Abstract:
This document describes the NSIS Signaling Layer protocol (NSLP) for
network traffic authorization on the Internet, the Permission-Based
Sending (PBS) NSLP. This NSLP aims to prevent Denial-of-Service
(DoS) attacks and other forms of unauthorized traffic. PBS NSLP is
based on a hybrid approach: a proactive approach of explicitly
granting permissions and a reactive approach of monitoring and
countering attacks. Signaling installs and maintains the permission
state of routers for a data flow. A monitoring mechanism provides a
second line of defense against attacks. PBS NSLP uses two security
mechanisms: message security for protecting the integrity of the
message on end-to-end traffic and channel security for protecting the
integrity and confidentiality between adjacent nodes. To
authenticate data packets, the PBS NSLP requests a sender to use an
existing security protocol, the IPsec Authentication Header (AH).
