Abstract

The invention discloses a security authentication method and device and a storage medium. The method comprises the following steps: encrypting a message abstract of target content by using a public key in an asymmetric key to obtain a user signature; encrypting the message content included in the target content by using a symmetric key to obtain encrypted content; and sending a request message containing the user signature and the encrypted content to a receiving end, and sending the request message to a receiving end, thereby enabling the receiving end to carry out security authentication onthe request message. The request message is used for requesting target data associated with a user identifier of a target user corresponding to a sending end, the request message further comprises theuser identifier, and the asymmetric secret key and the symmetric secret key have a unique corresponding relation with the user identifier of the target user. According to the method and the device, the technical problem that the message transmission security is poor due to the fact that the symmetric key is intercepted in the transmission process is solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a security authentication method and device and a storage medium. Background technique [0002] At present, the security authentication method of the open data platform is: the client uses a pre-assigned symmetric key to encrypt the content to be transmitted, and the open data platform uses the same symmetric key as the client to decrypt the received message: if If the decryption is successful, the corresponding business processing will be performed according to the decrypted content; if the decryption fails, it will be considered as an illegal request and cannot pass the authentication. [0003] Since the content of the message is encrypted using a symmetric key, the symmetric key is easily intercepted during transmission, so there is a problem of poor message transmission security. [0004] For the above problems, no effective solution has been proposed yet. Contents of the ...
