Abstract

The embodiment of the invention discloses a method, device and system for synchronizing sensitive data, computer equipment and a computer readable storage medium. The method comprises the following steps: uploading a first equipment long-term public key and a short-term public key, and obtaining the long-term public key and the short-term public key of second equipment; generating a shared key according to the first equipment long-term private key, the short-term private key, the long-term public key of the second equipment and the short-term public key of the second equipment; acquiring the encrypted sensitive information of the second device from a server, wherein the encrypted password is the shared key; and decrypting the encrypted sensitive information by using the shared key. Therefore, in the sensitive information synchronization process, the transmission of the sensitive information is always in an encrypted state, and the sensitive information is ensured not to be leaked to anintermediate server or other attackers. The newly generated shared key is used for the encryption key of the sensitive information each time, so that the forward security is ensured, and an attackercannot decrypt the previously encrypted information even if the attacker breaks through the latest encryption key.

Description

technical field [0001] The embodiments of the present application relate to the video field, and in particular to a method, device, system, computer equipment, and computer-readable storage medium for synchronizing sensitive data. Background technique [0002] Various apps of users need to synchronize sensitive personal information between different devices. Generally, there are three ways to synchronize sensitive information: first, Signal’s Seasame protocol is used to synchronize messages between different devices of the user. To ensure the forward security of each message, a redundant Double Ratchet is designed. X3DH key exchange protocol. The second is the general scheme of trusting the central server, which needs to trust a central server. The device uploads sensitive information to the server, and the server stores it. When other devices join, the sensitive data is sent to other devices. This solution needs to trust the central server. If the central server has insuf...
