ABE ⇒ IBE

ABE implies IBE.

Statement

Migrated verbatim from attribute-based-encryption § Attribute-based encryption:

Attribute-based encryption (ABE) generalizes IBE by replacing exact-identity matching with expressive Boolean access policies.

Migrated verbatim from identity-based-encryption § Other results:

• IBE is a special case of both KP-ABE and CP-ABE with singleton policies

Notes

source: folklore: the claim carried no citation on the page it was migrated from, and none was invented.

class: unstated: no citing page says which notion of reduction is meant. Recording a class the wiki does not state would add a claim.

This relation is stated on 3 pages; the statements above are all of them.

Recorded during migration and not fixed — these are claims about the source text, not changes to it:

• No citation.
• Stated as a generalization (‘ABE generalizes IBE’), not as a security reduction; typed here as ABE ⇒ IBE since IBE is the special case. A migration tool must not read the surface word order as the implication direction.
• Bullet packs TWO disjunctive claims (KP-ABE ⇒ IBE and CP-ABE ⇒ IBE); must be split into two reductions, not one conjunctive one.
• Both wikilinks target the same page attribute-based-encryption with different display text, so the two distinct objects are indistinguishable after migration.
• Second of the two disjunctive claims on this bullet (CP-ABE ⇒ IBE).
• Same-page wikilink collision as above; hypothesis object is CP-ABE but the slug cannot distinguish it from KP-ABE.
