SLIDE 2

Historic IP View of Communication

Resource, e.g. Printer Computation

Run the Physics Simulation on the Cray

OK, Result

SLIDE 3

Content Delivery Networks

Communication is data oriented
Data is “in” the network
No one host holds the data
Caching, e.g. Squid
Strategic placement, e.g. Akamai

Basic Communication Elements

Communication Infrastructure

Security in CCN

With IP, you think about securing the connection
With CCN you just secure the data
Content packet is always signed (integrity)
Requester and/or infrastructure can verify the

signature

Key distribution?
Could chose to only look at data signed by

particular entities. Or signed by signed by particular entities.

SLIDE 9

Confidentiality in CCN

Applications can chose to encrypt the payload
Again key management responsibility of higher

layers.

SLIDE 10

Availability in CNN

Interest requests are merged
There is no way a client can directly probe a

server.

SLIDE 11

Attacking the infrastucture?

Could you put up a Content router that doesn't

play by the rules?

Could you insert yourself in the middle of a

CCN network?

If you could “own” a CCN element, would you
