Abstract Abstract
This specification will describe how ephemeral LISP EIDs can be used This specification will describe how ephemeral LISP EIDs can be used
to create source anonymity. The idea makes use of frequently to create source anonymity. The idea makes use of frequently
changing EIDs much like how a credit-card system uses a different changing EIDs much like how a credit-card system uses a different
