What does KSA stand for?

| Type | Initialism |
The initialism KSA stands for Key Source Authority in RFC 9152’s Secure Object Delivery Protocol profile. In its example environment, the KSA generates and protects keys, while a Key Distribution Authority, KDA, distributes the resulting protected package.
Separate responsibility for creating an object from responsibility for delivering it. The profile’s example assigns delegation to a Key Trust Anchor, KTA, key generation and protection to a KSA, and distribution to a KDA. A fictional ledger entry saying package prepared by KSA is therefore not the same event as package delivered by KDA. If no delivery entry is supplied, the preparation label alone does not establish that a client received anything. Likewise, a component’s role label is not proof that a particular operation succeeded or that its certificates should be trusted. The exercise below reads invented responsibility and event fields. It does not generate, sign, encrypt or distribute a key; it checks no certificate and contacts no service. The naming is specific to the cited profile’s described environment, rather than a claim that every system uses these roles or delegates authority in the same way.
Meaning in context
- Key Source Authority
- The KSA role named in the cited profile’s example environment.
- Source and distribution roles
- The profile separates the KSA-created and protected key material from the KDA distribution role.
Practical examples
Do not rename preparation as delivery
- Before
Invented ledger: prepared by KSA; client delivery not recorded. Draft: The client received the package.
- After
The fictional ledger identifies preparation by KSA and supplies no client-delivery event.
Source and delivery records describe different responsibilities and events.
Preserve the recorded role
- Before
Invented responsibility table: KSA = generation and protection; KDA = distribution. Draft: KDA is the source-generation label.
- After
In the fictional table, KSA is the generation/protection role and KDA is the distribution role.
The correction follows the explicitly supplied table and does not validate a real system’s delegation or trust configuration.

Read a key-package responsibility record
Which role and event does this supplied key-package ledger actually identify?
See all guidance
Read a source role
Name the role assigned to creation and protection in the supplied profile.
KSA is the profile’s Key Source Authority.
Read a delivery event
Require a separate delivery record before saying a client received a package.
The fictional ledger supplies preparation and no delivery event.
Read a trust label
Keep a role description separate from actual certificate validation.
The component is labelled KTA; no trust-validation result is supplied.
Keep delegation, key creation and package distribution separate when reading the profile’s KSA, KTA and KDA labels.
