AI Technical Summary
Existing water conservancy IoT systems lack lightweight, highly secure, and reliable access authentication methods that meet the security needs of different businesses, and device private keys are easily leaked, leading to security threats.
By generating random numbers on the client and server sides, using the device root key and unique identifier in the hardware security module to generate a temporary key pair, performing joint signing and key negotiation, generating a session key, realizing device identity authentication, and only transmitting the hash value of the device identity certificate to reduce the amount of communication data.
It improves key security, reduces the requirements for terminal device performance and network bandwidth, enhances long-term communication security, enables the handling of different business security needs, and ensures the security and resource conservation of critical businesses.
