A method for logging in to a cloud terminal. A cloud terminal sends encrypted data and a hardware number to a cloud server; the cloud server searches for a public key and first user information according to the hardware number, decrypts the encrypted data according to the public key, and obtains second user information sent by the cloud terminal; the cloud server compares the first user information and the second user information, and if identical, the cloud server provides a cloud desktop environment to the cloud terminal. Also disclosed are a cloud terminal, a cloud server and a cloud system. The present invention implements two-factor authentication using a hardware device and user information, so that each user corresponds to a unique hardware device, and a private key is stored in the hardware device and cannot be exported, thereby ensuring the security of user information. |
