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.
