Linear secret sharing schemes (LSSS) ⇔ MSP

Linear secret sharing schemes (LSSS) is equivalent to MSP.

Statement

Migrated verbatim from secret-sharing:

A secret sharing scheme is linear if the shares are linear functions of the secret and randomness. Equivalent to monotone span programs over .

Migrated verbatim from secret-sharing § Other results:

  • LSSS is equivalent to monotone span programs, which characterize the class of access structures realizable by linear schemes — standard

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 2 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:

  • Uncited equivalence; duplicates the ’# Other results’ bullet on line 65 (which carries the ’— standard’ folklore label).
  • Neither ‘linear-secret-sharing-scheme’ nor ‘monotone-span-program’ has a page.
  • Uncited, carries the ’— standard’ folklore label; duplicates line 57.
  • Neither object has a page.
  • The second clause (‘which characterize the class of access structures realizable by linear schemes’) is a separate characterization claim bundled in.
