面向频谱动态分配的算法机制设计

随着无线通信技术的快速发展和新型无线应用的大量涌现,有限的无线电频谱资源变得越来越紧缺。现行的无线电频谱资源管理体制为每种无线通信技术分配了一个固定的频谱段。这种静态分配策略造成本已稀缺的频谱资源不能得到有效的利用,具体体现在两个方面:一方面,静态频谱分配没有充分考虑频谱需求的空间和时间差异性,造成在很多地区,大块的频谱资源长期处于闲置状态;另一方面,新兴的无线网络应用由于缺乏足够的频谱资源而无法发挥其应用价值。所以,为了有效的利用有限的频谱资源,频谱资源动态二次分配变得尤为重要。新兴的认知无线电技术不但使频谱资源动态二次分配成为可能,也将博弈论和计算机科学融合的产物——算法机制设计——的重要性提高到了一个前所未有的高度。

我们借鉴算法机制设计的思想探索频谱资源动态二次分配中的市场规律,研究该问题中的独特挑战性问题,包括投标真实性保障、频谱空间重用性、通信信道异质性、用户需求多样性、计算复杂性、合谋抑制、隐私保护、正确性验证等,并提出了一系列新型频谱动态拍卖机制。相关研究成果发表在多个国际学术会议和学术期刊,如IEEE INFOCOM、ACM MobiHoc、IEEE Transactions on Mobile Computing、IEEE Transactions on Computers、IEEE Transactions on Parallel and Distributed Systems等。

 

安全最近邻查询处理

云计算由于它的灵活性和可扩展性得到日益普及,应用之一就是云计算服务提供商提供云端的数据库访问。数据所有者外包自己的数据库给云服务提供商,并依靠他们提供存储,管理和查询数据库等服务。然而,数据的远程放置也带来安全问题。数据拥有者在使用云服务的同时可能也希望防止数据和查询信息的泄漏。

我们研究了如何在外包环境下进行无信息(包括数据和查询)泄漏的数据查询处理,其中重点研究了最近邻问题。我们首先指出了现有方法的安全漏洞,证明了安全最近邻问题和保序加密(order-preserving encryption)问题一样困难。由于保序加密被证明在标准安全模型下很难构建,因此我们提出了新的解决思路。我们通过对数据进行分块,填充和加密,使得用户可以在只需要取得一块加密数据就可以找出最近邻。这样既保证了安全性,又提高了查询效率。该成果发表在IEEE ICDE 2013。
