Mix-ORAM:使用委托洗牌

Mix-ORAM: Using delegate shuffles

Raphael R. Toledo, George Danezis, Isao Echizen

摘要:

不经意RAM(ORAM)是一种在不受信任的机器上提供私有存储和查询的关键技术,但由于客户端重新随机化(称为驱逐)的高开销,通常被视为不切实际。在这项工作中,我们建议安全地将驱逐委托给半信任的第三方,以使任何客户端都能够加入ORAM技术,并以合理的周期成本提出四种不同的设计灵感来自混合网络技术。

英文摘要:

Oblivious RAM (ORAM) is a key technology for providing private storage and querying on untrusted machines but is commonly seen as impractical due to the high overhead of the re-randomization, called the eviction, the client incurs. We propose in this work to securely delegate the eviction to semi-trusted third parties to enable any client to accede the ORAM technology and present four different designs inspired by mix-net technologies with reasonable periodic costs.
