CVMI: Next-Generation Native-Speed Virtual Machine Introspection for Secure Cloud Environments
Virtual Machine Introspection (VMI) is the foundational technology for modern cloud security, enabling intrusion detection, live forensics, and auditing. However, current VMI deployments (like LibVMI) are inherently host-based, operating within the hypervisor or privileged management domains. This introduces significant operational and security bottlenecks: it exposes the hypervisor to sophisticated attack vectors and creates a fundamental conflict of interest regarding tenant privacy and cloud provider incentives.
GuardShare: Secure Cloud Data Sharing System
Public cloud storage has become the backbone of modern enterprise collaboration, prized for its scalability, accessibility, and cost efficiency. Yet a case study of six mainstream cloud storage platforms reveals three persistent security gaps: the lack of native or universally available end-to-end encryption (E2EE), reliance on third-party key-management services that introduce additional trust assumptions and single points of failure, and inflexible or inefficient permission revocation.
Tackling Malware Threats on Android Environment
The prevalence of sophisticated malware threats has risen significantly, posing serious risks to computer systems by inflicting substantial damage, compromising sensitive data, and resulting in financial losses. Recent incidents, such as hackers targeting Android users with a trojanised version of the Telegram app , and Google suspending an e-commerce app Pinduoduo over malware concerns, highlight the urgency for robust mobile security solutions. It is noteworthy that Android devices, constituting approximately 70% of the global market share , are particularly vulnerable, emphasizing the critical importance of effective security measures in this widely utilised environment.
