To do:

  • Add etymology to introduction [done 2007-01-06T22:38]
    • The name comes from recognition of the fact that "pure" object-oriented programming constitutes the capability-based security model. [done 2007-01-06T22:38]
    • Touted advantages of objects (encapsulation, modularity) are precisely what we want for security (privilege separation, least privilege). [done 2007-01-06T22:38]
  • Section: Advantages of object-capabilities
    • No such thing as ambient authority (explain what that is)
    • Only connectivity begets connectivity
    • Show the Granovetter diagram!
    • No fixed set of operations (read, write, etc.); everything is invocation
    • Section: Combining designation and authority
      • Solving Confused Deputy
  • Section: Relationship to object-oriented programming
    • references are called "pointers"
  • Section: Relationship to capability-based security
    • references are called "capabilities"
    • the term "capability"
    • object-capabilities versus password capabilities
    • explain distinctions as in Capability Myths Demolished
  • Possible section: relationship to lambda calculus?

A few additional topics

  • Synergy (can + can opener => contents)
  • sealers/unsealers
  • factory pattern
  • membrane pattern (probably doesn't belong on front page)
  • other systems to mention:
    • Joule [added 2007-01-06T22:38]
    • KeyKOS [added 2007-01-06T22:38]
    • Coyotos

Concrete example

So far this page is pretty abstract. I think the first subsection after the introduction should give a practical example. — Ka-Ping Yee 23:59, 6 January 2007 (UTC)[reply]
