| <p>The Apache Milagro (Incubating) Decentralized Trust Authority (D-TA) is a collaborative key management server. It has two primary functions.</p> |
| <ol> |
| <li><strong>Issue</strong> shares of identity-based Type-3 pairing secrets for initializing zero-knowledge proof multi-factor authentication (ZKP-MFA) networks of clients and authentication servers.</li> |
| <li><strong>Safeguards</strong> shares of generic secrets, acting independently but in conjunction with other D-TA nodes, for the benefit of other D-TA nodes.</li> |
| </ol> |
| <p>In the use case where it issues shares, the D-TA holds nothing except for its Master Secret and acts as a distributed private key generation server. In the use case where it is safeguarding shares of secrets, it is up to the application developer to implement back-end application logic to hold those shares securely. Examples include using Hardware Security Modules (HSMs) via an on-board PKCS#11 implementation to create a realm of key encryption keys, or multi-party computation through BLS signature aggregation.</p> |

| <p>Operators of Decentralized Trust Authorities are segmented into three roles.</p> |
| <ol> |
| <li><p><strong>Principals</strong> - These entities operate a Milagro D-TA node to securely communicate with other D-TA nodes (Fiduciaries), employing them to issues shares of secrets or safeguard shares of secrets.</p></li> |
| <li><p><strong>Fiduciaries</strong> - These entities operate \( 1 + n \) Milagro D-TAs to issue shares of secrets or safeguard shares of secrets.</p></li> |
| <li><p><strong>Beneficiaries</strong> - These entities receive shares of secrets from Fiduciaries.</p></li> |
| </ol> |
| <p>A D-TA facilitates secure and auditable communication between entities and service providers who can keep shares of secret keys safe (Fiduciaries). The D-TA is written in Go and uses REST services based on the GoKit microservices framework. The D-TA uses IPFS to create a shared immutable log of transactions and relies on Milagro-Crypto-C for it's crypto. Future release candidates will incorporate Tendermint for consensus protocol.</p> |

| <p>In order to safeguard a secret using the D-TA a minimum of two roles are required: a client (Principal) and a server (Fiduciary). In addition a third party can be nominated as the ultimate recipient of the secret (Beneficiary). You can run a single D-TA to provide all three roles if you want to see it in action. See the <a href="/docs/dta-details/quickstart">quick start guide</a> for instructions on how to do that.</p> |
| <p>This system can be imagined like a "network HSM". Below is a VERY simplified overview of the process:</p> |

| <p>The <strong>Seed</strong> is the focus of the system - the D-TA provides a method for Principals to communicate with Fiduciaries who can secure their secrets, it does not prescribe how the securing should be done. The most basic implementation of a D-TA should secure seeds in an HSM using a PKCS#11 interface.</p> |
| <p>We hope that many custodial services will adopt the Milagro D-TA as a communication protocol and that they will bring a profusion of security paradigms, by working together we can make a dynamic market place for custodial services and together make the Internet a safer place.</p> |

| <p>The D-TA provides a secure, distributed method of communication between Beneficiaries, Principals and Fiduciaries. It aims to solve the following problems:</p> |
| <ol> |
| <li><p>How can actors in the system be identified and trusted?</p> |
| <p><strong>Answer:</strong> <a href="/docs/dta-details/identity-documents">Identity Documents</a></p></li> |
| <li><p>How can records of interactions between actors in the system be trusted and verified?</p> |
| <p><strong>Answer:</strong> <a href="/docs/dta-details/encrypted-envelope">Encrypted Envelopes</a> via <a href="/docs/dta-details/ipfs">IPFS</a></p></li> |
| <li><p>How can different custodial services provide their own "special security sauce"?</p> |
| <p><strong>Answer:</strong> <a href="/docs/dta-details/plugins-overview">Plugins</a></p></li> |

Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.</div></section><p></p><section class="copyright">Copyright © 2022 The Apache Software Foundation.
