The invention discloses a wireless network connection method, device and system, belonging to the field of network security. The method comprises the following steps: a user terminal sends an access request to a wireless access point; the wireless access point sends a key query request to an authentication server; the authentication server sends a corresponding key query result to the wireless access point when the wireless access point belongs to a trusted wireless access point; the wireless access point acquires a corresponding authentication key; the user terminal generates an authentication key corresponding to the own MAC address; and the wireless access point and the user terminal negotiate to establish an encrypted wireless network connection according to the separately-owned authentication keys. According to the wireless network connection method, device and system disclosed by the invention, the problem that both the data transmitted to the fake public Wi-Fi by the user terminal and the internal data of the user terminal are subject to security threats can be solved; and only the trusted wireless access point can acquire the authentication key to establish the encrypted wireless network connection with the user terminal, and the effect of improving the security of the data transmitted by the user terminal and the internal data of the user terminal can be achieved.

The present invention relates to a method of managing a mobile multicast key using a foreign key. More specifically, the present invention relates to a method of managing a mobile multicast key using a foreign key for secure communication between a mobile terminal and a secure relay server in the region where microwaves from plural access points overlap. A method of managing a mobile multicast key using a foreign key according to the present invention has an advantage that multicast secure relay servers perform delegated authentication in advance in a region where microwaves overlap, thus reducing a delay time for authentication in a mobile terminal and it has an advantage that it can minimize an effect from changes in group keys that user's movement make, by using a primary group key and a foreign key. This results in a reduction of an overhead from update of a group key while moving, and accordingly a reduction of a delay time. In addition, it has an advantage that it centralizes functions of key management to a secure relay server, thus overcoming the limitations on processing ability or network bandwidth of a mobile terminal.

The invention discloses a WEB vulnerability scanning method, apparatus and system for at least solving the problem that the network information security of internet users is threatened due to the overlong interval time between the discovery and identification of vulnerabilities in the prior art. The WEB vulnerability scanning method comprises the following steps: obtaining and storing a vulnerability scanning tool provided by a vulnerability detection terminal, wherein the vulnerability scanning tool is an extensible scanning tool programmed for a specific website vulnerability; determining the applicable vulnerability type of the vulnerability scanning tool provided by the vulnerability detection terminal, and displaying the vulnerability scanning tool provided by the vulnerability detection terminal and the applicable vulnerability type; obtaining a vulnerability scanning tool selection request sent by a to-be-detected website, and determining the vulnerability scanning tool corresponding to the vulnerability scanning tool selection request; and scanning the to-be-detected website through the vulnerability scanning tool corresponding to the vulnerability scanning tool selection request.

The embodiment of the invention discloses a wireless network connection method, device and system, belonging to the field of network security. The present invention sends the first access request to the wireless access point; sends the second access request to the authentication server; verifies whether the wireless access point belongs to the trusted wireless access point, and communicates with the user terminal when it belongs to the trusted wireless access point Perform the first identity authentication, negotiate with the user terminal to generate a master key; send the master key corresponding to the user name to the wireless access point; negotiate with the user terminal to establish an encrypted wireless network connection according to the master key; The data transmitted by the public Wi-Fi and the data inside the user terminal will be threatened by security; only the trusted wireless access point can obtain the master key corresponding to the user name, so as to communicate with the user terminal according to their respective Some master key negotiations establish an encrypted wireless network connection, which improves the security effect of the data transmitted by the user terminal and the internal data of the user terminal.

The invention provides a control method, a control module and an automobile. Wherein the control method is applied to the automobile, and includes the following steps: receiving a vehicle body lockingrequest; judging whether the automobile is powered off; and if not, controlling the automobile to perform a body locking operation according to position information of key of the automobile, and therefore, a vehicle body can be locked when the automobile is not powered off, and the safety of articles in the automobile is ensured.

The invention discloses a device for realizing IP address cheating-proof on AN and a relative method, wherein the method comprises that AN according to the character of DHCP protocol report extracts a DHCP protocol report from received reports, and confirms the relative user port information, AN detects the DHCP protocol report to obtain the setting information distributed for user host, comprising an IP address and a relative lease period, bonds the IP address and the relative user port information, and combines the lease information and following received reports, to maintain obtained user setting information, AN according to the user setting information filters received ascending report, and when the user IP address and port information in the report are not bonded, thinking the reportas illegal one. The invention can resolve IP address cheating-proof problem of malicious user, when uses DHCP dynamic host to automatically set protocol at IPoE access mode.

The invention relates to the technical fields of wireless communication network and network security, in particular to a method and a system for a WMAN (wireless metropolitan area network) entity exiting from a network. The method of the invention comprises the following steps that: a terminal accesses a base station on the network side after passing the identification of an authentication server, and the authentication server records the IDs of the terminal and the base station and corresponding relationship thereof; a service communication is carried out between the base station and the terminal; the authentication server revokes the certificate of the terminal; the authentication server sends a 'notice information for terminal exit' according to the recorded local IDs of the terminal and the connected base station and corresponding relationships thereof; the base station removes the service connection with the terminal to be exited from the network, and interrupts the service communication; and the base station sends a 'response information for terminal exit' to the authentication server. In the invention, when the ID of some terminal of the wireless metropolitan area network fails, or some terminal is set as an illegal user by a manager, the method and the system of the invention can make the terminal timely exit from the communication network so as to ensure the safety ofthe communication network.

The invention provides a preparation method, device and application of a modified PVC material with NTC effect. The raw materials are placed in a vertical mixing tank, and the raw materials are mixed and stirred by the vertical mixing tank until they are plasticized to obtain a semi-finished product; step (3), the semi-finished product is put into an extruder, and the extruder is used to Extrusion granulation is carried out to obtain a modified PVC material with NTC effect. The invention is convenient for people to quickly replace different die heads, so as to switch to produce plastic particles of different sizes, and after changing the die head, the die head and the connecting channel are pressed tightly, thereby increasing the sealing performance, preventing the raw material from overflowing, and improving the stability Higher and easier to clean.
