A privacy protection method for homomorphic encryption in wireless sensor networks

Abstract

The invention relates to a homomorphic encryption privacy protection method for a wireless sensor network, in particular to ensure the redundancy of data through a linear restoration algorithm and ensure the privacy of data through homomorphic encryption. The linear restoration algorithm is to add hidden fragmented data information to the fragmented data to ensure that even in the case of data packet loss, the hidden data information is used to restore the original data, and the privacy of the data is guaranteed through the homomorphic encryption algorithm. Data privacy protection. At the same time, the combination of homomorphic encryption addition and linear reduction will not increase the amount of calculation too much, which is suitable for the characteristics of weak computing power of wireless sensors.

Description

technical field

[0001] The invention relates to a privacy protection technology scheme applied to wireless sensor networks, aiming at the problem that the privacy protection algorithm based on fragmentation technology is sensitive to packet loss, and specifically guarantees data redundancy and homomorphic encryption through a linear restoration algorithm Data privacy, so as to ensure that the data has the function of restoring packet loss during transmission. The technology belongs to the field of wireless sensor network privacy protection. Background technique
