Attribute-based Certificateless Aggregation Signcryption Scheme

The advanced measurement system is a complete network that measures, counts, stores, analyzes and uses the user's power information. In the system, smart meters need to send the user's power data to the control center in real time, and the data security and transmission efficiency are extremely high during the transmission process. Therefore, in order to ensure the safe and fast transmission of data, this paper studies the protection methods of user identity and electricity data in the system: aiming at the huge workload problem caused by the correctness of the ciphertext in turn before the control center designs, an attribute-based certificateless aggregation sign-off scheme is proposed, and the security verification in the data transmission process is passed,and the amount of calculation in the transmission process is reduced and the transmission efficiency is improved.
