不经意并行RAM(OPRAM)是由波义耳、Chung和Pass首先提出的,是不经意RAM(ORAM)的自然并行扩展。OPRAM提供了一个强大的加密构建块,用于隐藏程序对敏感数据的访问模式,同时保留原始程序中固有的加密。所有先前的OPRAM方案都采用表征并行运行时中的爆破的“模拟开销”的单个度量,假设不经意的模拟被约束为使用与原始PRAM相同数量的CPU。
Oblivious Parallel RAM (OPRAM), first proposed by Boyle, Chung, and Pass, is the natural parallel extension of Oblivious RAM (ORAM). OPRAM provides a powerful cryptographic building block for hiding the access patterns of programs to sensitive data, while preserving the paralellism inherent in the original program. All prior OPRAM schemes adopt a single metric of “simulation overhead” that characterizes the blowup in parallel runtime, assuming that oblivious simulation is constrained to using the same number of CPUs as the original PRAM.
