CyberBrain: Cybersecurity in BCI for Advanced Driver Assistance

This project focuses on designing and implementing a comprehensive cybersecurity framework for Brain-Computer Interface (BCI) systems in advanced driver assistance scenarios, specifically targeting Bitbrain Technologies S.L. products.

Project Overview

Cybersecurity in BCI has barely been studied in the literature, counting only with few and limited works implementing proofs of concept in marginal scenarios. Based on that, the main objective of CyberBrain is to design and implement a framework able to detect cyberattacks affecting the BCI lifecycle while using Bitbrain products. After analyzing the BCI and Bitbrain vulnerabilities and proposing a list of countermeasures, CyberBrain will design and deploy a set of cyberattacks targeting three challenging use cases that integrates Bitbrain products with an advanced driver assistance scenario. The cyberattacks impact will be measured by the framework through a set of metrics defined during the project and provided as outcome of CyberBrain. Finally, the previous contributions and additional private and public documents, paper, software, and videos will benefit Bitbrain and the BCI community, respectively.

Technical Architecture

BCI Cybersecurity Framework

The core of our framework focuses on protecting Brain-Computer Interface systems:

class BCICyberSecurity:
    def __init__(self, bitbrain_products):
        self.bci_monitor = BCILifecycleMonitor()
        self.threat_detector = BCICyberThreatDetector()
        self.response_system = BCIResponseSystem()
        self.metrics_collector = BCIMetricsCollector()

    def protect_bci_system(self, bci_data):
        # Monitor BCI lifecycle
        lifecycle_status = self.bci_monitor.analyze(bci_data)

        # Detect cyber threats
        threats = self.threat_detector.detect_threats(bci_data)

        # Implement countermeasures
        response = self.response_system.respond(threats)

        # Collect security metrics
        metrics = self.metrics_collector.collect(lifecycle_status, threats, response)

        return response, metrics

Advanced Driver Assistance Integration

We implement cybersecurity measures for automotive BCI applications:

$$S(t) = \text{BCI}_{\text{security}}(D(t), V(t), C(t))$$

Where $D(t)$ represents driver assistance data, $V(t)$ is vulnerability assessment, and $C(t)$ is countermeasure implementation.

Bitbrain Product Security

Our framework includes specialized protection for Bitbrain technologies:

class BitbrainSecurity:
    def __init__(self):
        self.product_analyzer = BitbrainProductAnalyzer()
        self.vulnerability_scanner = BCIVulnerabilityScanner()
        self.countermeasure_engine = CountermeasureEngine()

    def secure_bitbrain_products(self, product_data):
        # Analyze Bitbrain product vulnerabilities
        vulnerabilities = self.vulnerability_scanner.scan(product_data)

        # Generate countermeasures
        countermeasures = self.countermeasure_engine.generate(vulnerabilities)

        # Apply security measures
        secured_products = self.product_analyzer.apply_security(product_data, countermeasures)

        return secured_products
