An image forming apparatus and an address book process request processing method are disclosed to improve access security to an address book. The image forming apparatus include an information storage part, a request receipt part and a request processing part. The information storage part stores an address book on users. The request receipt part receives process requests for the address book together with user identification information from users. The request processing part authenticates the users based on the received user identification information and performs operations corresponding to the process requests on the address book in accordance with access authority permitted to the users. The address book includes address information for transmitting data to the users via a network and management information having user identification information of the users.

The invention discloses an industrial control signal detection system and a detection method; the detection system comprises a data collecting module which collects real-time status data of equipment electrical features, and a historical process database which is connected with the data collecting module and used for storing the real-time status data collected by the data collecting module; the detection system further comprises a signal process predicating model which is connected with the historical process database and establishes correspondence between signal input and output in the electrical features based on the data inside the historical process database; the signal process predicating model obtains a predicated output signal based on the real-time input signal collected by the data collecting module, and sends the predicated output signal to a signal filter; the signal filter receivers the predicated output signal from the signal process predicating model and the real-time output signal collected by the data collecting module, and compares the signals, if the feature of the corresponding real-time output signal accords with the feature of the predicated output signal, then the real-time output signal is judged to be an effective executable signal; otherwise, the real-time output signal is judged to be a negative non-executable signal.

The invention relates to a novel safe network terminal based on single CPU double-bus. The novel safe network terminal provides resistance function to the known or unknown network instruction by physical insulation and access control, adopts a single CPU and a safe area system bus and a non-safe area system bus isolated physically, the bus bridge controls the dynamic connection of the CPU and thesystem bus, and realizes the physical insulation of the two system buses; the related internet communication apparatus is only connected to one bus, while the related safe data memory apparatus is connected to the other system bus; one sharing bus is used to share the bus communication between the keyboard, mouse and the other input / output equipment, and the inside and outside system. The invention can effectively prevent the network instruction, guarantee information safety, and have advantages of low cost, strong spreading functional, safety and reliability, and the like.

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.
