Differentially Private ADMM-Based Distributed Discrete Optimal Transport for Resource Allocation. (arXiv:2211.17070v1 [cs.SI])

Optimal transport (OT) is a framework that can guide the design of efficient
resource allocation strategies in a network of multiple sources and targets. To
ease the computational complexity of large-scale transport design, we first
develop a distributed algorithm based on the alternating direction method of
multipliers (ADMM). However, such a distributed algorithm is vulnerable to
sensitive information leakage when an attacker intercepts the transport
decisions communicated between nodes during the distributed ADMM updates. To
this end, we propose a …
