Secure Data Transmission of Smart Home Networks Based on Information Hiding

Abstract

Smart home is an emerging form of the Internet of things (IoT), which can enable people to master the conditions of their smart homes remotely. However, privacy leaking in smart home network is neglected. Therefore, it is strongly necessary to design a secure and effective scheme to ensure the privacy protection of the smart home network. Considering the privacy leaking in the smart home network system, this paper proposes a scheme combining encryption and information hiding to ensure the security of data transmission. In the scheme, the sensitive data are encrypted to ciphertext before it is transmitted, and then the ciphertext is embedded into the Least Significant Bit (LSB) of the cover image. On the receiving terminal, the ciphertext can be extracted from the stego image, then the ciphertext is decrypted into the sensitive data. Comparing to the method of using encryption algorithm merely, the scheme greatly improved the security of data transmission, making it more suitable for the real environment.
