Abstract: An electronic device of a content producer generates a chunk of data, associates a location-independent name with the chunk of data, generates a signature for the chunk of data, attaches the signature to the chunk of data, and transmits the chunk of data, with the signature attached, to one or more user devices in response to respective requests. The signature is generated based on the data in the chunk, using a private key of the electronic device. The electronic device also stores information, including a specification of a public key associated with the private key, in a first ledger entry of a blockchain, to provide the one or more user devices with access to the public key. A user device may obtain the public key and use it to verify the chunk of data.

Abstract: A consumer sends to a producer Interests to request data packets of a data stream that are generated at a production rate. Each data packet includes a name of the data stream, a segment of data, and a current segment number that identifies the data packet in the data stream and that increments as the data packets are generated. The Interests include the name and segment numbers of segments requested by the Interests. The consumer synchronizes the segment numbers with the current segment numbers and a rate for sending the Interests to the production rate. The consumer sends to the producer the Interests at the rate and with the segment numbers as synchronized, in order to minimize a delay time between when the data packets are generated and when the data packets are received at the consumer. The consumer receives from the producer data packets satisfying the Interests.

Abstract: A method is provided in one example embodiment and may include generating a first interest message for a consumer application of a first node, wherein the first interest message comprises a content name within an Internet Protocol identifying content to be received by the first node; opening an Information-Centric Networking (ICN) socket for the first node, wherein the ICN socket is associated with the content name and the consumer application; and transmitting the first interest message to an IP network, wherein the IP network comprises at least one hybrid ICN-enabled routing node that is capable of performing packet forwarding using both IP networking constructs and ICN constructs.

Abstract: In one embodiment, a delivery service provided by a device receives one or more Messaging Layer Security commit messages comprising a plurality of public and private keys for a Messaging Layer Security group. The delivery service identifies subsets of the plurality of public and private keys to be sent to different destination subgroups in the Messaging Layer Security group. The delivery service maps each of the subsets to Hybrid Information-Centric Networking names. The delivery service sends, based on the Hybrid Information-Centric Networking names, the subsets of the plurality of public and private keys to destination subgroups in the Messaging Layer Security group.

Abstract: Presented herein is a solution in which a Producer that provides Transport Layer Security (TLS) over a hybrid Information Centric Network (hICN) announces two different hICN prefixes or namespaces. One hICN prefix is for performing a TLS handshake (also called a handshake prefix or handshake namespace) and another hICN prefix (also called a secure prefix or secure namespace) is to publish content in a secure, and confidential manner with a Consumer that correctly performs a TLS handshake. While the handshake prefix is public and shared by multiple Consumers, a secure prefix is uniquely assigned to a Consumer after the TLS handshake successfully terminates. Content published under the secure prefix is encrypted with the encryption key established during the TLS handshake. Names used in the secure namespace are private, meaning only the Consumer and Producer that perform the handshake can infer any information about a content by looking on the name.
