An api (Application Programming Interface) provides a library of methods for a service which are linked via a build of an application or service that includes the calling components and the API library. This tightly binds the client to the service. In contrast to protocols, APIs tend to be simple to use.

version 2, commit 7ac6e10, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

authenticity (of an identity) is verifiable traceability to the service that produced the identity. In SSI, that is achieved by cryptographic signing of a hash (e.g., of a message) related to the identity by the identity creation service

version 6, commit dfca235, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

An autonomic process, service or component is one that is autonomous and can operate without supervision but can be re-configured or overridden by an authorized 3rd party.

confidentiality control of access to sensitive personal information.

version 4, commit 83e5f79, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

version 2, commit a7f8ee8, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

decentralized - TBD

version 2, commit 1862336, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

hour-glass model - TBD

Requirements - describe how a protocol stack benefits from an hour-glass characteristic. Should be discussed in terms of emulating the TCP/IP stack and why. Lots of opportunities to specify an outside reference with possibly a summary statement

version 3, commit 3cc68c7, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

identifier vs identity

• An identifier is a Unique ID (UID), which is necessary for machine/machine trust (e.g., required to establish DIDComm channels between entities).
• The identity (of a person or thing) is established via exchanging one or more credentials ((verifiable credential (VCs)) with another party

version 4, commit 14d91a5, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

integrity vs authenticity - Integrity is a subset of authenticity. Authenticity (of a message in SSI) is established via a signature (a cryptographic hash using the private keys of the identifier), which provides integrity. The side effect is you also get non-repudiable authenticity.

version 2, commit 3a3454d, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

interfaces within the ToIP Stack between components include apis and protocols

version 4, commit 88d5bc2, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

intermediary - an intermediary is any system or service at any layer in the ToIP Reference Architecture, which provides additional or supplemental services which may or may not be built using SSI principles

version 2, commit 6b83ef7, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

A Party or Actor has "locus of control" over an identifier (or other SSI component) if they fully control its operations and portability

version 3, commit 6dc7455, created 2022-07-21, last modified 2022-07-21, contributors Neil Thomson

non-repudiable identifier - definition required.

version 2, commit 8c63d68, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

non-repudiation - ToIP Ref Arch level definition required

version 5, commit 20c96cf, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

party - a Party (person, organization, non-human Actor) controls an Actor (software component) to perform Actions on the Party's behalf

version 3, commit 453c760, created 2022-07-11, last modified 2022-07-21, contributors Neil Thomson

privacy

• Protection of personally sensitive data
• Freedom from interference and unauthorized observation (surveillance)

version 2, commit e2fa329, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

protocol - for the purposes of ToIP/SSI protocols, is an interface across a public or private network (in contrast to within a network node)

version 2, commit 44e45c6, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

pseudonymous - a name, term or descriptor (for an entity: person or thing) that is different from their actual name

pseudonymous identifier - an identifier used (primarily for machine trust) that is not the same as the entity's actual name. A phone number is a pseudonymous identifier

version 2, commit c0243a3, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

service - a software component providing (typically) a single feature or tightly related features via an api

version 2, commit e42dd64, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

version 2, commit cca68ec, created 2022-07-11, last modified 2022-07-11, contributors Neil Thomson

verifiability - to be able to verify an assertion claim (e.g., ownership of an identifier, that a verifiable credential was issued by a registered issuer)

verifiable non-repudiation - is a strong form of verification. Where the act of verification confirms non-repudiation.
