Smart Cities

Atonomi secures and enhances smart city operations

It’s Not a Smart City Without Smart Security

Today more than half of the world’s population lives in urban areas and this is expected to grow to two-thirds of the population by 2050.

These dense populations combined with complex infrastructure create huge opportunities to improve billions of lives and generate new businesses.  Smart cities are coming—but so are hackers and other bad actors. Adaptive traffic lights, cameras, and parking meters are expected to reduce time in traffic and parking by 15%. Up to 80% of cities in the United States are expected to adopt IoT technology by the year 2025 and create almost $1.7 trillion in economic value globally.

Atonomi helps secure smart cities by enabling device manufacturers and smart city project leaders to build in blockchain-based immutable device identity and reputation tracking with the interoperability required to connect different devices and equipment types.

Security is absolutely required for smart cities. Here’s a look at why:

“Unfortunately … the security issues facing smart cities are unlike anything ever before seen.”

Network World

“Security may be the element which could bring a smart city down to its knees and city officials may not be doing enough to enforce security basics while being swept away on the tide of exciting new smart city ideas.”

Zero Day

“Smart cities are going to be a security nightmare … As smart city infrastructure proliferates, the stakes for protecting these digital foundations will only get higher.”

The Harvard Business Review

“86% of municipalities say they have already experienced an IoT-related security breach.”


Why Atonomi for

Smart Cities


Smart City Security & Centralized Command

By 2050, it’s estimated 70 percent of the world’s population will be living in cities. These cities must be smart. And they must be secure. The Atonomi trust environment brings blockchain-based device identity and reputation tracking to help secure the future of sensitive unmanned devices and equipment.

Small Footprint

Security is useless if it can’t fit onto your device. The Atonomi SDK is created for devices that measure their computing and storage resources in kilobytes—not megabytes or gigabytes.

Easy to Deploy

Just download our Atonomi Embedded SDK, and give your device the blockchain-based security of the Atonomi trust environment.

Works across Devices

The Atonomi trust environment is designed to work across all IoT devices, whether used for smart traffic systems, smart street lighting, smart parking, smart building, smart energy grid, smart water storage, treatment & distribution, smart waste & recycling management, environmental data reporting, smart transit, or a world of other uses. Atonomi can be deployed across all the spectrum of devices.

Security as a Market Differentiator

There are some 19,000 local governments in just the U.S. The value proposition from smart city solutions—are so attractive that small and medium-sized cities are joining large cities in deploying smart city solutions. But all smart cities—from the largest to the smallest—require security. Embedding Atonomi let’s you provide security as a market differentiator.

The Atonomi trust environment uses public/private key cryptography and blockchain technology to record the unique IoT device identity onto the immutable ledger. Deeply rooted device identity is the foundation of security. Atonomi also uses immutable identity and machine learning to track device reputation to identify aberrations that could indicate a device has been hacked or otherwise compromised.

A Quick Overview of Atonomi

Here's a quick look at the basic building blocks of the Atonomi trust environment

Device Identity

Immutable root identity, especially when linked with device reputation, enables interaction between known and trusted devices. Atonomi incorporates device identity using Elliptic Curve 25519 public/private key pairs created during either the device development or manufacturing process. The Atonomi embedded SDK uses the key pairs later during device registration with the Atonomi trust environment.

Device Registration

Device manufacturers register device IDs, including the device’s public key, with the Atonomi trust environment. The Atonomi smart contract includes a device registration function that writes new device IDs to the blockchain. The registered device ID, along with its public key, is later used during device activation.

Device Activation

When the IoT device is purchased by the end user, they receive activation instructions that send them to the Atonomi web portal where they will enter the device identifier for device activation onto the Atonomi trust environment. The Atonomi Embedded SDK, integrated into the application code by the developer or OEM, guides the end user through the activation process.

Device Validation

Devices that have been Atonomi-enabled via the Atonomi Embedded SDK and that have successfully registered and activated on the Atonomi trust environment can begin to utilize the Atonomi Validation functionality. Devices exchange their signed device identifier with other devices with which they want to transact. This enables secure device-to-device interactions.

Device Reputation

The Atonomi Embedded SDK provides a device Reputation Service that relays quality of service data from interactions between devices on the Atonomi trust environment. The device reputation  uses an algorithm to generate a behavioral score. Interactions are tracked by reputation auditors, and analyzed using AI and machine learning to detect aberrations signaling a compromised devices.
