Attack tree (BGPsec)¶

Undermining BGPsec means going after one of three things: the cryptography that signs each hop, the trust infrastructure that decides whose signature counts, or the long, uneven rollout in between. The last is the softest, since a protocol built to make forgery detectable still leaves plenty forgeable while most networks have yet to switch it on.
