大多数现有的移动的社交系统都建立在通信基础设施的存在上，从而依赖于底层通信基础设施的可靠性。因此，如果用户无法访问基础设施，则无法传输这些系统中用户生成的数据。此外，现有的移动的社交系统具有数据所有者可以在她/他发送数据之前确定目的地的强假设。当底层通信基础设施受到损害时，这是不切实际的。该问题由于系统中存在对手的事实而进一步恶化，其中对手可能试图提取所传输的数据的内容并停止数据传输。因此，这些系统的功能和安全性无法得到保证。在本文中，我们提出了一个安全和高效的数据广播计划的移动的社交网络，使数据所有者广播大规模的数据存储转发的方式，这不需要可靠的通信基础设施。即使数据所有者不能预先确定所有目的地，数据所有者也可以在数据接收器的帮助下尽快将数据发送到所有目的地。我们的方案保证了数据传输不会被对手阻止，并且诚实的用户不会比对手晚提取数据。在我们的方案中，如果对手试图学习数据内容，他必须协助数据所有者传输数据。我们提供了安全性分析来证明我们的方案的安全性。我们还实现了我们的方案，并进行了全面的性能分析，这证明了我们的方案是有效的和高效的。
Most of existing mobile social systems are built on the presence of communication infrastructures and thereby rely on the reliability of the underlying communication infrastructures. As a consequence, if the infrastructures are inaccessible to users, the data generated by users in these systems cannot be transmitted. Furthermore, existing mobile social systems bear a strong assumption that a data owner can determine the destinations before she/he transmits the data. This is not practical when the underlying communication infrastructures are compromised. This problem is further exacerbated by the fact that there are adversaries in the systems, where adversaries may attempt to extract the content of transmitted data and stop the data transmission. As such, the functionality and security of these systems cannot be guaranteed. In this paper, we propose a secure and efficient data broadcasting scheme for mobile social networks that enable data owners to broadcast large-size data in a store-and-forward way, which does not require reliable communication infrastructures. Even if the data owner cannot pre-determine the all destinations, the data owner can transmit the data to all destinations as soon as possible with the aid of data receivers. Our scheme ensures that the data transmission cannot be stopped by adversaries, and the honest user would extract the data no later than adversaries. In our scheme, if the adversary attempts to learn the data content, he has to assist the data owner in transmitting the data. We provide the security analysis to demonstrate the security of our scheme. We also implement our scheme and conduct a comprehensive performance analysis, which proves that our scheme is effective and efficient.
