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 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 discloses an intelligent lock device and a usage method thereof as well as a configuration method for electronic keys. The configuration method for the electronic keys comprises the following steps: I, generating two-dimensional codes corresponding to a specific intelligent lock, wherein the two-dimensional codes comprise basic configuration parameters and enciphered messages of communication corresponding to the specific intelligent lock; II, scanning the two-dimensional codes by a mobile client side, decrypting and reading data in the two-dimensional codes; III, establishing a first security channel by the mobile client side through using the analyzed two-dimensional data and the intelligent lock; IV, mutually sending the key information and secrete key information, configured in the first security transmission channel, through the mobile client side and the intelligent lock, and storing the key information and secrete key information as electronic keys. The intelligent lock device has standard safety and is simple to use and convenient to operate.

The invention discloses a realization method for an encryption algorithm of real-time transmission data, which comprises determining the iterative rounds used to conduct the encryption algorithm for the real-time transmission data, selecting one of a plurality of algorithms in an algorithms library according to a key when in each round of encryption iteration, and conducting the encryption algorithm for real-time transmission data using the data pack as a unit by combining the key. The invention further discloses a realization device for the encryption algorithm of real-time transmission data. The method is adopted to overcome the problems of low security coefficient brought by the encryption and complexity of strong encryption, and realize the security encryption effect for the real-timetransmission data, thereby solving various security threat problems faced by real-timely transmitted VoIP data.
