Paper:
Secure Login Across Networks

Abstract:

Login across networks presents a security problem in that passwords may be captured by eavesdroppers. This is a worsening problem for AARNET users as the number of nodes and users grows. Various techniques are available to foil eavesdroppers.

This paper reviews some commercial proprietary devices and some non-proprietary systems, including Kerberos and skey. Challenge-response systems, with symmetric keys or with public keys, are being researched at QUT and will be discussed.
