Bounding Corruptions in the Graded-PKI Model Sample Clauses

Bounding Corruptions in the Graded-PKI Model. In the standard model, it is customary to bound the number of parties corrupted by the ad- versary. This works in the full PKI model as well, since every public key is associated with a single party. In the graded PKI model, however, the adversary can create many different keys without corrupting additional parties. Moreover, for player-replaceable protocols, the honest-majority requirement must hold sep- arately for each committee. Thus, we need to modify the notion of an honest majority to take this into account. S }
