Claim Text:
1. A method of establishing secure discovery and secure communication in an ad hoc information-centric network (ICN), comprising: an application in a consumer device sending a discovery interest including an associated service name or prefix signed by an encryption key using the ICN; a producer device publishing and discovery protocol (SPDP) on an ICN stack of a producer device receiving the discovery interest from the ICN and checking to see if there is a local published service that matches the service name or prefix in the discovery interest, and if so, verifying the consumer device using the encryption key; the producer device SPDP returning a data protocol data unit (PDU) to the consumer device configured to enable the consumer device to access the local published service; and the consumer device establishing routing with the producer device and receiving the local published service; wherein the data PDU includes a random name, a service profile, and a public key, the random name corresponding to the service name or prefix; wherein all intermediate nodes between the consumer device and the producer device forwarding the discovery interest and the PDU are unaware of the service name or prefix.
