CWE-1331: Improper Isolation of Shared Resources in Network On Chip (NoC)
Weakness ID : 1331
Structure : Simple
Abstraction : Base
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.
Extended Description
Typically, network on chips (NoC) have many internal resources that are shared between packets
from different trust domains. These resources include internal buffers, crossbars and switches,
individual ports, and channels. The sharing of resources causes contention and introduces
interference between differently trusted domains, which poses a security threat via a timing
channel, allowing attackers to infer data that belongs to a trusted agent. This may also result in
introducing network interference, resulting in degraded throughput and latency.
Relationships
The table(s) below shows the weaknesses and high level categories that are related to this
weakness. These relationships are defined as ChildOf, ParentOf, MemberOr and give insight to
similar items that may exist at higher and lower levels of abstraction. In addition, relationships such
as PeerOf and CanAlsoBe are defined to show similar weaknesses that may want to be explored.
