Overview

Modern industries increasingly rely on over-the-air (OTA) updates to enhance software functionality, optimize performance, and extend the lifespan of critical systems. However, updating software across distributed, heterogeneous environments presents significant challenges around security, scalability, and reliability.

Vortex’s solution addresses these challenges by providing a secure and resilient framework for managing OTA updates across diverse industries—including automotive, aerospace, drones, and agriculture. It ensures that organizations can safely and efficiently deploy updates while maintaining compliance with rigorous security and safety standards.

Challenge

OTA updates offer significant benefits, including improved device performance, new features, bug fixes, and reduced reliance on physical maintenance or recalls. Yet in sectors where safety and cybersecurity are paramount, implementing reliable OTA infrastructure is far from trivial.

Managing updates across single devices, fleets, or interconnected systems is especially complex when multiple suppliers contribute software components. Regulatory demands further increase the challenge, requiring compliance with stringent safety and cybersecurity protocols.

There is also a growing emphasis on sustainability. Industry and consumer expectations now call for solutions that extend device lifespans and reduce electronic waste. Secure OTA capabilities enable this shift by allowing ongoing improvements without hardware replacements.

Solution

Vortex’s OTA update solution is built on Uptane, a cutting-edge security framework designed for the safe delivery of software updates in safety-critical environments. It enables secure, verifiable updates across various platforms—including vehicles, drones, satellites, and more.

In this project, Uptane was implemented to support updates for:

  • Single devices
  • Groups of devices
  • Devices composed of multiple software components from different vendors

This flexibility is critical in sectors like automotive, where electronic control units (ECUs) from various suppliers must be managed cohesively.

Ongoing enhancements aim to improve the protocol further:

  • Use of Secure Hardware: Extending the trust-chain to hardware-based keys and providing security guarantees based on immutable properties.
  • Safety Procedures for Installation: Ensuring that any persistent attackers are removed during the update process.

These developments are designed to strengthen update integrity and system resilience, ensuring that Vortex’s solution remains robust and reliable.

Use cases & industry applications

Automotive

Vortex enables secure over-the-air updates for Electronic Control Units (ECUs) and subsystems across entire vehicle fleets. This ensures end-to-end software integrity, reduces the risk of failed updates, and supports compliance with evolving automotive safety standards. By integrating secure OTA mechanisms from the earliest stages of design—through virtual development environments—manufacturers can embed security and updateability directly into the software architecture. This proactive approach not only streamlines coordination across multiple suppliers but also mitigates long-term maintenance risks and compliance challenges. architecture, reducing long-term risks and compliance challenges.

Drones (AGV/UAV)

In drone operations, managing software updates across heterogeneous fleets has traditionally been fragmented and complex, with each manufacturer relying on proprietary OTA systems. Vortex simplifies this landscape by enabling centralized and secure software delivery across mixed drone fleets. Whether updates are deployed directly to individual drones or managed through base stations, the system ensures compatibility, reduces operational overhead, and maintains high security standards. This unified approach improves reliability, supports regulatory compliance, and enhances efficiency for drone applications in surveillance, logistics, and precision agriculture.

Defense

Secure firmware updates for mission-critical systems with minimized cyber exposure.

Agriculture

Up-to-date software for irrigation controllers, smart sprinklers, and autonomous machinery.

Aerospace

Reliable OTA management for satellites and ground systems—even in intermittently connected environments.

Results

  • Improved security and reliability: Robust protection against cyber threats, ensuring software integrity.
  • Streamlined update management: Secure, scalable updates for vehicles, drones, and critical infrastructure.
  • Operational efficiency: Reduced manual effort and failure rates in software delivery.
  • Lower risk and cost: Minimized operational disruptions and long-term maintenance expenses.
