[0003] However, when the user forgets the protection password, the ciphertext cannot be unlocked to obtain important electronic files, thereby causing losses to the user.
Especially when the electronic file is a public-private key pair, if the user forgets the protection password and cannot obtain the public-private key pair, the transaction signed by the public-private key pair will not be verified, resulting in heavy losses

The invention discloses a method, apparatus and system for resetting protection passwords, based on decryption cryptograph of a client, and relates to the technical field of data safety, being able to realize a function of resetting protection passwords even if a user forgets the protection password. The method for resetting protection passwords includes the steps: acquiring the input decryption secret key and the resetting secret key which are required when the protection passwords are to be reset, wherein the decryption key is generated according to biological characteristics of a human body, and the resetting key is generated according to the reset protection passwords; acquiring the required cryptograph from the server side when the protection passwords are to be reset, wherein the cryptograph is generated by means of encryption of the encryption key of the biological characteristic information of a human body; utilizing the decryption key to decrypt the cryptograph; and if decryption is successful, acquiring the plaintext corresponding to the cryptograph, and utilizing the resetting key to encrypt the plaintext to obtain the cryptograph corresponding to the resetting key, and sending a user ID and the cryptograph corresponding to the resetting key to the server. The method, apparatus and system for resetting protection passwords, based on decryption cryptograph of a client are mainly suitable for the scene where the biological characteristic information of a human body is utilized to reset the protection passwords.
Description
technical field [0001] The present invention relates to the technical field of data security, in particular to a method, device and system for resetting protection passwords based on client decrypted ciphertext. Background technique [0002] With the development of Internet technology, people are gradually accustomed to storing the data needed in work or life in electronic form in computers. In practical applications, people often save some electronic files locally on the client side for the convenience of query. However, since the client is vulnerable to attacks, in order to avoid the risk of some important electronic files (such as public-private key pairs), these electronic files are often encrypted with a protection password first, and then the ciphertext is sent to the server for storage. When the electronic file needs to be used, the terminal will display a protection password input prompt box, and then the terminal can decrypt the ciphertext through the input protect...
