  The client-server model is known to scale badly without redundant servers and
caches. Information-Centric Networks (ICN) are an alternative designed to
lessen that problem by distributing load to intermediary routers, lowering the
bar to techniques only accessible to server farms. However, this seamlessness
comes with its own set of problems. Communication security, by using a key per
connection, prevents intermediaries from reading and thus caching content. We
thus need to share a common key for larger groups of correspondents to be able
to benefit from the advantages of ICN. This paper presents the algorithmic
choices to establish such a group key, the adaptations made for ICN, its
implementation, and the statistics backing its performances comparison with our
baseline. The first results tend to show a performance improvement over the
selected base algorithm.
