E-DHCP: extended dynamic host configuration protocol

This paper proposes an extension to DHCP protocol, called E-DHCP (extended-dynamic host configuration protocol). This protocol is based on two principles. The first is the definition of a new DHCP option (RFC 2489) that provides simultaneously the authentication of entities and the authentication of DHCP message. The technique used by this option is based mainly on the use of asymmetric public keys encryption RSA, X.509 identity certificates and attribute certificates. The second is the attribution to DHCP server the functionalities of the AA (attribute authority) server of a PMI (privilege management infrastructure).
