and Dinur (EUROCRYPT ’20) – focus on confidentiality, and look at schemes for which trade-offs between the attacker’s memory and its data ...
