....has to be protected where there is a risk of attack or exposure. The technological safeguards which may be relied upon to prevent these risks include both hardware and software controls. However, to what extent should hardware and software be trusted to provide such controls Freisleben et al. [8] state that there is no way to provide security without trusting certain components, services or people involved in the development of a computer system. In his Turing Award Lecture [9] Thompson points out that a user may only trust code which the user personally created. He justified this by ....

....may be modelled as either modules or segments. Modules and segments are identified by their virtual memory addresses which remain constant and are never reused. Thus, capability based addressing [43] is used to protect the module or segment objects. There are two levels of protection in Monads pc [8] one which protects modules, called the module capability ; and the other which protects segments called the segment capability . A module capability identifies the virtual address space for the module. There may be several (module) capabilities for an object (one for each user allowed to use ....
