Cross-network dynamic service flow verification method and system, storage medium and computing device

Abstract

The invention discloses a cross-network dynamic service flow verification method and system, a storage medium and computing equipment. The method comprises the steps of uploading node address information and a public key to a blockchain through a PBFT consensus mechanism, and achieving the network access application of a node and the distributed secret key storage for a self-signature certificate.Aiming at the service request behavior of the node, based on a consensus mechanism of a block chain, the distributed verification node carries out verification, service serial number generation, service abstract uplink storage and service flow permission return on the node identity to realize cross-network service request uplink recording. Aiming at a service completion requirement required by across-network service flow in sequence, real-time service and processing node information are uploaded to a block chain by introducing a service completion identification mechanism, so as to realize effective verification of service continuity. Aiming at the situation that the cross-network service is tampered in the transmission process, a historical routing path tracking technology is utilized to mine malicious network segments possibly existing in cross-network service flow transmission, and the possibility of tampering the service flow again by the malicious network segments is reduced byidentifying bad routing nodes in the retransmission process.

Description

technical field [0001] The invention belongs to the technical field of network security and communication, and in particular relates to a cross-network dynamic service flow verification method, system, storage medium and computing equipment. Background technique [0002] With the increase of network nodes, the traditional CA center-based authentication method has problems such as bottlenecks in cross-network security transmission efficiency and insufficient flexibility due to centralized trust dependencies. In addition, since cross-network business flow transmission passes through many heterogeneous networks, the complexity and uncontrollable security of heterogeneous networks will inevitably threaten the reliability of network nodes, the order of business flow scheduling, and data privacy. For this reason, how to design a reliable, consensus-based cross-network dynamic business flow verification technology to ensure the confidentiality of business data privacy, the order of...

Problems solved by technology

[0003] Generally speaking, the main reasons for the low efficiency and low reliability of cross-network service flow verification can be roughly divided into the following three aspects: First, because more and more nodes access the network rely on the centralized authentication mechanism of CA, CA The center provides great authentication computing power, and the centralized storage is vulnerable to attacks, causing the key leakage of the CA center, causing attackers to use the CA authentication key to produce fake certificates and destroy the overall network security; secondly, due to the complexity and variety of network services Due to the lack of effective verification of the orderliness and security of business flows in the existing cross-network communication mechanism; finally, due to the complexity of heterogeneous networks, the existing cross-network business flow technology cannot effectively avoid the retransmission of business flows In the process, the mistakes of the previous insecure routing network segments are repeated, which makes the effective transmission and processing of cross-network services encounter efficiency bottlenecks
