Example Embodiment

[0064] The specific embodiments of the present invention are as follows:

[0065] First, perform port detection to check whether the connection between the server's ip and port is normal. If it is normal, the connection between the system and the server is established. After the connection is successful, the key verification starts. The system and the server preset the initial password. When the system triggers the authentication operation, The system and the server use the same method to discretize the initial password to obtain the first random key. The system uses the first random key and SM4 encryption method to encrypt the first random number to obtain the first ciphertext, and combines the first random number and the first password. The text is sent to the server, and the server uses the same method to encrypt the first random number to obtain the second ciphertext, compare the first ciphertext and the second ciphertext, if the same, the key verification is completed, and th...

Abstract

The invention discloses an account password changing method, system and device, and the method comprises the steps: building connection with a server, and generating a first random secret key according to a preset initial password after the connection is successful; generating a first ciphertext and a second ciphertext based on the first random key, and verifying the first ciphertext and the second ciphertext; generating a random number after verification succeeds, and obtaining a second random key and a third ciphertext according to the random number; and encrypting the account information based on the second random key and the third ciphertext to obtain encrypted data. The system comprises a connection module, a first secret key module, a second secret key module and an encryption module. The device comprises a memory and a processor for executing the method for changing the password of the account. The security of the account information can be improved. The invention can be widelyapplied to the field of account information security.

Description

technical field [0001] The present invention relates to the field of account information security, in particular to a method, system and device for changing account encryption. Background technique [0002] Currently, there are very few products on the market that can change the account password of the hard-coded system. Most of the hard-coded systems still modify the account password by manually modifying the configuration file. There is no operation record for manual modification, and sometimes the operator may not be on time and regularly. Modification, manual modification cannot guarantee timeliness, and modification of account password may affect the normal operation of the business, so the security of confidential information cannot be guaranteed. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a method, system and device for changing account encryption, which can improve t...
