Fuzzy IBE ⇒ IBE

Fuzzy IBE implies IBE.

Statement

Migrated verbatim from fuzzy-identity-based-encryption § Fuzzy identity-based encryption:

Fuzzy identity-based encryption (Fuzzy IBE) is an extension of IBE in which identities are represented as sets of descriptive attributes drawn from a universe $\mathcal{U}$.

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

• Fuzzy IBE generalizes IBE: setting $t=1$ and $|\omega |=|{\omega }^{\prime }|=1$ recovers exact-identity matching

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

• IBE is generalized by Fuzzy IBE, which allows partial identity matching via a threshold overlap condition

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.
• Duplicates the ‘Other results’ bullet at line 79 of the same page.
• ‘is an extension of’ reverses the arrow relative to the word order (FIBE ⇒ IBE).
• No citation and no folklore flag.
• Duplicates the intro sentence at line 13.
• No citation (SW05 fuzzy IBE).
