Capability Computing

Capabilities are a way of expressing security, which are claimed to work better than the ubiquitous AccessControlLists (ACLs). The basic idea is reminiscent of the LawOfDemeter: you can speak only to objects you have created, or objects that you were created holding, or objects which have been passed to you.

See at the ErosOs web site for a introduction to the notion of capabilities. See for capability computing as it is implemented in E (the EeLanguage).
See CapabilitySecurityModel, ObjectCapabilityModel, CapabilityOrientedProgramming.
