KE ⇒ Multi-party key exchange
KE implies Multi-party key exchange.
Statement
Migrated verbatim from key-exchange § Multi-party key exchange:
Generalizes two-party KE to parties. Requires additional rounds or structure (e.g., Burmester-Desmedt, pairing-based constructions).
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.
Recorded during migration and not fixed — these are claims about the source text, not changes to it:
- Vague: ‘Requires additional rounds or structure’ asserts a cost, not a reduction.
- Burmester-Desmedt and ‘pairing-based constructions’ (Joux) are named in prose with no reference pages and no citations.
