Method for realizing dynamic authentication deploying and canceling defense control by using deploying and canceling defense controller and alarm host computer

Abstract

The invention relates to a method for realizing dynamic authentication deploying and canceling defense control by using a deploying and canceling defense controller and an alarm host computer in a security and defense system. After match code in the match-code operation process is completed, the deploying and canceling defense controller and the alarm host computer calculate the address of the deploying and canceling defense controller according to an encryption algorithm corresponding to encryption algorithm codes in a match code instruction and respectively generate a dynamic authentication ID which is stored; and after authentication in the deploying and canceling defense operation process is completed, the deploying and canceling defense controller and the alarm host computer calculate the previous generated dynamic authentication IDs according to the encryption algorithm corresponding to the encryption algorithm codes in a deploying defense or canceling defense instruction and respectively generate a new dynamic authentication ID which is stored for next deploying and canceling defense operation, so that each match code operation and deploying and canceling defense operation can generate a new dynamic authentication ID for the authentication of the next deploying and canceling defense operation. Therefore, the deploying and canceling defense control of dynamic authentication can be realized, signals can be effectively prevented from counterfeiting and the security of the security and defense system can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of security systems, in particular to the technical field of arming and disarming control in the security system, and specifically refers to a method for realizing dynamic authentication arming and disarming control by an arming and disarming controller and an alarm host. Background technique [0002] All kinds of security alarm hosts with anti-theft alarm function need to have two working states of "arming" and "disarming". Traditional arming and disarming control methods include the following two methods: [0003] 1. Control through a wired or wireless keyboard connected to the host. Generally, you need to press the arm or disarm function key, or enter the menu to select the arm or disarm option, and then enter the user password through the keyboard to arm and disarm the alarm panel. The defect of this control method is that the user must operate through the keyboard and remember the password, which is c...

Problems solved by technology

However, this method also has the following problems: when the user uses the remote control normally, the remote control itself does not authenticate the user's identity. If a remote control is taken by an outsider, it can also arm and disarm the security host. Therefore, There is a big security risk

Swipe the card on the arming and disarming controller for identity authentication, and then arm or disarm, but the fixed signal between the arming and disarming controller and the host is easy to be intercepted and forged, and there are still certain security risks
