From remote network attacks to the manufacture of counterfeit products, the spread of security threats is becoming more widespread, affecting all industries. The success of these threats, which means that the cost of recovery, the huge loss of service revenue, of course, the most obvious is the loss of brand equity. Therefore, it is critical that powerful security features be implemented in new and existing designs to protect intellectual property (IP) and enable trusted authentication of networked devices. To prevent these threats, Microchip Technology Inc. (Microchip Technology Inc.) announced the release of the ATECC608A CryptoAuthentication device, which developers can use to add hardware-based security features to their designs. Microchip also has a Security Design Partner Program to help developers connect with third-party partners to enhance and accelerate security design.

The basis of secure communications is the ability to create, secure and authenticate the device's unique and trusted identity. By separating the device's private key from the system, placing it in a secure area, and incorporating industry-leading encryption, the ATECC608A provides a high level of security that can be used in almost any type of design. Key features of the ATECC608A include:

Best-in-Class Key Generation: Federal Information Processing Standards (FIPS) compliant random number generator (RNG) generates a unique key that meets the latest requirements of the National Institute of Standards and Technology (NIST) for FIPS certification of the entire system Provide a more simple way.

Boot Authentication for Small Systems: The new commands facilitate signature verification and summary calculations for firmware on main MCUs that use systems such as ARM® Cortex®-M0 + and more robust embedded systems.

Trusted Certifications for LoRa Nodes: The AES-128 engine enables secure deployment of the LoRa infrastructure by enabling authentication of trusted nodes in the network.

Fast Encryption Processing: Hardware-based integrated elliptic curve cryptography (ECC) algorithms enable faster, more secure creation of smaller keys and establishment of a certificate-based trusted root compared to other implementations that rely on traditional methods.

Tamper Protection: Tamper Protection protects keys from physical attacks and prevents intrusion attempts after deployment. These technical support systems store secure and trusted identity information.

Trusted Manufacturing Configurator: Companies can use Microchip's secure manufacturing facilities to securely configure their keys and certificates, thereby eliminating the risk of compromising the manufacturing process.
