Encryption method, device and equipment based on key update distribution and storage medium

Abstract

The invention relates to the field of information security, and provides an encryption method, device and equipment based on key updating and a storage medium, which are used for improving the security and reliability of a communication encryption mechanism. The encryption method based on key updating comprises the following steps: encrypting message sending information for sending a service message through an advanced encryption standard key to obtain first encrypted message sending information; generating first key information according to the old asymmetric key expiration information; encrypting the first secret key information through an effective receiver asymmetric public key to obtain second secret key information; sending the second secret key information to a receiving end, so that the receiving end obtains secret key confirmation updating information based on the secret key updating request; and when key confirmation update information sent by the receiving end is received, performing triggering encryption processing on the message sending information for key update message sending according to the new asymmetric key and the effective time so as to obtain second encryptedmessage sending information. In addition, the invention also relates to a blockchain technology, and the message sending information can be stored in the blockchain.

Description

technical field [0001] The present invention relates to the field of information encryption and decryption of information security, in particular to an encryption method, device, equipment and storage medium based on key update. Background technique [0002] With the development of Internet of Things technology and computer technology, information communication security has become a direction of concern, and communication security has also become an important field of information security, especially for the financial industry, customer information, transaction information or other sensitive information Leakage of leaks may cause more direct and significant economic losses. From this, it can be concluded that a safe and reliable cooperative communication mechanism is the cornerstone of the smooth development of business. [0003] At present, in the communication between partners in the financial industry, various professional institutions will use various encryption mechanis...
