Embodiment 1

[0057] The first key update method is given here, applied to the first device, such as figure 2 As shown, key update methods include:

[0058] Step 201: Obtain the key update request of the service node corresponding to the first device, and generate corresponding key update information for the key update request; wherein, the key update information includes at least service node information and a new key;

[0059] Step 202: Send key update information to at least one second device, so that at least one second device can verify the validity of the key update information to obtain a verification result;

[0060] Step 203: receiving a verification result of at least one second device, and generating a corresponding block for the new key based on the verification result of at least one second device;

[0061] Step 204: Send the block to at least one second device, so that the at least one second device adds the block to the local blockchain to generate a new blockchain.

Embodiment 2

[0074] In order to better reflect the purpose of the present invention, on the basis of Embodiment 1 of the present invention, further illustrations are made, such as image 3 As shown, the key update method specifically includes:

[0075] Step 301: Obtain the key update request of the service node corresponding to the first device, and generate corresponding key update information for the key update request; wherein, the key update information includes at least service node information and a new key;

[0076] Step 302: Send key update information to at least one second device, so that at least one second device can verify the validity of the key update information to obtain a verification result;

[0077] Step 303: When the verification results of at least N second devices in at least one second device are valid, determine that the key update information is valid; generate a corresponding block for the new key;

[0078] Step 304: Send the block to at least one second device,...

Embodiment 3

[0093] In order to better reflect the purpose of the present invention, on the basis of Embodiment 1 of the present invention, further illustrations are made, such as Figure 4 As shown, the key update method specifically includes:

[0094] Step 401: Obtain the key update request of the service node corresponding to the first device, and generate corresponding key update information for the key update request; wherein, the key update information includes at least service node information and a new key;

[0095] Step 402: Send key update information to at least one second device, so that at least one second device performs validity verification on the key update information to obtain a verification result;

[0096] Step 403: receiving a verification result of at least one second device, and generating a corresponding block for the new key based on the verification result of at least one second device;

[0097] Step 404: Send the block to at least one second device, so that at ...

Abstract

The embodiment of the invention discloses a secret key updating method and device and a storage medium, and the method comprises the steps: obtaining a secret key updating request of a business node corresponding to a first device, and generating corresponding secret key updating information for the secret key updating request, wherein the key updating information at least comprises service node information and a new key; sending the key updating information to at least one piece of second equipment, so that at least one piece of second equipment performs validity verification on the key updating information to obtain a verification result; receiving a verification result of at least one second device, and generating a corresponding block for the new key based on the verification result ofat least one second device; and sending the block to at least one second device, so that at least one second device adds the block to a local block chain to generate a new block chain. Therefore, thesecurity of the secret key information and the secret key updating efficiency can be greatly improved.

Description

technical field [0001] The present invention relates to blockchain technology, in particular to a key update method, device and storage medium. Background technique [0002] The key in the mesh network system is divided into two parts: private key, certificate, and symmetric key. These two parts need to be transmitted and stored through different channels to ensure security. The private key and certificate are generated by the Management Center (MC), and are manually distributed and installed in the encryption machine to encrypt the symmetric key. [0003] figure 1 Shows a mesh network key update process, when the Beijing service node (Service Node, SN) key leaks or is not available, the Beijing SN sends a key update request to the mesh network headquarters SN, and the headquarters SN passes the mesh network MC After receiving the application from SN, a new key will be generated, and the newly generated key will be synchronously updated to all SNs through the database link...
