This is a P4 implementation of an anonymity router for the PHI protocol [2] on Intel Tofino programmable switch. For more details, please refer to our paper: "Feasibility of Network-layer Anonymity Protocols at Terabit Speeds using a Programmable Switch," (to appear in IEEE NetSoft 22).
The part of this program calculating HalfSipHash is created with reference to the implementation of Yoo et al. [3]
