SparkGrid: Blockchain Assisted Secure Query Scheduling and Dynamic Risk Assessment for Live Migration of Services in Apache Spark‐Based Grid Environment

IET Blockchain, Volume 5, Issue 1, January/December 2025.
Grid computing is an emerging technology that enabled the heterogeneous collection of data and provisioning of services to the users. Due to the high amount of incoming heterogeneous request, grid computing needs an efficient scheduling to reduce execution time and satisfy service level agreement (SLA) and quality of service (QoS) requirements.

HyperWallet: cryptocurrency wallet as a secure hypervisor-based application

EURASIP Journal on Information Security
We present VirtSecIO, a hypervisor-based platform for executing secure modules. VirtSecIO provides the modules with secure paths to peripheral devices, which can be shared between the modules and the operating system.

Reinforcing Cloud Attack Tolerance on a Large Scale: Advanced Blockchain Technologies With Hierarchical Risk and Smart Contracts

IET Blockchain, Volume 5, Issue 1, January/December 2025.
We propose a blockchain‐based system to enhance cloud systems' resilience against distributed denial of service attacks. Our approach integrates a hierarchical risk‐based attack tolerance mechanism with smart contracts, dynamically estimating risks at local, cluster, and global levels using Dempster–Shafer theory. Simulations show improved availability,

Integrity monitoring of virtual machines components based on the KVM hypervisor

Безопасность информационных технологий, 2020
Today, virtualization is widely used to provide scalable resources. Since this technology means sharing resources using some abstract layer, the placement and processing of information of various access levels in such systems poses a security risk.

enCloud: Aspect‐oriented trusted service migration on SGX‐enabled cloud VM

Software: Practice and Experience, Volume 54, Issue 12, Page 2454-2480, December 2024.
Abstract This paper presents enCloud, a new aspect‐oriented trusted service migration with SGX‐enabled cloud VM. Addressing the challenge of reconciling end‐to‐end security with VM migration, enCloud incorporates two key aspects: (1) end‐to‐end security for enclave context migration, and (2) VM abstraction for conventional VM context migration.
