Key Authentication
- normally not found in symmetric key cryptography
- channel to transmit key should be secure
- Kerberos
- a network authentication protocol
- ensures that both the client and the server are authenticated
- developed for symmetric keys; however, capable of conveying and authenticating asymmetric keys too
- was banned from being exported by the US -- contains DES
- versions
- Heimdal Kerberos -- identical behaviour of Kerberos -- full compatibility, making the ban irrelevant
- Active Directory
- TrustBroker
- ShiShi
- how does it work?
- client sends text to Key Distribution Center
- see notes
