Abstract: With the maturity and development of the Internet of things, the application scenarios of the Internet of things have become larger and larger, and the environment is more complex. This complex application environment has led to a large number of security problems, which have even evolved into a threat to personal safety. For example, in the vehicle networking environment, the attack on vehicle IT systems may lead to complete control of vehicles, thus causing a threat to passengers lives. In the medical environment, more and more medical devices, including implantable medical devices, fully have the function of network access. The data generated by the patients body belongs to the category of personal privacy, so there is a huge risk of information leakage. In the field of smart home, more and more smart appliances have become part of the Internet of things, including traditional refrigerators, televisions, washing machines, air conditioners, smoke sensing systems related to security, fire sprinkler systems, fingerprint locks, electronic cats eyes and so on. There are a lot of security management and privacy data security problems. As the underlying security infrastructure of the domestic cryptographic algorithm, how to reasonably apply in various scenarios has become an important task.
