A privacy protection policy combined with privacy homomorphism in the Internet of Things

Recently, IOT (Internet of Things) develops very rapidly. However, the personal privacy protection is one of directly important factors that impact the large-scale applications of IOT. To solve this problem, this paper proposes a privacy protection policy based on privacy homomorphism. It can protect the security of personal information well by processing the needs of users without acquiring of plaintext. In another aspect, it also greatly improves the performance of the original multiplication homomorphism algorithm.
