ACORN: providing network-level security in P2P overlay architectures

摘要

To address the problem of providing network-based security to mitigate and detect cheating in peer-to-peer (P2P) gaming architecture, an architecture suite called architectures with coordinator obfuscation for resilient P2P gaming networks (ACORN) is presented that uses a combination of low overhead, per-packet access authentication, moving-coordinator and cheat detection mechanisms to effectively mitigate security threats.

主权项

1. A method for providing network-based security in a network including a coordinator access point (CAP), a set of candidate coordinator nodes and a plurality of clients, the method comprising:
moving a coordinator functionality between members of the set of candidate coordinator nodes without notifying the clients, wherein the coordinator functionality is scheduled to be moved between members of the set of candidate coordinator nodes periodically, each of the candidate coordinator nodes capable of hosting a coordinator functionality, the coordinator functionality adapted for handling messages associated with the clients; and wherein the coordinator access point (CAP) enables communication between clients and coordinator nodes and dynamically implements network security measures including acting as a trusted intermediary between clients and coordinator nodes.
