Abstract
Oblivious keys are a fundamental resource to support secure multiparty computation. Nevertheless, classically it is very resource demanding to generate and to distribute secure oblivious keys, which has been hindered their utilization. However, using quantum communications they can be generated and distributed with an efficiency similar to secret symmetric keys. This can allow the proliferation of applications supported by secure multiparty computation. In this work, we discuss the generation and distribution of oblivious keys in fiber optic networks using quantum communications.
