The application discloses a data processing method, a server, a client and an encryption machine. The method includes: receiving the first request sent by the client for requesting to determine a session key, and negotiating with the client on the session key; The second request generated based on the second session key is sent by the end, and the second request is verified based on the first session key; when the second request passes the verification, the first information is sent to the encryption machine, so that the encryption The machine processes the first information based on the client's personal key. By negotiating the session key between the client and the server, this method can build a secure channel between the two to ensure the information security of the interactive operation. By entrusting the personal key on the server or an encryption machine connected to the server, it can facilitate Customers use personal keys on different hardware devices for information processing, and can also avoid the loss of personal keys caused by the loss of hardware devices, and then avoid information security problems caused by this.

The invention provides an implementation method of an AES hardware encryption system based on a quantum reversible circuit, which belongs to the technical field of information security. The technical solution is: an AES hardware encryption system based on a quantum reversible circuit, including a quantum reversible circuit encryption and decryption module, a quantum secret key expansion module and a multi-interface selection module; the implementation method includes the following steps: realizing the quantum reversible circuit encryption and decryption module Hardware setting, complete the hardware setting of the quantum secret key expansion module, and use the electronic circuit to set the multi-interface selection module. The beneficial effects of the present invention are: the encryption and decryption module based on the quantum reversible circuit is combined with the quantum secret key expansion module according to algorithm rules to construct an encryption system based on the quantum reversible circuit, and the complexity of encryption is (2 n -1)! times, improve the encryption effect and anti-attack ability, and the multi-interface selection module can be connected with various interface devices to complete the encryption and decryption operations of various forms of information.

The invention relates to a safety computer with an information safety management unit.
