Embodiment Construction

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] At present, under the SDN architecture, the existing optical layer / electrical layer network status data collection or network in-band telemetry technology does not take into account the privacy and security of telemetry data. Therefore, the embodiment of the present invention provides a telemetry data analysis system based on privacy protection, the overall system architecture is as follows figure 1 shown.

[0021] The data plane is divided...

Abstract

The invention discloses a telemetry data analysis system and method based on privacy protection. The telemetry data analysis system and method solve the problem of eavesdropping by encrypting telemetry data. Meanwhile, encrypted data is signed by adopting a hash technology based on data compression, and a control plane verifies the integrity of the data by utilizing a signature, so tampering attacks are effectively prevented. A privacy protection scheme of the invention has relatively low complexity and does not influence the correctness and real-time performance of system processing.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a privacy protection-based telemetry data analysis system and method. Background technique [0002] With the rapid development of network facilities and the increasingly diverse needs of network users, the network operating environment has become more and more complex. Therefore, real-time, fine-grained, end-to-end flow status information is a necessary condition for quickly discovering and locating network faults. In-band network telemetry technology (INT, In-bandNetworkTelemetry) is regarded as the most promising network status acquisition solution, which monitors the status information of the data plane in real time through in-band data transmission, saves network bandwidth and ensures real-time network status. At the same time, the software-defined network (SDN, Software Defined Network) separates the data plane and the control plane, and the centralized controller co...
