US 2019/0199540 A1 · ENABLING HTTP CONTENT INTEGRITY FOR CO-INCIDENTAL MULTICAST DELIVERY IN INFORMATION-CENTRIC NETWORKS

Abstract

Employing proxy rule identifiers to ensure the integrity of content delivered over an HTTP-over-ICN system. An exemplary method is performed by a client-side network attachment point (cNAP) on an information-centric network (ICN). The cNAP receives an HTTP request that includes a resource identifier and at least one header field. The cNAP generates a proxy rule identifier (PRID) based on the header field(s) and a content identifier (CID) based on the resource identifier. The PRID may be generated by applying a hash function to a string that includes header field data. The cNAP sends an outgoing ICN message that includes the CID and the PRID. In response, the cNAP receives an incoming ICN message that includes an HTTP response, a PRID, and a CID. The cNAP and directs the HTTP response to the appropriate client(s) based on the PRID and CID.

Dependent claims

A method performed by a client-side network attachment point (cNAP) on an information-centric network (ICN), the method comprising:

receiving from a client an HTTP request, wherein the HTTP request is associated with a fully-qualified domain name (FQDN) of a host, and wherein the HTTP request includes a uniform resource locator (URL) and at least one header field;
generating (i) a request proxy rule identifier (PRID) based on the at least one header field, (ii) a request content identifier (CID) based on the FQDN, and (iii) a request reverse content identifier (rCID) based on the URL;
sending an outgoing ICN message requesting data, the outgoing ICN message comprising the request CID, the request PRID, a node identifier of the cNAP, and the HTTP request;
in response to the outgoing ICN message, receiving an incoming ICN message comprising an HTTP response, a received PRID, and a received rCID;
and
in response to a determination that the received rCID and the received PRID are the same as the request rCID and the request PRID, respectively, providing the HTTP response to the client.
