Malicious users and DoS (ongoing...)
Misleading/malicious advertisement
- Source validation at storage nodes
- orthogonal mechanism ensures association between advertisement and principal of trust
Denial of Service attacks
- Overload of infrastructure nodes
- Routing and storage load distribution via node replication
- DoS source identification
- Probabilistic source packet stamping (Savage et. al.)
Invalidation propagation
- Invalidations can be given by authoritative servers
- Can propagate as datagram to referrers
