Method for protecting data transmission in an ad hoc network comprising nodes, each node (Ni) comprising a private key (ki), a public key (Ki) and a certificate (Ci) of the public key (Ki) signed by a certification authority (CA). The first node (NA) transmits to the second node (NB) : • a first message (M1) signed (M1/kA) with the private key of the first node (NA); • a third message (M3) containing a first set (ENS1) of initialisation data comprising: - a first certificate including the public key (KA) of the first node (NA), signed by the certification authority (CA), designated KA/kCA; - a second data set (ENS2) comprising: · the IP address (IPA) of the first node (NA); · and the first certificate associated with the IP address (IPA) of the first node (NA), wherein the second data set (ENS2/kA) is signed with the private key (kA) of the first node (NA). |
