A safe distribution scheme of sensitive data based on full homomorphic encryption model

Given the problems of a large number of nodes, the huge demand for IP addresses and the poor security of communication between nodes in IPv6 wireless sensor networks, this paper proposes a homomorphic data encryption scheme based on the SSL protocol in IPv6 network. The proposed scheme is mainly to realise the secure distribution of secret file information between the server and the corresponding network nodes. Besides, in response to the security problems of the confidential file distribution system, this paper also proposes a new SSL-based security protocol. The proposed protocol can not only securely send and receive confidential files but also limit the client's operation on confidential files. Furthermore, the protocol uses an improved fully homomorphic encryption algorithm to operate on the ciphertext. The algorithm improves the efficiency and security of transmission between nodes by reducing the size and expanding the plaintext space. Experimental results and comparisons show that the proposed scheme has the advantages of better security and availability during data transmission than other schemes.
