Title:
ENCRYPTION METHOD FOR LOGIN INFORMATION, DEVICE, ELECTRONIC DEVICE, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/114122
Kind Code:
A1
Abstract:
The present solution is applicable in the technical field of the internet. Provided are an encryption method for login information, a device, an electronic device, and a medium. The signature of a device is acquired, the signature is rearranged according to a preset rule and then converted into a signature character string, the signature character string is complemented to produce a complementary character string, according to the locations of signature sets in the complementary character string, signature set abstracts of the signature sets are sequentially calculated, the signature set abstract of the last signature set is made as a device fingerprint, the device fingerprint is converted into an encryption key applicable in encryption, and the encryption key produced on the basis of the device fingerprint is used per a preset encryption algorithm in the encryption of login information, thus producing login ciphertext. This allows different devices to be provided with encryption keys different from that of other devices and prevents the login ciphertext from being decrypted even if the encryption algorithm and the login ciphertext are acquired by someone else, thus better ensuring that login information of a user is not fraudulently used by others.
