The invention discloses a method for double-factor bidirectional authentication. The method comprises the following steps: releasing a digital certificate and a CA certificate used for signature during the making of the digital certificate by a secret key system; configuring the configuration files of a client and a server-side so as to support the access of the client to an application interface of the server-side; accessing the application interface of the server-side by the client in a double-factor authentication mode; carrying out first verification on a server-side certificate by the client, carrying out second verification on a client certificate by the server-side, and after passing through of both the first verification and the second verification, allowing the client to access the application interface of the server-side. Besides, the invention discloses a system for double-factor bidirectional authentication, corresponding to the method. The method and the system for double-factor bidirectional authentication have the advantages of higher compatibility, wider application range, simpler design, more efficiency in use, and higher safety in data communication.

The present invention is directed to a system and method for secure communication of electronic documents to a document processing device. A document processing request containing electronic document data is received containing document data in an unencrypted form. A seed value is then received and used to generate a random number. The random number is used to encrypt the electronic document. The seed value, in a header, is transmitted, along with the encrypted electronic document, to a document processing device. The document processing device extracts the seed value from the header and uses the seed value to generate a random number. The encrypted document is then decrypted using the random number generated from the seed value. The document processing device subsequently performs the selected document processing operation on the decrypted electronic document.

The invention discloses a wireless real time location system and a wireless real time location method. The wireless real time location system comprises a label, a reader-writer and a location engine. The reader-writer comprises three radio frequency modules and three antennae. The label establishes three channels with the reader-writer by the three radio frequency modules and the three antennae. The reader-writer is connected with the location engine. The label and the reader-writer achieve data security and finish location computation by triple authentication. By the technical scheme provided by the invention, the security of data communication between the label and the reader-writer can be achieved, the capacity of the label can be increased and the location accuracy can be improved.

The invention discloses a unified identity management system of a distributed public certificate service network. A root public certificate service center and a regional public certificate service center are accessed to a backbone network; the user terminal accesses the backbone network through the backbone network access point; the regional public certificate service center is provided with a regional public certificate server and a regional administrator; the backbone network is a data communication network based on a UID address; wherein different devices and terminal users in the backbonenetwork have unique and different UID addresses; wherein the UID address format is C _ R _ X, C represents the country, R represents the region, and X represents the equipment or the terminal user; the terminal user applies to the regional public certificate service center to obtain a user UID address and a user public certificate; wherein the user UID address of the terminal user and the equipment UID address of the public certificate service center of the area to which the terminal user belongs have the same C and R; unified identities of network users can be automatically and effectively managed.

The invention provides a data communication method and device, electronic equipment, an upper computer and a storage medium. The method comprises the steps of responding to a received operation command sent by an object, determining at least one input entity corresponding to the operation command, sending the at least one input entity to a lower computer, receiving feedback information sent by thelower computer for the at least one input entity, analyzing feedback information, and determining a target receiver adopting the same communication protocol as the lower computer; setting the targetreceiver as a default receiver; and achieving data communication between the upper computer and the lower computer by using the default receiver. The feedback information is analyzed; a target receiver with the same communication protocol is determined as the lower computer according to the feedback information, the target receiver is determined as the default receiver, so that data communicationbetween the upper computer and the lower computer is realized, a serial port communication system does not need to be reset, the cost is saved, and the technical effect of safe and reliable data communication between the upper computer and the lower computer is ensured.

A removable data storage medium including a serial interface; a non-volatile storage medium; a memory controller controlling data transmission between the serial interface and the non-volatile storage medium, a receiving unit; and a write protection unit; wherein the receiving unit is configured to receive a device identification feature from a medical device that can be connected to the removable data storage medium; and the write protection unit is configured to compare the device identification feature with a predetermined internal criterion, and, if the device identification feature complies with the predetermined internal criterion, permits read and write access from the medical device to the non-volatile storage medium and, if the device identification feature does not comply with the predetermined internal criterion, limits access of the medical device to the non-volatile storage medium to read access.

The intelligent positioning and managing system comprises a fork truck positioning system and a fork truck managing system connected to the fork truck positioning system, and the fork truck positioning system comprises a monitoring center and fork truck terminal nodes connected with the monitoring center. According to the intelligent positioning and managing system, data communication relies on the strong GPRS communication network and is thus safe and reliable, a digital type screen is used to be more human-based, and software design based on host interface of PC provides convenience for expansion and improvement.

The invention provides an emergency command scheduling method and an emergency command scheduling system for a sudden environmental event. The method comprises the steps as follows: a mobile terminal acquires a RAS public key from a network server, and stores the RSA public key in a local memory; the mobile terminal encrypts login information by using the RAS public key, and sends the encrypted login information to a network server, wherein the login information comprises a session key, an account name, a login password and hardware equipment information of the mobile terminal; after verifying authenticity of the login information, the network server generates the login information into a login certificate and a user ID, and stores the user certificate and the user ID into a database server; the network server encrypts the user certificate and the user ID by using the session key and then sends the encrypted user certificate and user ID to the mobile terminal; and session data and the user certificate are encrypted by using the session key and then sent to perform communication between the mobile terminal and the network server. The system is used for implementing the above method. According to the method and the system provided by the invention, data communication security between the mobile terminal and the server can be ensured.

A remote control for an air conditioner facilitates setting of various kinds of data without operation of a button. A remote control (30) includes an external communication unit (45) having an NFC circuit (42) and an NFC antenna (43). The external communication unit (45) is capable of wirelessly communicating with an external apparatus even when a microcomputer (36) in the remote control (30) is not supplied with power (i.e., in a non-operating state). Hence, through the wireless communication between the external communication unit (45) of the remote control (30) and the external apparatus, the various kinds of data is forwarded from the external device to the remote control (30), and stored in the remote control (30).
