Description
The Network On Chip (NoC) does not isolate or incorrectly isolates its on-chip-fabric and internal resources such that they are shared between trusted and untrusted agents, creating timing channels.
Modes of Introduction:
– Architecture and Design
Related Weaknesses
Consequences
Confidentiality, Availability: DoS: Resource Consumption (Other), Varies by Context, Other
Attackers may infer data that belongs to a trusted agent; the methods used to perform this attack may result in noticeably increased resource consumption.
Potential Mitigations
Phase: Architecture and Design, Implementation
Description:
Implement priority-based arbitration inside the NoC and have dedicated buffers or virtual channels for routing secret data from trusted agents.
