DS28EL25Q+U is an one-time programmable (OTP) secure EEPROM, which is designed and fabricated to meet the highest security requirements needed to protect sensitive information and intellectual property. It belongs to the Memory field. It is an ideal solution for secure data storage applications and embedded systems. The device integrates robust, secure authentication protocol and advanced security features to prevent confidential, sensitive data from unauthorized access or use. This article is an overview of the application field and working principle of the DS28EL25Q+U.
Application Field
The DS28EL25Q+U offers the highest levels of security and performance for any data storage application. It is suitable for applications like digital banking, medical devices, online identification, wearable electronics, automotive security systems, digital signature certificates, contactless smart cards, etc. The device can be incorporated into nearly any type of system, from stand-alone security systems to server-based architectures.
The device offers secure storage for private keys, passwords, certificates, passwords and other sensitive information. It also provides a secure authentication mechanism for verifying the user’s identity, such as secure logging in, access control and digital signature verification. The device supports a variety of secure authentication modes such as challenge-response authentication (CRAM) and proprietary authentication protocols. Additionally, the device can be used to secure signature and authentication credentials.
The DS28EL25Q+U can also be used in industrial applications, such as embedded systems and networking equipment, to securely store data and authenticate a device or system. The device supports a secure boot feature that prevents unauthorized code execution on the system and provides secure storage for firmware and bootloader images. Additionally, the device can be used to secure interactions between hardware and software components.
Working Principle
The DS28EL25Q+U is secured by a Smart Authenticator (SA) core, which is a 128-bit random number generator (RNG). The SA core is used to generate random numbers that are used to generate random keys and signatures. The device is programmed with a master key and a device key, which are used to encrypt data stored on the device.
The device supports multiple security protocols that offer different levels of protection depending on the application. The device supports the 128-bit Advanced Encryption Standard (AES) for data encryption, SHA-256 for secure authentication, and Elliptic Curve Cryptography (ECC) for digital signature authentication.
The device also supports secure identification and authentication algorithms such as challenge-response authentication (CRAM), public key authentication (RSA) and symmetric key authentication (AES). It also supports secure boot, an innovative feature that prevents unauthorized code execution on the system. With secure booting, only authenticated software can execute on the system.
Conclusion
The DS28EL25Q+U is a secure EEPROM designed to meet the most stringent security requirements. Its application field includes digital banking, medical devices, online identification, durable command and control systems, automotive security systems, and contactless smart cards, among others. It comes with robust security features such as AES encryption, SHA-256 authentication, and ECC digital signature authentication, and supports various secure authentication protocols. Its secure boot feature also prevents unauthorized code execution on the system. The device is an ideal solution for secure data storage applications and embedded systems.
