Abstract

Oppfinnelsen sørger for robust, effektiv, fordelt generering av RSA-nøkJer. En effektiv protokoll er en protokoll som er uavhengig av primalitetstest-"kretsstørrelsen", mens en robust protokoll tillater riktig fullførelse selv ved nærvær av en minoritet av tilfeldig dårlig opptredende, ondsinnede deltakere. Den viste protokoll er sikker mot enhver minoritet av ondsinnede deltakere (hvilket er optimalt). Den viste metode er nyttig ved etablering av følsomme, fordelte, kryptografiske funksjonsdelingstjenester (attesteringsmyndigheter, signatursystemer med fordelt tillit, og nøkkelsperringsmyndigheter), så vel som ved andre anvendelser ved siden av RSA (nemlig sammensatt ElGamal, identifikasjonssystemer, samtidig bitutveksling, etc.). Den viste metode kan kombineres med proaktive fiinksjonsdelingsteknikker for å etablere de første effektive, robuste og proaktivt sikre RSA-baserte tjenester med optimal feiltoleranse og fordelt tillit, hvor nøkkelen aldri betros til en eneste entitet (dvs. fordelt tillit helt "fra bunnen av"). Den viste metode innebærer nye, effektive "robusthets- sikkerhetsteknikker" som garanterer "riktige beregninger" ved å ha gjensidig mistillit til deltakere med ondsinnet minoritet.
