AI Technical Summary

Problems solved by technology

For a wireless sensor network, it mainly faces three aspects of security issues: one is signal interference from the wireless communication process, such as attackers can block wireless communication by interfering with the communication frequency; the other is from self-organizing wireless network The problem of link vulnerability and simple network protocol, attackers can counterfeit and tamper with the transmitted information; the third is from the sensor node itself, such as the energy of ordinary low-power sensors or nodes is limited, it is difficult to load complex security Protection measures, easy to be captured and counterfeited

[0006] At present, most of the wireless sensor network node devices used at home and abroad do not perform data encryption and decryption, or only perform data encryption and decryption with symmetric algorithms, without high-security identity authentication functions, and cannot implement high-complexity security algorithms.

From the attacker's point of view, data security in such an open environment is low, the encryption key of the data transmitted over the network is easily cracked, and sensitive information is easily obtained through statistical methods

In any case, hardware is the basic condition. If the hardware does not meet the requirements, the security function cannot be realized.
