While this is a rudimentary example, more complex, real-world applications would use Converge to create large-scale, interconnected networks, feed in diverse data sources, and simulate the network’s behavior over time.
Firstly, ensure you have a compatible environment to run Converge. Check the official Converge documentation for setup and installation instructions.
Neurons are the fundamental units of a neuromorphic system. In Converge, you define neurons with their unique properties like so:
neuron LIF {
membrane_time_constant = 20 ms
threshold_voltage = 1.0 V
}
This creates a layer named Input with 100 LIF neurons.
You can apply stimulus patterns to layers:
pattern stimulus[100] = TimeSeries("./data/input.csv")
apply stimulus -> Input
Finally, to run the simulation:
run for 1 s
Neuromorphic computing, with its inspiration drawn from human neural networks, presents a unique set of challenges and vulnerabilities. One of the most exciting yet challenging avenues of this field is the emulation of disordered neurological phenomena for the purposes of testing, improving, and securing neuromorphic architectures. Below are prime examples of attacks inspired by various neurological disorders, each employing distinct attack vectors like malware, DDoS attacks, false data injection, rollbacks, and packet sniffing.
- Deploying malware that introduces erratic spike patterns similar to the disordered thinking observed in schizophrenia.
- Generating DDoS attacks that mimic the overwhelming sensory input associated with hallucinations.
Sample Code in Converge:
malware SchizoMalware {
erratic_spike("TargetLayer", "./data/erratic_spike.csv")
DDoS("TargetLayer", 1000, "sensory_hallucination")
}
- Systems overwhelmed with disorganized data, leading to false decisions.
- Resource exhaustion due to handling hallucinatory-like DDoS attacks.
- Injecting false data into memory storage components to mimic memory loss.
- Manipulating saved states and forcing rollbacks to simulate cognitive decline.
Sample Code in Converge:
malware AlzheimerMalware {
inject_false_data("MemoryLayer", "./data/false_data.csv")
force_rollback("MemoryLayer", "saved_state_1")
}
- Information corruption leading to faulty decision-making.
- Rollbacks causing loss of crucial data and system state, mimicking cognitive decline.
- Using packet sniffing to intercept data and then injecting extreme values to make the system oscillate between states, resembling bipolar mood swings.
- Introducing malware that forces the neuromorphic system into cycles of high and low activity, simulating mania and depression.
Sample Code in Converge:
malware BipolarMalware {
sniff_and_inject("DataChannel", "./data/extreme_values.csv")
activity_cycle("ProcessingLayer", "high", "low")
}
- System oscillation causing hardware stress and potential failure.
- Erratic behavior leading to inconsistent and unreliable outputs.
- Injecting false data streams to alter the system’s perception of reality, akin to psychosis.
- Introducing low-energy states or inactivity cycles to mimic depressive episodes.
Sample Code in Converge:
malware PsychosisDepressionMalware {
inject_reality("PerceptionLayer", "./data/false_reality.csv")
induce_low_energy("ProcessingLayer")
}
- Altered data causing incorrect decisions based on false reality.
- System inactivity leading to resource wastage and failure to respond to actual stimuli.
