Security in MCUs

In an increasing networked world where data transfer traffic is expected to nearly double each decade, there is a growing concern for security, privacy and safety. Texas Instruments provides security solutions with features that allow our customers to prevent, detect and respond to unintended or malicious behavior caused by outside influences in order to protect customer’s devices, solutions and services.

TI security solutions in MCU offer many advantages:

  • Symmetric cryptography provides a secure communication.
  • Hash function offer authentication and anti-cloning solution to protect manufacturers and consumers from spurious after-market and counterfeit accessories, disposables and replacement parts.
  • IP protection protects customer-developed algorithms, source code from read and write. So malicious and dangerous code can’t be inserted into the device with IP protection.
  • Tamper protection help to seal customer’s application. Protect devices against retrieving and modifying the system and the information.
