1. A computer system, comprising: a processor; and a storage device storing instructions that when executed by the processor cause the processor to perform a method, the method comprising: generating, by a first computing device, an interest message which includes a name and a verification token which is a hash of a nonce, wherein a name is a hierarchically structured variable length identifier that includes contiguous name components; in response to transmitting the interest message to a second computing device, receiving a content object message which includes a same name as the name for the interest message; in response to detecting a condition associated with the content object message, generating a content object return message which includes the nonce and a same name as the name for the content object message; and forwarding the content object return message to the second computing device, thereby facilitating the second computing device to process the content object.
