摘　　要：数据卸载是指为了减轻用户设备的存储和处理压力,提高数据处理效率,从而将数据从一台用户设备或终端传输到另一台用户设备或服务器上进行处理和分析的过程。然而,在数据卸载的过程中,大部分研究都集中在最优卸载上,而忽略了数据在卸载过程中的安全性问题。针对这一问题,提出了一种基于最低有效位(LSB)隐写的安全数据卸载方法。使用LSB隐写技术将数据嵌入到数字图像中,并通过传输包含密文的数字图像来隐蔽地将卸载的数据传输到另一个用户设备或服务器。实验表明,使用LSB隐写进行数据卸载与传统卸载方法相比,其所消耗的时间和能量差距会随着用户设备处理器频率的增加而逐渐降低。Data offloading refers to the process of transferring data from one user device or terminal to another user device or server for processing and analysis in order to reduce storage and processing pressure on user devices and improve data processing effi‐ciency.However,in the process of data unloading,most of the research focuses on the optimal unloading,but neglects the security of data during the unloading process.To solve this problem,this paper proposes a method of secure data unloading based on Least Sig‐nificant Bit(LSB)steganography.In this paper,LSB steganography is used to embed data into a digital image and transfer the offloaded data covertly to another user device or server by transmitting a digital image containing ciphertext.Finally,the feasibility and safety of the proposed method are analyzed through simulation experiments.
