1. A first waveguide system comprising:

  • a processing system including a processor; and

    a memory that stores executable instructions that, when executed by the processing system, facilitate performance of operations, comprising;

    receiving communications that comprise metadata;

    determining whether the communications comply with an encryption requirement based on the metadata;

    responsive to a determination that the communications do not comply with the encryption requirement, determining an encryption type;

    encrypting the communications based on the encryption type to generate encrypted communications that comply with the encryption requirement, wherein the encrypting the communications comprises accessing an encryption database, wherein the encryption database includes public encryption keys and includes device information indicating a location and a device capability for network devices including the first waveguide system and a second waveguide system; and

    transmitting electromagnetic waves to a physical interface of a transmission medium,wherein the electromagnetic waves are directed to the second waveguide system coupled to the transmission medium,wherein the electromagnetic waves propagate without requiring an electrical return path,wherein the electromagnetic waves are guided by the transmission medium, andwherein the electromagnetic waves convey the encrypted communications.
