     The second solution uses Merkle trees and minimizes the cost of route protection by the agent owner, so that a single digital signature suffices to protect the whole route; for hosts along the route, the verification cost is similar to the cost of previous schemes in the literature, namely one digital signature verification per route step.

     Merkle trees have found many uses in theoretical cryptographic constructions, having been specifically designed so that a leaf value can be verified with respect to a publicly known root value and the authentication data of the leaf.
