Fast batch switching authentication method for predictability and aggregation promise proof
PendingCN119628836Areduce calculationReduce communication overheadKey distribution for secure communicationPublic key for secure communicationHash functionTimestamp
The invention discloses a rapid batch switching authentication method for predictability and aggregation promise proof, which realizes batch authentication of a plurality of user terminals by generating system parameters and secret keys through a trust mechanism and combining predictability promise and aggregation signature technologies. In the authentication process, the edge base station to be switched exchanges with the current communication edge base station through an encrypted message, verification information such as a pre-authentication certificate and a signature is generated through the user terminal, and identity authentication is completed step by step. The method comprises the following specific steps: a trust mechanism generates a private key, a public key, a pseudo identity and an expiration timestamp for each device; through multiple rounds of message exchange, the edge base station and the user terminal perform identity verification by using a shared key and a hash function; and finally carrying out efficient verification on a plurality of users through batch signature and aggregation commitment. According to the method, on the basis of ensuring the security, the speed of switching the authentication process is greatly improved, and the method is suitable for a large-scale network environment, especially in edge computing and mobile communication networks.

Self-destruction control method and system for tethered airship
PendingCN119590601Aavoid threatsprevent leakageLighter-than-air aircraftElectrical batteryGas pressure transducer
The invention relates to a tethered airship self-destruction control method which specifically comprises an airborne control core and a self-destruction standby system so as to ensure that a self-destruction task can be effectively executed under different fault conditions. The airborne control core judges whether the airship exceeds a safety range or not through the GPS module, or receives a remote self-destruction instruction through the wireless communication module to trigger a self-destruction program. The self-destruction process comprises the steps that the valve push rod driving circuit rapidly deflates, the electric heating wire driving circuit burns through the ball body, the lithium battery burning explosion trigger circuit triggers battery burning explosion, and thorough damage is ensured. If the main system fails, the standby control module supplies power through a standby battery, takes over a self-destruction task, keeps communication with the ground, and triggers the parachute to release by utilizing a time delay mechanism or an air pressure sensor when the height sensor fails, so that the landing safety is guaranteed. And the main control program performs byte-by-byte deletion through a bootloader program in a self-destruction process, so that data leakage is prevented.
