With the application of Internet of things technology, smart home is gradually changing people's lifestyle. However, IoT devices are vulnerable to attacks that leak user privacy, it leads to some security issues. In this paper, a BFP authentication scheme combining fog computing and blockchain technology is proposed, and the Paillier encryption algorithm is used to generate the key, which ensures the security and privacy of data. Finally, we compare the encryption and decryption efficiency of Paillier and RSA encryption algorithms, and evaluate and analyze them from several aspects. The results show that the proposed scheme has superior performance in terms of security, and the computational overheads of key execution is less than the traditional scheme. Under the premise of ensuring data security, the proposed scheme can effectively improve the execution efficiency of IoT devices.
