Embodiment Construction

[0020] The scheme will be described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The direct purpose of key synchronization is to call the key management system in different places to obtain the same key, so as to use the key to encrypt, transmit, and decrypt some important information. However, based on the problems raised in the background art, the present application proposes the following solutions.

[0022] figure 1 For a schematic flowchart of a two-point key security synchronization method provided by the embodiment of this application, see figure 1 , the two-point key security synchronization method provided by the embodiment of this application includes:

[0023] S101. After the first user sends the generated first primary key to the second user, encrypt a first key verification value of the first primary key with a node key to obtain an encrypted key verification value.

[0024] In this embodiment, the first user...

Abstract

The invention discloses a two-point key secure synchronization method and system, and equipment. The method comprises the steps: after a first user transmits a generated first primary key to a second user, encrypting a first key verification value of the first primary key through a node key, and obtaining an encryption key verification value, enabling the first user to send the encryption key verification value to a second user; and processing the first primary key according to the information fed back by the second user; and after the first user sends the generated key to the second user, verifying the key received by the second user through the unique identifier key verification value of the key, and if the key verification values are inconsistent, discarding the key. The keys between the two parties are kept synchronous, so that the problem that the two parties of data communication perform data interaction under the condition that the keys are not synchronous is avoided.

Description

technical field [0001] The present application relates to the technical field of key synchronization, in particular to a two-point key security synchronization method, system and equipment. Background technique [0002] Key synchronization is an important link to ensure the security of data transmission in the field of data communication. The key to secure key synchronization is the key for the caller to use the key to encrypt and decrypt normally. At present, in the field of key synchronization technology, the mechanism of key security synchronization is relatively complete. Generally, in order to ensure key synchronization, the caller will send the key to the receiver through a secure channel after encrypting the data with the key. [0003] However, if there is a network problem or the communication request is modified, the sent key will be inconsistent, which will cause the received key to be out of sync, and the data receiver will not be able to decrypt the encrypted dat...
