Household security system and method for generating initial disarming password thereof

Abstract

The invention discloses a method for generating an initial disarming password of a household security system. The method comprises the following steps: S1) reading an IMEI (International Mobile Equipment Identity) number of a fixed-line phone; S2) taking p as any prime number less than the IMEI number and q as any prime number more than the IMEI number; S3) setting n=pq and f(n)=(p-1)(q-1), taking any integer e, and calculating d, wherein e is more than 1 but less than f(n), gcd(e,f(n)) is equal to 1, and (ed)mod(f(n)) is equal to 1; and S4) selecting the undisclosed one of e and d and randomly selecting s numbers from the numbers forming the selected e or d as the initial disarming password of an authorized user household installed with the fixed-line phone. The invention also discloses the household security system used for realizing the method. The initial disarming password obtained according to the method is ultrahigh in safety, thereby being beneficial to increasing the security capability of the household security system for each authorized user household.

Description

technical field [0001] The invention relates to a family security system, in particular to a method for generating an initial disarming password of the family security system and a family security system for realizing the method. Background technique [0002] In order to improve home safety, people have proposed the concept of home security system. For example, based on China Mobile's M2M (Machine to Machine, machine-to-machine) platform and China Mobile's TD (Time Division, Time Division) wireless fixed-line telephone set, a special TD that can be used for home security defense has been developed. The wireless fixed-line telephone is the "Yijutong" product. The Yijutong TD wireless fixed-line telephone is realized by adding a security module to China Mobile's TD wireless fixed-line telephone. [0003] In the existing home security system, authorized users can choose whether to turn on the home security function at home according to actual needs. For example, when the autho...
