A Contextual Usage Control Model
Original scientific paper The usage control model (UCON) is the latest major enhancement of traditional access control models. It enables subject and object attributes mutability and usage control continuity. However, with the model access permission may be denied as a result of the environmental changes even though the authorization and obligation requirements are met, thus causing disruptions...
متن کاملTrusted Isolation Environment: An Attestation Architecture with Usage Control Model
The Trusted Computing Group (TCG) proposed remote attestation as a solution for establishing trust among distributed applications. However, current TCG attestation architecture requires challengers to attest to every program loaded on the target platform, which will increase the attestation overhead and bring privacy leakage and other security risks. In this paper, we define a conceptual model ...
متن کاملVibration control of an automotive engine using active mounts
In this research, vibration control of national engine (EF7) using active mounts is studied for two different mounting layouts. The first layout is based on the current engine mounting of national engine (system of three passive mounts), but the hydraulic mount is substituted by an active mount. The other mounting layout contains 4 mounts, 2 of which are active ones and the others are passive m...
متن کاملContext-aware and adaptive usage control model
Information protection is a key issue for the acceptance and adoption of pervasive computing systems where various portable devices such as smart phones, Personal Digital Assistants (PDAs) and laptop computers are being used to share information and to access digital resources via wireless connection to the Internet. Because these are resources constrained devices and highly mobile, changes in ...
متن کاملLogical Model and Specification of Usage Control
The recent usage control model (UCON) is a foundation for next generation access control models with distinguishing properties of decision continuity and attribute mutability. A usage control decision is determined by combining authorizations, obligations, and conditions, presented as UCONABC core models by Park and Sandhu. Based on these core aspects, we develop a firstorder logic specificatio...
