摘要: PRESTO, Japan Science and Technology CorporationABSTRACTExecutable content poses a threat of unauthorized accessbecause it contains program code running on the user’smachine. Protecting against executable is difficultbecause inevitable flaws in implementation ofprotection mechanisms. This paper introduces hierarchi-cal protection model to tolerate mecha-nisms. improves both granularity therobustness mechanisms by nesting two pro-tection domains: level-1 domainto providefine-grained access control content, alevel-2 act as fail-safe mechanism.We achievedan efficient hierarchicalprotection that incorporated fine-grained protec-tion domains proposed our previous paper.KEY WORDSExecutable Content, Security, Operating System, Fine-grained Protection Domain
