This document describes the Secure Asset Exchange Protocol (SAEP). SAEP is a protocol operating between two gateways that coordinate the atomic exchange of digital assets in two different asset networks.¶

The following are some terminology used in the current document. We borrow terminology from [NIST] and [ISO] as much as possible, introducing new terms only when needed:¶
Asset network (system): The network or system where a digital asset is utilized.¶
Secure Asset Transfer Protocol (SATP): The protocol used to transfer (move) a digital asset from one network to another using gateways.¶
Origin network: The current network where the digital asset is located.¶
Destination network: The network to which a digital asset is to be transferred.¶
Data sharing: The process, using the Asset Transfer Protocol, by which one or more units of verifiably authentic data are communicated from an Origin network to a Destination network, either voluntarily or upon request.¶
Asset Transfer: A fail-safe process of moving an asset from one network to another, with the destruction of the asset in the Origin network and its recreation in the Destination network occurring as a single atomic action.¶
Asset Exchange: A fail-safe process of exchanging (or swapping) assets held by a pair of owners, each asset being maintained in a different network, with the two in-network transfers occurring as a single atomic action.¶
TBD: List security considerations, if any.¶
TBD: Does this document require any IANA actions?¶
