Abstract: A device is authenticated for communication over a network based on a sensor data signature and a traffic pattern signature. The sensor data signature and the traffic pattern signature identify the device. A determination is made whether the sensor data signature corresponds to one of a plurality of recognized sensor data signatures. A determination is also made whether the traffic pattern signature of the device corresponds to one of a plurality of recognized traffic pattern signatures. The device is authenticated for communication over the network responsive to determining that the sensor data signature corresponds to one of the plurality of recognized sensor data signatures and the traffic pattern signature corresponds to one of the plurality of recognized traffic pattern signatures.

Abstract: In some examples, a network controller includes a flow repository and a consistency verification engine. The flow repository may store a dataflow configuration previously specified by an application. The consistency verification engine may access the dataflow configuration from the flow repository, retrieve flow table entries from a flow table of a network device, identify an inconsistency between the dataflow configuration previously specified by the application and the flow table entries of the network device, and respond to the identified inconsistency.

Abstract: A verification framework is decentralized by implementing a database of Known Good States through a blockchain and smart contracts. In this manner, the system may provide an open platform to attest the integrity of various components, which may originate from different vendors. As such, the system supports attestation for multi-vendor infrastructures. In some instances, the system may leverage crypto-economics to monetize the platform. For instance, verifiers may be rewarded according to terms of a smart contract implemented on the blockchain network. Moreover, in some instances, the components may be delivered via an immutable file system, such as the InterPlanetary File System (“IPFS”). The IPFS is a decentralized file system based on a peer-to-peer protocol, improving file distribution efficiency. Components stored using IPFS each are assigned a unique identifier, which is a hash digest composition over the file's blocks. Thus, any modifications to the components may be detected via hash comparisons.

Abstract: According to examples, an apparatus may include a processor and a memory on which is stored machine readable instructions. The instructions may cause the processor to intercept a packet from a downstream service function classifier, in which the packet includes metadata that specifies an ordered set of service functions within a service function chain to be implemented on the packet, generate a correlation cookie that associates the packet with the service function chain, and encode the correlation cookie into the packet. The instructions may also cause the processor to store the correlation cookie and the metadata in a cache to correlate the correlation cookie and the metadata and send the packet with the encoded correlation cookie to the service function provider.
