Secure Homomorphic Aggregation Algorithm of Mixed Operations in Wireless Sensor Networks

摘要

Wireless sensor networks are employed in a wide range of applications, and its important position is promoted rapidly. Secure data aggregation is one of important technologies in wireless sensor networks. Here we explore a homomorphic aggregation system based on a public key encryption (PKE) scheme, which can do both additive and multiplicative aggregation as well as mixed the two operations. By far, it is the first one that can achieve mixed operations homomorphic aggregation based on PKE scheme. Then we propose a forward secure homomorphic scheme for mixed operations and give its proofs.
