当某些节点没有响应时,我们考虑了在编码数据上设计PIR方案的问题。我们提供了ν稳健的PIR方案的构造,该方案可以容忍高达ν无响应的节点。这些方案是自适应的,并且在为直到ν的任意数量的无响应节点实现(渐近)最优下载成本的意义上是全局最优的。
We consider the problem of designing PIR scheme on coded data when certain nodes are unresponsive. We provide the construction of ν-robust PIR schemes that can tolerate up to ν unresponsive nodes. These schemes are adaptive and universally optimal in the sense of achieving (asymptotically) optimal download cost for any number of unresponsive nodes up to ν.
