The invention provides a single sign-on tamper-proofing method and device,
computer equipment and a storage medium. The method comprises the following steps: obtaining first login information of a user
logging in a
server, associating the first login information with a first tag, generating a private key and a public key which are bound with each other, packaging and encrypting the first tag in the public key, and storing the public key in a session
library of the
server, thereby realizing the
encryption of the tag, and preventing an illegal person from inputting the tag into the session
library and directly entering the
server; sending the private key to a pre-associated terminal device; obtaining a to-be-verified private key input by the user through the
terminal equipment; judging whether the to-be-verified private key is the same as a private key or not, if yes, searching whether a public key corresponding to the private key exists in a session
library, if yes, decrypting the public key by the private key to obtain a first
label, and obtaining first login information corresponding to the first
label to log in a server again through the first login information, thereby realizing single sign-on of a user.
