Introduction

DS28E25G+U is a cryptographic memory device with a secure 32-byte UID that provides enhanced security and ease of use for over-the-air communications. It combines a secure-channel server and a secure storage device, providing features such as secure firmware updates and data storage, oracles, and strong authentication. This makes it an ideal crypto-memory device for secure IoT applications.

Application Field

DS28E25G+U is used in many applications such as consumer electronics, medical equipment, industrial automation, supply chain, automotive, smart home, and many more. It can be used as a secure storage channel in many products to protect consumer data, as well as providing secure communications between machines. It is also used to protect firmware and other sensitive information, to create strong authentication protocols, and to verify that the data being transmitted is legitimate.

In consumer electronics, DS28E25G+U can be used to secure the firmware updates and data storage of smartphones, tablets, and other consumer devices. In medical equipment, it can be used to securely store patient data and ensure it is only accessed by authorized personnel. In industrial automation, it can be used to secure embedded systems and ensure that only authorized personnel can access them. In automotive applications, it can be used to secure vehicle infotainment systems, as well as to protect the data being transmitted to and from the vehicle.

Working Principle

The DS28E25G+U works using a secure element, which is a secure block of memory or processor where all the information is securely stored and encrypted. The data is encrypted using 256-bit Advanced Encryption Standard (AES) encryption which ensures that only authorized personnel can access it.

The secure element is connected to a microprocessor and uses a secure authentication protocol to authenticate each user. The authentication protocol is based on an elliptic curve algorithm (ECDSA) which involves a series of mathematical operations to generate a unique signature for each user. This ensures that the data stored in the device is only accessible by authorized personnel.

The secure element includes a True Random Number Generator (TRNG) which is used to generate random numbers that are used in the authentication and encryption process. The TRNG adds an additional layer of security to the device as it generates a different random number each time it is used.

Once a user has been authenticated and the data has been encrypted, it is stored in the secure element in an encrypted format. The data can then be securely transmitted over the air or through a wired connection.

Conclusion

The DS28E25G+U is a secure memory device that provides enhanced security and ease of use for over-the-air communications. Its features, such as secure firmware updates and data storage, oracles, and strong authentication make it an ideal crypto-memory device for secure IoT applications. It can be used in a variety of applications such as consumer electronics, medical equipment, industrial automation, automotive, and many more. Its secure authentication protocol, 256-bit AES encryption, and True Random Number Generator ensure that the data stored in the device is only accessible by authorized personnel.
