Designers can now actively and economically protect their intellectual property and products, and make decisions about intrusions and physical attacks on the DeepCover security verifier Maxim DS28E38.
Cyber attacks are still important news, and IoT devices have weaknesses. However, many security experts believe that security is a time-consuming, expensive, and challenging task, or software should protect the system. In addition, security ICs and some of these simple, complex chips destroy this level of attack. These attacks are usually launched by the IC to obtain encryption keys and secure data.
Since the company has no other memory or static root keys, this is a physical technology feature and it is not possible to replicate the DS28E38 ChipDNA through an intrusive attack (PPU). In contrast, PUF technology relies on natural probability modeling of MOSFET-based semiconductor devices to generate keys. If necessary, the circuit generates a unique key for each device and disappears as soon as it is no longer used. If a device is subjected to a forced physical attack, the sensitive electrical characteristics of the circuit may change, further complicating violations. To protect this advantage, the technology eliminates or simplifies the need for integrated and secure IC key management because the key can be used directly for cryptographic operations. This circuit also has high reliability in terms of voltage, process, temperature and aging. In addition, in order to solve the problem of password quality, the PAP output will evaluate success based on the chaotic set of NIST tests. The device allows engineers to create projects from scratch to protect their projects from piracy. Low-cost integrated circuits combine a single 1-Wire service interface with complex, simple, fixed-function controls, including encryption, for easy integration into customer-designed products.
