Resilient Electronics & Cyber Resilience: Trends and Technologies
Cyber resilience is becoming a core requirement for networked electronics—driven by growing connectivity, new regulations such as the Cyber Resilience Act, and increasing security pressures in the industrial, automotive, and energy sectors. From November 10–13, 2026, at electronica in Munich, see how resilient electronics—from components to systems—is becoming a reality and how the industry is turning this into a strategic competitive advantage.
- Resilient electronics refers to systems that remain functional even under attack or failure conditions
- Geopolitical tensions and rising defense spending are driving massive demand for resilient electronics
- Security starts at the component level: MCUs, sensors, and communication modules are active components of the security architecture
- Secure-by-design and hardware root of trust are becoming market requirements
- The EU’s Cyber Resilience Act (CRA) sets binding requirements for products with digital elements—implementation deadline by 2027
- electronica 2026 is the central platform for experiencing solutions and standards for resilient electronics
In the future, secure electronic systems will determine whether connected products, factories, vehicles, and energy systems remain trustworthy. With increasingly digitized components, growing use of AI, and escalating geopolitical tensions, the attack surface is continuously expanding.
Since the onset of geopolitical tensions in Europe, nations have been investing heavily in defense systems, energy supply, critical infrastructure, and—as a direct consequence—in resilient electronics. This trend no longer benefits only traditional defense contractors, but increasingly also specialized electronics and technology providers with niche expertise.
What is resilient electronics?
Resilient electronics refers to electronic systems that do not simply fail in the event of attacks, malfunctions, or unexpected disruptions, but rather detect and limit disruptions, continue to operate in a controlled manner, and can be safely restored. While traditional requirements focus on functionality and reliability, resilience goes a step further: a resilient system must remain controllable even when attacks or errors cannot be completely prevented.
Components such as MCUs, sensors, communication modules, and power electronics are now active components of the security architecture. They determine whether a system can reliably verify identities, authenticate firmware, detect tampering, and perform secure updates. Cyber resilience is thus no longer an IT discipline, but a fundamental requirement for hardware, firmware, and system architecture.
Cybersecurity in Industry: From an IT Issue to System Architecture
Connected products, industrial plants, vehicles, and energy systems are increasingly based on embedded hardware and software, sensor technology, and updatable system architectures. Cybersecurity in industry is thus shifting away from traditional IT and into the entire lifecycle of electronic systems.
For developers, this means that security can no longer be added as an afterthought. Every additional interface, every OTA update, and every software-defined function expands the attack surface. A connected product must be continuously monitored, updated, and secured over many years. Value creation is thus shifting away from individual components toward resilient systems that companies operate, test, and further develop in the field.

Requirements for Resilient Electronics: Automotive, Industry, Energy, and IoT
Resilient electronics are required wherever electronic systems perform safety-critical functions and must meet regulatory requirements.
Automotive
In the automotive sector, resilient electronics are a must for software-defined vehicles, charging infrastructure, and fleet platforms. According to the BSI, wireless data interfaces and sensors in modern vehicles open up potential attack vectors—including via traffic infrastructure such as traffic lights and construction sites. UN R155, UN R156, and ISO/SAE 21434 provide binding standards. OEMs and suppliers must design control units, sensors, communication modules, and backend systems as an end-to-end security chain.

Industry 4.0 and Automation
Production facilities are networked cyber-physical systems. The ISA/IEC 62443 series of standards integrates operational and information technology, process safety, and cybersecurity. Industrial cybersecurity differs fundamentally from traditional IT security: the focus is on availability, process integrity, and controlled behavior in the event of a failure. An unplanned system shutdown caused by an update can be just as critical as an unpatched vulnerability.
Energy Generation and Storage
Smart grids, inverters, battery storage, and energy management systems are digitally controlled nodes of networked energy infrastructure. Manipulated control commands can affect grid quality and supply security. The NIS2 Directive establishes the legal framework for cybersecurity-compliant processes in 18 critical EU sectors, including energy.
