The invention discloses a method, device and equipment for safely starting an RAID card and a computer readable storage medium. The method comprises the steps of calling an SM3 algorithm to conduct hash operation on the RAID card to be started to obtain a measurement value; reading a reference value of the RAID card prestored in a configuration register, wherein the reference value is obtained byconducting corresponding operation on the RAID card through calling of the preset algorithm when the RAID card is started for the first time; since the RAID cart started for the first time is safe andcredible, by judging whether the measurement value of the RAID card to be started is equal to the reference value or not, judging whether the RAID card is safe or not, if yes, starting the RAID card,and if not, stopping starting the RAID card. By means of the method, device and equipment for safely starting the RAID card and the computer readable storage medium, verification of safety of the RAID card is provided before the RAID card is started, it is guaranteed that the RAID card started in a server is safe and credible, and therefore the safety of the server is improved.

The invention discloses a pulse signal acquisition circuit which is practical, safe and reliable. The pulse signal acquisition circuit comprises an input pulse signal and an output pulse signal, wherein the input pulse signal can be converted into the output pulse signal through shaping of a pulse shaping circuit, and an overvoltage protection circuit is arranged between the input signal and the pulse shaping circuit. The overvoltage protection circuit arranged between the input pulse signal and the pulse shaping circuit enables the whole circuit to be safe and reliable.

The embodiment of the invention provides a safe update method and device for cooling strategy configuration, and a controlled terminal. The method comprises the following steps that: obtaining and encrypting a cooling strategy parameter configuration file; uploading and decrypting the encrypted cooling strategy parameter configuration file to a BMC (Baseboard Management Controller); and updating the cooling parameter to a new cooling strategy parameter configuration file, and executing parameters in the new configuration file by the BMC. By use of the method, when a cooling engineer needs to revise and update the PID (Proportion Integration Differentiation) speed regulation parameter and the linear speed regulation parameter of the temperature of an air inlet, the encryption certificate ofa current server manufacturer is used for encryption, corresponding certificate decryption is carried out in the BMC so as to achieve the safe verification of the configuration file, finally, only the correct cooling strategy configuration file is generated, illegal personnel can be prevented from tampering the configuration file, and the risk of server crash is lowered.

The invention discloses a multifunction door and window. The multifunction door and window comprises a door body and a security check channel arranged in a machine body in a front and rear communicating mode, the bottom of the security check channel penetrates through the bottom end face of the door body, first guiding sliding grooves are formed in the left and right inner walls of the security check channel in a communicating mode, and second guiding sliding grooves located at the rear ends of the first guiding sliding grooves are formed in the left and right inner walls of the security checkchannel in a communicating mode. A cavity extending front and back is formed in the top of the security check channel, third guiding sliding grooves with openings downwards are formed in the four corners of the bottom end face of the door body, a second cavity is formed in the top of the first cavity, the first guiding sliding grooves are internally and slidably connected with first guiding sliding blocks in a fit mode, and a plurality of security brake bars extending left and right are arranged on the first guiding sliding blocks. The multifunction door and window has simple structure, convenient operation, safety and stability, convenient installation and accurate detection.

The invention relates to an identity information effectiveness identification method and device. The method comprises the following steps: (1), inputting is performed: unique identification feature information and loss report information of an identity card are input into a database of a server; (2), query is performed: the unique identification feature information of the identity card is read by a terminal and inquired in the database of the server; (3), a verification result of the unique identification feature information and the loss report information of the identity card is obtained according to a query result. The method can perform effectiveness check on the identity card in three aspects including the authenticity of the identity card, whether the identity card loses efficacy or not and consistency of the identity card and a holder, that is, whether the identity card belongs to the holder.

The invention relates to a VRS grid point zero trust checking system and method. The method comprises the steps of receiving VRS grid point data generated by a CORS computing system; decoding the VRS grid point data, and intercepting illegal messages; detecting the decoded VRS grid point data and rejecting the data which cannot provide the CORS service; eliminating the data of which the consistency of the observation data of the VRS grid points and the geometric model of virtual coordinates does not meet the requirement; and coding the VRS grid point data and pushing the coded VRS grid point data to a corresponding positioning terminal. According to the invention, the safe and rapid verification of the VRS data is realized, and the safety and reliability of the data are improved; satellite data with the precision error not meeting the requirement are eliminated, and the data precision and reliability are guaranteed. The gross error checking is fast and effective, and a large amount of computing resources are prevented from being occupied.

The invention provides an equipment authentication information cascade updating method and device, and belongs to the technical field of smart home. The method comprises the following steps: when equipment performs user authentication, the equipment authenticates local authentication information input by a user; if the local authentication information passes the authentication, the equipment acquires temporary authentication information associated with the local authentication information and authenticates the temporary authentication information, and the server sends the temporary authentication information to the equipment at preset time intervals; if the temporary authentication information passes the authentication, the equipment determines that the user passes the authentication. According to the method disclosed in the invention, security verification can be carried out in equipment authentication, and related authentication information can be updated more efficiently, securely and secretly.
