TrafficAuth is powered by OmniTrust (formerly INTEGRITY Security Services)
TrafficAuth-SDK gives developers a secure, standards-based path to add Network V2X capabilities to mobility apps, fleet platforms, and connected devices — with SCMS certificate management, private key protection, and seamless access to the National Mobility Interchange built in.
TrafficAuth-SDK is a Software Development Kit that enables application developers and device manufacturers to add secure Network V2X capabilities to their own products.
The SDK is designed for teams that want to integrate V2X features into an existing mobile app, fleet platform, embedded device, driver interface, or connected transportation product without building the complex security and message exchange infrastructure from the ground up.
TrafficAuth-SDK works with the National Mobility Interchange, or NMI, to send and receive standards-compliant V2X messages over network connections. It also supports interoperability with Direct V2X systems by enabling applications to process the same signed V2X message content used by roadside units, onboard units, and connected infrastructure.
For developers, the result is a faster path to secure V2X integration.
Add V2X Without Becoming a Certificate Infrastructure Expert
V2X applications require more than data access. They require trust.
Applications must be able to receive signed messages, validate security properties, manage credentials, protect private keys, and interact with message routing infrastructure. For many app developers, fleet software teams, and device vendors, this creates a significant barrier to entry.
TrafficAuth-SDK abstracts that complexity.
The SDK provides the building blocks needed to add secure Network V2X features while handling the difficult security operations behind the scenes. This allows product teams to focus on the user experience, application logic, data presentation, and service integration rather than the details of SCMS certificate handling and V2X security workflows.
Connect Applications to Real-Time Transportation Data
TrafficAuth-SDK enables applications to connect to NMI and participate in Network V2X services.
Through NMI, applications can receive or publish trusted V2X messages related to smart intersections, work zones, fleet operations, vulnerable road user protection, signal priority, roadway alerts, and other connected transportation use cases.
This can support applications such as:
For example, a statewide 511 app can integrate TrafficAuth-SDK to display real-time regional alerts, intersection data, and V2X safety information directly inside the app, with end-to-end message security preserved.
Network Access to the Same Trusted Message Content
Many DOTs have already deployed Direct V2X infrastructure such as Roadside Units and On-Board Units. These systems use standards-based message formats and security models to exchange data locally over the 5.9 GHz safety band.
TrafficAuth-SDK helps applications participate in that same ecosystem through Network V2X.
When Direct V2X messages are relayed through NMI, applications using TrafficAuth-SDK can receive and process the same trusted V2X message content over a network connection. This allows mobile apps, fleet platforms, and connected devices to interoperate with infrastructure originally deployed for Direct V2X use cases.
For DOTs and developers, this helps preserve existing infrastructure investment while expanding access to more users and devices.
SCMS Certificates Built Into the Developer Experience
TrafficAuth-SDK supports end-to-end V2X security enabled by SCMS certificates.
The SDK helps applications acquire, use, and manage the credentials needed to sign and validate V2X messages. It abstracts the complex operations required to retrieve SCMS certificates, handle certificate lifecycle events, and protect private keys on a mobile or embedded device.
This is a critical part of V2X interoperability. NMI documentation describes V2X payloads as SAE J2735 messages protected with IEEE 1609.2 security wrappers and digital signatures, with certificate-based validation recommended for production systems.
With TrafficAuth-SDK, developers can integrate this trust model into their applications without implementing every low-level security operation themselves.
Protecting Credentials on Mobile and Embedded Platforms
TrafficAuth-SDK is designed to help protect sensitive credential material on supported platforms.
The SDK abstracts private key handling and supports secure key management patterns appropriate for mobile and connected device environments. For Android and iOS-based platforms, this can include use of native hardware-backed security capabilities where available.
This helps reduce the risk of exposing signing keys to application code, malware, or software-based attacks.
For hardware device vendors building automotive products on Android or iOS, TrafficAuth-SDK provides a practical path to add Network V2X security without designing a custom credential protection system.
Assign the Right Capabilities to the Right Devices
Not every V2X device or application should have the same authority.
A traveler information app may only need to receive trusted regional alerts. A fleet driver app may be authorized to request signal priority. A public safety application may require access to emergency preemption capabilities. A device installed at an intersection may be authorized to publish signed sensor data or infrastructure messages.
TrafficAuth-SDK works with the broader TrafficAuth permission model to support certificate-based authorization for groups of devices and users.
A mature permissions management capability makes it easier for DOTs, fleet operators, and account managers to authorize certificates with specific capabilities and apply those permissions across groups of devices.
Because permissions are tied to SCMS certificates, applications cannot simply enable restricted V2X functions in software. The proper credentials must be issued before advanced features can be used.
Built to Work with the National Mobility Interchange
TrafficAuth-SDK is designed to work seamlessly with NMI.
NMI provides the secure Network V2X message routing layer. TrafficAuth-SDK provides the developer integration layer for applications and devices that need to participate in that ecosystem.
Together, they allow applications to:
Statewide 511 Applications
A DOT can add TrafficAuth-SDK to a statewide 511 app to provide secure, real-time V2X information directly to travelers.
The app could display authenticated regional alerts, intersection information, work-zone messages, vulnerable road user warnings, or other transportation data delivered through NMI.
Fleet Driver Applications
A fleet operator can integrate TrafficAuth-SDK into an existing driver app to support signal timing awareness, safety alerts, vulnerable road user warnings, or DOT-approved signal priority services.
Automotive Android and iOS Devices
Hardware vendors building automotive products on Android or iOS can use TrafficAuth-SDK to add Network V2X connectivity and end-to-end security to their devices.
Smart City Applications
Mobility platforms, traffic dashboards, simulation systems, and connected infrastructure applications can use TrafficAuth-SDK to receive trusted V2X data from intersections, work zones, sensors, and regional transportation systems.
Roadside and Sensor Systems
Device vendors can use TrafficAuth-SDK to support secure message publication from connected infrastructure, including systems that generate alerts, sensor observations, or infrastructure status messages.

The Developer Path to Secure Network V2X
V2X adoption depends on more than roadside equipment. It depends on applications, fleets, devices, and platforms being able to participate securely.
TrafficAuth-SDK gives developers and device vendors a practical way to add Network V2X capabilities to their own products while preserving end-to-end security and interoperability with Direct V2X systems.
With SCMS certificate management, private key protection, permission-aware operation, and seamless NMI integration, TrafficAuth-SDK helps bring trusted V2X features into the apps and devices that DOTs, fleets, and travelers already use.
