The Wi-Fi Direct is a new wireless connection technology based on this demand, which enables Wi-Fi devices to connect easily with each other by the peer to peer mode without requiring a wireless access point. However, when we want to send data to other users’ device for data processing and do not want other users to be able to decrypt the data, the traditional Wi-Fi encryption system will be unable to meet our needs. In view of this, we proposed to use fully homomorphic encryption combined with current Wi-Fi encryption system to solve this problem. The concept of homomorphic encryption is when we carry out a specific operation on ciphertext, after decryption, the result is equivalent to the corresponding plaintext. So that we can perform data processing in ciphertext and maintain the correctness of data, and make the devices to pass and process data through Wi-Fi Direct protocol with convenience and security.
