Secure Neighbor Discovery implementation for IPv6
SEND is the implementation of RFC3971 Secure Neighbor Discovery SEND. SEND cryptographically secures the IPv6 neighbor discovery protocol, countering the threats discussed in RFC3756 IPv6 Neighbor Discovery ND Trust Models and Threats.
The implementation is a new version of DoCoMo’s SEND send_0.2 that was implemented completely in user space. Novelty in send_0.3 is the native SEND API that avoids the need for the use of netgraph and BPF, which makes send_0.3 portable over different BSD platforms and significantlly more efficient.
Also included in the distribution are implementations of RFC3972 Cryptographically Generated Addresses CGAs and RFC3779 X.509 Extensions for IP Addresses and AS Identifiers.
