1. A verification computing device for geo-location attestation of computing devices in a network path, the verification computing device comprising:

  • a secure trace packet generation module to generate a secure trace packet, wherein the secure trace packet includes a timestamp corresponding to a departure time of the secure trace packet from the validating computing device;

    a communication module to transmit the security trace packet to a computing device in the network path, wherein the network path identifies one or more intermediary computing devices through which the security trace packet is transmitted from the verifying computing device to a target computing device;

    a cryptographic module for verifying a signature of a cryptographically signed security tracking packet received by the verification computing device from the computing device; and

    a network path authorization module to determine whether a sub-path of the network path is authorized based on reference network path data and the cryptographically signed security tracking packet, wherein the reference network path data indicates a maximum geographical distance allowed between two computing devices in the network path, and wherein the verifying computing device authorizes subsequent computing devices in stages or sub-flows such that each of the intermediate computing devices is re-evaluated in determining whether a particular computing device is authorized.