IoT, Consumer Goods, and Medical Technology
In the IoT, security features such as Secure Boot, Hardware Root of Trust, and OTA updates must also function on cost-sensitive, low-power, and memory-constrained platforms. NIST describes IoT cybersecurity as an ecosystem-wide task spanning devices, products, and deployment environments. In medical technology, the EU guidelines MDCG 2019-16 require cybersecurity as a prerequisite for approval and safe operation.
Technologies: The Toolkit for Resilient Electronics
The Secure-by-Design approach integrates security requirements into component selection, system design, firmware, and interfaces starting from the concept phase. It is complemented by a zero-trust principle: No device, no interface, and no software update may be considered trustworthy without verification.
Key technologies at the component level:
- Root of Trust (RoT): The first element of a system accepted as reliable—whether hardware- or software-based (e.g., Intel Boot Guard, UEFI Secure Boot, Arm HAB).
- Secure Boot: A process that ensures only authenticated firmware is loaded during system startup.
- Trusted Platform Module (TPM): A tamper-resistant semiconductor chip for secure key storage and system integrity verification.
- Physical Unclonable Functions (PUFs): Unique, non-replicable hardware-based device identities (a digital "fingerprint" of the chip).
- Hardware Security Module (HSM) & Secure MCUs: Dedicated security controllers and cryptographic accelerators for hardware-based process protection.
With Edge AI, local AI models must be protected against data poisoning, model poisoning, and adversarial attacks. Resilient systems are not created by individual security components, but through a consistent architecture with verifiable processes, security tests, and a mature vulnerability management system.
Challenges for Resilient Electronics
In practice, the demand for resilient electronics faces technical, economic, and organizational trade-offs:
- Energy efficiency vs. security: On embedded systems, protection mechanisms compete directly with cost, power consumption, and space requirements.
- Time-to-market vs. resilience: Rapid development cycles clash with threat analyses, certifications, and long-term update responsibilities.
- Fragmentation of standards: IT security standards, industry-specific requirements, and communication standards intersect and complicate scaling.
- Supply Chains and AI Supply Chain Risks: The origin, authenticity, and integrity of components are becoming business-critical.
- Skills Shortage: Security must be embedded in development, testing, procurement, and lifecycle management—not just in specialized teams.
Future Trends: Resilient Electronics and Critical Infrastructure
The next phase of the electronics industry is characterized by demonstrable resilience:
Hardware Resilience as a Foundation
Hardware-based security is gaining importance because firmware, keys, identities, and recovery mechanisms require a resilient anchor of trust in the hardware. Updateability, verifiability, and lifecycle support are becoming key purchasing criteria.
AI as a Vulnerability and a Defense Tool
In driver assistance systems, predictive maintenance, and energy management, adversarial attacks can lead to incorrect decisions. AI supply chain risks are thus becoming a concrete procurement, testing, and governance issue for manufacturers, operators, and suppliers.
Software-defined products and new business models
Software-defined products are giving rise to new business models: Device-as-a-Service, Lifecycle Maintenance, and certified update services. What matters economically is no longer just the sale of a device, but also its secure and updatable operation throughout its entire lifecycle.
Post-Quantum Cryptography
Post-Quantum Cryptography is already relevant today for the automotive, energy, and industrial sectors: Cryptographic methods must be secured against future attacks by quantum computers.
Regulatory Framework: CRA, NIS2, and EU AI Act
In addition to technical requirements, a growing regulatory framework defines the rules of the game for resilient electronics. In the long term, products that are CRA-compliant, secure, and capable of being updated over the long term will be particularly successful:
- Cyber Resilience Act (CRA): Horizontal EU requirements for products with digital elements. Manufacturers must ensure security throughout the entire lifecycle. Implementation deadline: 2027.
- NIS2 Directive: Legal framework for cybersecurity processes in 18 critical EU sectors.
- EU AI Act (effective August 2024): Addresses AI security in edge devices and production systems.
- UN R155 / UN R156: Mandatory regulations for vehicle cybersecurity and software update management systems.
- ISA/IEC 62443: Series of standards for industrial automation and control systems.
- ETSI EN 303 645: Basic cybersecurity requirements for connected consumer devices in the IoT.
