Abstract
This paper proposes a generic security architecture
designed for a multidomain and multiservice network
based on programmable networks. The multiservice
network allows users of an IP network to run
programmable services using programmable nodes
located in the architecture of the network. The
programmable nodes execute codes to process active
packets, which can carry user data and control
information. The multiservice network model defined
here considers the more pragmatic trends in
programmable networks. In this scenario, new security
risks that do not appear in traditional IP networks become
visible. These new risks are as a result of the execution of
code in the programmable nodes and the processing of the
active packets. The proposed security architecture is based
on symmetric cryptography in the critical process,
combined with an efficient manner of distributing the
symmetric keys. Another important contribution has been
to scale the security architecture to a multidomain
scenario in a single and efficient way.
