Abstract
One embodiment of the present invention provides a system for mitigating interest flooding attacks in content-centric networks (CCNs). During operation, the system receives, at a physical interface of a router, an interest packet; obtains current interest satisfaction statistics associated with the physical interface; and determines whether to forward or drop the interest packet based on the current interest satisfaction statistics.
Claims22
A method for mitigating interest flooding attacks in content-centric networks (CCNs), comprising:
- receiving, at a physical interface of a router, an interest packet;
- obtaining current interest satisfaction statistics associated with the physical interface;
- and
- determining whether to forward or drop the interest packet based on the current interest satisfaction statistics.
A non-transitory computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for mitigating interest flooding attacks in content-centric networks (CCNs), the method comprising:
- receiving, at a physical interface of a router, an interest packet;
- obtaining current interest satisfaction statistics associated with the physical interface;
- and
- determining whether to forward or drop the interest packet based on the current interest satisfaction statistics.
A router in a content-centric network (CCN) for mitigating interest flooding attacks, comprising:
- a physical interface for receiving an interest packet;
- an interest satisfaction statistics calculator configured to calculate current interest satisfaction statistics associated with the physical interface;
- and
- a determination mechanism configured to determine whether to forward or drop the interest packet based on the current interest satisfaction statistics.
