Event-Native Symbolic-Temporal Spike Encoding Framework for Heterogeneous Cyber Streams
An event-native spike encoding framework lets recurrent spiking neural networks run intrusion detection directly on heterogeneous packet and CAN bus streams.
The paper maps heterogeneous cyber events—categorical identifiers, local frequency context, and inter-event timing—directly into sparse spike-compatible inputs for spiking neural networks. This avoids flow aggregation and fixed windows that add buffering latency and obscure temporal structure in traditional IDS pipelines. Compact recurrent SNNs under edge-oriented neuromorphic hardware constraints achieve a hybrid anomaly metric of 0.987 on packet-level Network IDS and 0.980 on message-level CAN IDS.
- Encodes categorical semantics, frequency context, and inter-event timing as spikes
- Avoids flow conversion, aggregation windows, and dense tensors
- Hybrid metric 0.987 on Network IDS and 0.980 on CAN IDS
From the original article
1 min read at arxiv.orgSpiking neural networks (SNNs) have shown promise for sparse, event-driven computation through stateful processing that is naturally compatible with low-power edge hardware. These properties align with cyber monitoring, where data arrives asynchronously, and malicious behavior often emerges through temporal patterns across event sequences.
