AMI wireless sensor network security data aggregation method, electronic equipment and medium

Abstract

The invention provides an AMI wireless sensor network safety data aggregation method. The method comprises the following steps: selecting big primes number in intelligent electric meter collected data, computing the product of a group of randomly selected prime numbers, and presetting the above data and a homomorphic encryption key; encoding the collected data, and encrypting the encoding plaintext by adopting an homomorphic encryption algorithm; performing modular operation on the collected data and the prime numbers, and encoding the remainder; aggregating the homomorphic ciphertext data andverification labels through an aggregation node; decrypting the aggregation ciphertext by using a data concentrator, summarizing the decrypted collected data to generate a first data sum, and decrypting the aggregated verification label to acquire the second remainder; and generating the second data sum according to the preset prime numbers and the second remainder, and tverifying the first datasum and the second data sum. The invention further relates to electronic equipment and a storage medium. the data transmission amount in a wireless sensor network in the AMI can be effectively reduced, the transmission efficiency is improved, the network service life is prolonged, and the security is strong.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to an AMI wireless sensor network security data aggregation method, electronic equipment and media. Background technique [0002] The advanced measurement system AMI (Advanced Metering Infrastructure) is a key link in the development of the smart grid, and is regarded as the first step in the smart grid. Wireless Sensor Networks (WSNs) is a new wireless communication technology, which has been widely used in smart meters (IM) and other smart devices in AMI. In AMI, a large amount of information is collected and transmitted through WSNs, thereby improving the perception ability and intelligent control ability of the power grid, and providing reliable information support for the development, planning and maintenance of the power grid. [0003] AMI needs to ensure the accuracy of power consumption and supply data to prevent data tampering and electricity theft. However, ...
