The DS28E25Q+U is a device built on the 1-Wire protocol that serves as a secure, non-volatile memory for product authentication, firmwares, identification, and credentials. It is designed to provide product developers the capability to securely store and process digital credentials for product authentication in a small package. This article will explain the application fields and working principle of the DS28E25Q+U.

The user application fields of the DS28E25Q+U include secure product/firmware authentication, durable credentials storage, and secure identification. 1-Wire devices use serial protocols and data transactions to store, monitor, and track products throughout their life cycle. The device allows for secure storage of the product’s authentication credentials and other related data, which can be used to rapidly authenticate the product in the field. This allows for product designers to securely authenticate products in development, production, and post-production.

The durable credentials storage capability of the DS28E25Q+U allows for secure storage of end user credentials such as passwords, PINs, serial numbers, or other unique data points. These credentials can be securely stored and used for authentication or identification. When combined with the secure product authentication capabilities, the device is an ideal solution for secure identification and authentication of individual users.

The DS28E25Q+U also provides secure identification capabilities. It uses a cryptographic hash algorithm to verify a product’s identity. This provides a secure way to ensure the authenticity of a product or identify individuals based on their stored credentials. This allows for individual authentication and secure identification of users.

The working principle of the DS28E25Q+U is based on the 1-Wire protocol. 1-Wire is a serial protocol that is used to create a network of connected devices. The DS28E25Q+U uses the 1-Wire protocol to securely store and read data from the device. The device stores data in a non-volatile memory, so it can retain the data even if the device is powered off. It also provides secure authentication using a cryptographic hash algorithm to ensure the device’s identity and verify its credentials.

The DS28E25Q+U is an ideal solution for product authentication, durable credentials storage, and secure identification. Its 1-Wire protocol based design and cryptographic hash algorithm provide the necessary security for these applications. By understanding the application fields and working principle of the DS28E25Q+U, product developers can use this device to securely store and read data from their products.
