Embodiment 1

[0080] Based on the above inventive concept, this embodiment introduces a network security credible audit method for regulation and business services applicable to 5G networks, including:

[0081] Obtain original audit data, wherein the original audit data is audit data with the management center slice network as the target transmission direction;

[0082] Encrypt and sign the original audit data to generate signed encrypted audit data;

[0083] transmitting the signed and encrypted audit data to each node of the management center slicing network, and obtaining the data transmitted to each node as the data to be audited;

[0084] Hash calculation is performed on the encrypted audit data in the data to be audited of each node respectively, and the hash value corresponding to each data to be audited is obtained;

[0085] Build a Merkle tree based on the obtained hash value;

[0086] Obtain the hash value in the root of the Merkle tree and the signature value in the data to be ...

Embodiment 2

[0089] Based on the same inventive concept as Embodiment 1, this embodiment makes further improvements on the basis of the technical solution of Embodiment 1.

[0090] The method for trusted auditing network security of the regulation business applicable to the 5G network in this embodiment further includes: encapsulating the data to be audited obtained from each node and the Merkle tree information into a data block with a time stamp, and adding the data block to the area blockchain;

[0091] In the method, obtaining the hash value in the root of the Merkle tree and the signature value in the data to be audited on any node is: obtaining the hash value in the root of the Merkle tree and any one from the block body of the blockchain The signature value in the data to be audited on the node.

[0092] In the method, if the final verification fails, the audit error information is also stored in the corresponding block.

[0093] refer to figure 1 As shown, this embodiment specif...

Embodiment 3

[0118] With the inventive concept based on Embodiments 1 and 2, this embodiment introduces a network security credible auditing device for regulation business applicable to 5G networks, including:

[0119] an original audit data acquisition module, configured to acquire original audit data, wherein the original audit data is audit data with the management center slice network as the target transmission direction;

[0120] The encryption signature processing module is configured to encrypt and sign the original audit data to generate signed encrypted audit data;

[0121] a data acquisition module to be audited, configured to transmit the signed and encrypted audit data to each node of the management center slice network, and acquire the data transmitted to each node as the data to be audited;

[0122] The data to be audited data hash calculation module is configured to perform hash calculation on the encrypted audit data in the data to be audited of each node respectively, to o...

Abstract

The invention discloses a regulation and control service network security credible auditing method and system suitable for a 5G network, and relates to the technical field of smart power grid security, and the method comprises the steps: obtaining original auditing data, carrying out the encryption and signature processing, and generating signed encrypted auditing data; transmitting the signed encrypted auditing data to each node of the management center slice network, and obtaining to-be-audited data transmitted to each node; performing hash calculation on the encrypted audit data in the to-be-audited data to obtain hash values; constructing a Merkle tree on the basis of the obtained hash value; acquiring a hash value in the Merkle tree root and a signature value in the to-be-audited data on any node, performing verification processing, and if verification is passed, decrypting encrypted audit data in the to-be-audited data to obtain original audit data and outputting the original audit data; and if the verification is not passed, outputting auditing error information. According to the method, the credibility and tamper-proofing of the network audit data can be ensured, and the accuracy and consistency of node data are ensured.

Description

technical field [0001] The invention relates to the technical field of smart grid security, in particular to a method and system for trusted auditing of network security of a regulation business suitable for a 5G network. Background technique [0002] Since the characteristics of 5G communication are highly compatible with the needs of power communication, the integration of 5G networks and power grids can bring better service provision and economic benefits to the power industry. With the integration of 5G technology and the power grid, the smart grid has begun to transform into a 5G+ smart grid. At the same time, 5G has also led to the extension of the grid boundary, and the network attacks suffered by the grid network have also increased. of increase. [0003] A large amount of data is transmitted in the smart grid, including user electricity privacy data, real-time electricity price data, resource scheduling data, and communication data between basic grid equipment. It...
