Multi-domain Optical Network Secure Optical Path Establishment Protocol Based on Hierarchical PCE

Abstract

The invention discloses a layered PCE-based multi-domain optical network security optical path establishment protocol, aiming at the security problems existing in the multi-domain optical network optical path establishment process and the problem of low comprehensive efficiency, combined with the trust model and key management scheme, adopting Globally optimized multi-domain trusted path selection, available wavelength calculation and wavelength allocation strategy, using TLS-based two-way identity authentication, TCP-AO-based source authentication, identity cryptography-based encryption and digital signature technology, and Path-Key-based Privacy protection mechanism, designed a new protocol based on global optimization secure light-path protocol based PCE in multi-domain optical network GO‑PCE (Global Optimizing secure light‑path protocol based PCE in multi‑domain optical network), which can meet the requirements of confidentiality and integrity , authenticity, non-repudiation, freshness and privacy and other security service requirements, compared with SD‑PCE and pH‑PCE optical path establishment protocols, it has a lower blocking rate and shorter optical path establishment delay.

Description

technical field [0001] The invention relates to the technical field of multi-domain optical networks, in particular to a multi-domain optical network security optical path establishment protocol based on layered PCE. Background technique [0002] In 2009, the IETF proposed the security requirements for the establishment of optical paths in multi-domain optical networks in RFC 5520, but no relevant effective solutions were proposed. In 2009, Professor Zhou Xianwei of Beijing University of Science and Technology proposed an ASON secure optical path establishment protocol, but this protocol is only suitable for single-domain optical networks. In 2004, Sun Weiqiang proposed a hybrid mode-based cross-domain optical path establishment protocol CLEP in literature [34]. In 2014, Wang Zongwei [35] A scheme to establish a cross-domain optical path based on SD-PCE and pH-PCE was proposed. In the same year, Qiu Zaimeng [36] Cross-domain solutions based on PCE-based optical networks ha...
