Impinj Cryptographic Authentication
The Impinj Cryptographic Authentication feature uses a challenge-response protocol to verify a product’s authenticity with RAIN RFID, preventing counterfeits, ensuring consumer safety, and securing the supply chain.
Why use Impinj Cryptographic Authentication?
Counterfeit items erode a brand’s integrity, cost customers and retailers millions every year, and threaten consumer safety. A key component of the Impinj Authenticity solution engine, Impinj Cryptographic Authentication allows select Impinj tag chips programmed with unique cryptographic keys to enable secure authentication requests. With product authentication solutions powered by the Impinj platform, fake and gray market products such as counterfeit jewelry, handbags, shoes, and medications can be identified before they enter the supply chain.
Available on select Impinj RAIN RFID tag chips, Impinj Cryptographic Authentication:
- Fits seamlessly within existing inventory management, loss prevention, and supply chain processes
- Integrates with existing Impinj-enabled M700 series tag inlay designs and RAIN RFID readers
- Uses universal GS1 and ISO standards-based authentication methods that are supported by a broad vendor ecosystem
Industries that benefit from Impinj Cryptographic Authentication
Combat counterfeits by quickly and automatically checking the authenticity of products in real-time
Spot patterns in product movement and respond where counterfeit products enter
Prevent gray-market medications and devices that can lead to recalls, legal action, and erosion of consumer trust
Comply with regulations and minimize costs associated with returns, recalls, or counterfeits

Protect consumer safety, ensure regulatory compliance, and avoid taxation loss by identifying bad products
How Impinj Cryptographic Authentication works
Cryptographic authentication is a process that combines a cryptographic key and a cryptographic engine with an authentication request and response. Impinj Cryptographic Authentication uses the EPCglobal Gen2 standard, which means this capability can work with a range of RAIN RFID systems and devices. Here’s how it works:
- The cryptographic key is programmed into each Impinj M775 RAIN RFID tag chip at the factory.
- When a RAIN RFID reader sends the Gen2 Authenticate command to a tag, a cryptographic challenge-response protocol is used to test whether the valid key for a specific Tag ID is in the chip.
- The response is authenticated by the cloud-based Impinj Authentication Service, which sends the challenge result to the user and confirms the tag’s authenticity.
