[en] Structured P2P networks have proven to be effective in the
exchange of data between nodes whose identity and content are generally
indexed in a DHT. For years, such DHT networks have allowed, among
other users, third world inhabitants, such as African people, to exchange
information among them and with the rest of the world without relying
on a centralized infrastructure. Unfortunately, more than ever, reliability
of communication across the Internet is threatened by various attacks,
including usurpation of identity, eavesdropping or traffic modification.
Thus, in order to overcome these security issues and allow peers to securely exchange data, we propose a new key management scheme that
enables to handle public keys in the absence of a central coordination
which would be required in a traditional PKI.
