Nouns
7 senses- Masquerading
When an unauthorized agent claims the identity of another agent, it is said to be masquerading.
- Mobile Software Agent
Programs that are goal-directed and capable of suspending their execution on one platform and moving to another platform where they resume execution.
- Multi-Hop Problem
The security risks resulting from a mobile software agent visiting several platforms.
- Path Histories
Maintaining an authenticatable record of the prior platforms visited by a mobile software agent, so that a newly visited platform can determine whether to process the agent and what resource constraints to apply.
- Sandboxing
A method of isolating application modules into distinct fault domains enforced by software. The technique allows untrusted programs written in an unsafe language, such as C, to be executed safely within the single virtual address space of an application. Untrusted machine interpretable code modules are transformed so that all memory accesses are confined to code and data segments within their fault domain. Access to system resources can also be controlled through a unique identifier associated with each domain.
- Single-Hop Problem
The security risks resulting from a mobile software agent moving from its home platform to another platform.
- Software-Based Fault Isolation
A method of isolating application modules into distinct fault domains enforced by software. The technique allows untrusted programs written in an unsafe language, such as C, to be executed safely within the single virtual address space of an application. Untrusted machine interpretable code modules are transformed so that all memory accesses are confined to code and data segments within their fault domain. Access to system resources can also be controlled through a unique identifier associated with each domain.
