Data secure transmission method, system and device and storage medium

The invention discloses a data security transmission method, system and device and a storage medium, and relates to the technical field of data security. The secure data transmission method comprises the following steps: generating an asymmetric key pair in response to a data transmission request of a client, the asymmetric key pair comprising a public key and a private key; sending the public key to a client, so that the client encrypts data by using the public key to obtain ciphertext data; storing a private key of the asymmetric key pair in a storage space, setting a private key timer, and deleting the private key from the storage space when the private key storage time exceeds a preset duration; and receiving a data message containing ciphertext data from the client, and obtaining a private key from the storage space to decrypt the ciphertext data. According to the invention, the security of data transmission can be improved. 本发明公开一种数据安全传输方法、系统、装置及存储介质，涉及数据安全技术领域。数据安全传输方法包括以下步骤：响应于客户端的数据传输请求，生成非对称密钥对，其中，所
