论文摘要
本文提出了秘密域（DCCD）中数据计算的想法。我们显示，通过隐藏一些数据计算任务的信息，可以在封面下执行图像，音频，随机数据等。在提议的框架中，发件人将他的源数据隐藏在两个封面中，并将其上传到服务器上。服务器在Stego内执行计算，并将秘密计算结果返回到接收方。通过秘密结果，接收器可以提取源数据的计算结果。在此过程中，服务器和对手在封面中隐藏的源数据是无法察觉的。可以通过公共渠道进行传输。同时，由于计算在秘密域中实现，因此云无法获得计算结果的知识。因此，提出的想法对于云计算很有用。
This paper proposes an idea of data computing in the covert domain (DCCD). We show that with information hiding some data computing tasks can be executed beneath the covers like images, audios, random data, etc. In the proposed framework, a sender hides his source data into two covers and uploads them onto a server. The server executes computation within the stego and returns the covert computing result to a receiver. With the covert result, the receiver can extract the computing result of the source data. During the process, it is imperceptible for the server and the adversaries to obtain the source data as they are hidden in the cover. The transmission can be done over public channels. Meanwhile, since the computation is realized in the covert domain, the cloud cannot obtain the knowledge of the computing result. Therefore, the proposed idea is useful for cloud computing.
