Libraries may become a liability for users security. Existing studies show that libraries can be exploited to propagate malware. Hackers utilize fake or modified libraries to execute malicious behaviours. Vetting library instances in applications are desirable. However, it is impeded by the absence of robust library detection method and library vetting method. This paper proposes a hybrid library...
Android access control granularity based on its permission mechanism is relatively coarse, which cannot effectively protect the user privacy. Many Android applications do not strictly abide by the principle of least privilege (PLP). Both benign and malicious apps may request more permissions than those they really use. We rethink previous permission over-claim problem of Android applications, and...
Smartphone contains diverse sensitive private information, such as phone number, contact and credit. The Android platform employs permission mechanism to protect intensive information from illegal leakage. There are several tools to assist users to manage apps' permissions, such as App Ops, Privacy Guard, and XPrivacy. However, the permission mechanism of Android is complicated, and only a few of...
A core area of peer-to-peer (P2P) research is the overlay topology of the network. There are two main types of overlay topologies: structured and unstructured. The unstructured networks have excessive lookup costs, while the structured networks have many restraints between the shared data placement and topology characteristics of P2P networks. Hybrid peer-to-peer (P2P) networks that construct overlay...
Multi-domain application environments where distributed domains interoperate with each other are becoming a reality in Internet-based enterprise applications. The secure interoperation in a multi- domain environment is a challenging problem. Role- based access control (RBAC) is used for specifying the security requirements of multi-domain applications in this paper. Then, role mapping relationship...
