Securing the last mile of DNS with CGA-TSIG
Tue, 8 Jan 2014
TSIG with shared keys is not scalable as a solution for the DNS last mile problem. CGA-TSIG extends TSIG with CGA so that
shared secrets are no longer required. This research investigates the CGA-TSIG proposal by doing a security analysis and
by making a PoC implementation in ldns.

Experiences with MPTCP in an International OpenFlow Network
Tue, 3 Sep 2013
Keeping up with the network demand in order to transfer these data sets over the Internet is a challenge. Single links do not have enough capacity anymore. Therefore we need to install more interfaces in the servers and use all available paths in the network. In this paper we describe two new technologies that help to optimally use the capacity of all multiple paths simultaneously: OpenFlow and Multipath TCP (MPTCP).
