Dieser Lightning Talk wurde in der [[KunterBuntesSeminar-WS11/Lightning Talks 2|zweiten Lightning Talk Session]] des KunterBuntenSeminars im Wintersemester 2011 gehalten.

== Monkeysphere ==

In diesem Vortrag wurde Monkeysphere vorgestellt.

=== Folien als Text ===
==== What is a monkeysphere? ====

* Sorry it is not about animals like you might think
* It is about us, living in a monkeysphere
* It is about identifying someone as person
* It is about your peers living in a monkeysphere
* It is about authentication, as we need it for authorization andconfidentiality

==== Trust relationships ====
Whom should we trust?

* Should we trust some certificate authorities?
* We do not know how they certificate some service
* We even do not know them, do we?
* Why not trust the people we already know and have relationship to?

====adding services to the web of trust ====
What we have is the Web of trust, that reflects trust relationships
transitively.

* People we know sign services like ssh, https
* We use a service:
* monkeysphere gets the keys
* monkeysphere checks trust relations
* monkeysphere grants us access to a service, if we do trust if we do not trust monkeysphere provides us with the old way

==== Extending the web of trust ====

How does this work then?
* create pgp-key with service-protocol and fqdn as uid
* sign the pgp-key
* export the pgp-key to the web of trust
* let others sign the key

What do we get out of this?

* trusting people we know to authenticate a service to us
* getting around calling server administrators asking for fingerprints

==== This is how we create a key: ====

monkeysphere−host import−key / etc / ssh / ssh_host_r sa_key ssh : // b j o e r n . e x a m p l e . o r g

That is what a key looks like:

bjoern : / etc / ssh# monkeysphere−host show−key
pub
2048 R / EF569B13 2012−01−22
uid
ssh : // b j o e r n . e x a m p l e . o r g
OpenPGP fingerprint : 2 B 4 1 5 2 5 D 5 2 E 6 1 8 8 B A 8 3 6 B 2 B 7 7 D C 7 E F 2 1 E F 5 6 9 B 1 3
ssh fingerprint : 2048 6 7 : cf : a1 : 7 3 : 8 9 : d2 : 5 2 : a8 : 7 7 : 9 0 : 9 8 : 1 f : f6 : 6 b : f0 : dc ( RSA )
