For a low-cost device in M0 like MSPM0C110x, there are no hardware registers available to help implement SWD protection with a password, but only the fully open or completely disabled options can be chosen. However, with the popularity of cybersecurity, more and more applications, especially for the automotive market, are requesting this password-protected function. This application note proposes a new way to realize this security function based on software for a low-cost device, which does not have hardware to support the device.

With the deep integration of network communications, artificial intelligence, internet applications and other technologies with the automotive industry, intelligent connected vehicles have become the strategic direction of the automotive industry. And with the evolution of technology, the information security issues of intelligent connected vehicles are becoming increasingly severe, especially in recent years, there have been many automobile information security recall incidents, which have aroused great concern in the industry.
In June 2023, the United Nations World Forum for Harmonization of Vehicle Regulations (abbreviated as UN/WP.29) issued the world's first mandatory automobile information security regulation R155, namely Cybersecurity.
The series of regulations requires that all models in all EU countries and other OECD countries must pass relevant certification from July 2024. The regulations clearly state that there are process measures to control related risks throughout the vehicle life cycle, including that vehicle manufacturers must have measures to monitor security threats and detect and prevent cyber attacks.
As for China, although this is not mandatory to meet information security requirements, the cars must pass relevant certification as long as the cars are sold in these countries. And, with the increasing attention paid to information security, the demand for this function is also growing.
