Password anti-out-of-control system and method based on motion state perception

Abstract

The invention provides a password anti-out-of-control system based on motion state perception, the password anti-out-of-control system comprises encryption equipment carried on an airborne / missile-borne platform, wherein the encryption equipment is composed of an encryption equipment host and a protection medium, and the encryption equipment host comprises a control unit, an acceleration sensor, anonvolatile storage unit and a volatile storage unit; the protection medium is used for storing and storing protection information; the nonvolatile storage unit is used for storing protected passwordkey data; the volatile storage unit is used for storing the bright-state password key data; the acceleration sensor is used for collecting a motion state; the control unit is used for decrypting theprotected password key data and storing the decrypted protected password key data into the volatile storage unit; and the password instruction is run and the bright password key data is destroyed according to the motion state. According to the scheme, the nonvolatile memory only stores protected password key data, so that daily safety management of equipment is facilitated; encryption equipment automatically senses the task stage switching condition of the weapon platform through a sensor, and automatically destroys internal bright-state password key data.

Description

technical field [0001] The invention relates to the field of encryption, in particular to a system and method for anti-out-of-control encryption based on motion state perception. Background technique [0002] The encryption equipment deployed on the weapon platform usually solidifies the key data PCS of clear encryption such as application key, application algorithm and algorithm parameters in the non-volatile storage unit of the cipher machine, which is used for the communication command or Information such as intelligence and reconnaissance provides encryption protection, and weapon platforms are tricked into capture or missiles do not explode, especially airborne and missile-borne encryption equipment. Once the equipment is out of control, the key data PCS of the clear state password may be illegally obtained by hostile users. risk, will affect the normal use of all equipment of this type. [0003] The current system requirements for encryption devices are as follows: ...

Problems solved by technology

[0005] 2) After the weapon platform is out of control, the key data PCS of the encryption device internal clear state password cannot be obtained by the opponent

[0006] After the weapon platform is out of control, on the one hand, the weapon platform has left the wireless communication coverage area designed by the system or is unable to communicate normally due to electromagnetic interference, etc., and the encryption system cannot use wireless communication means to remotely destroy the key data PCS of the encryption device's clear state encryption online; On the other hand, after the weapon platform is out of control, it may be in a power-off state, and the encryption equipment cannot work. It cannot be judged that the weapon platform is in an out-of-control state, nor can it destroy the key data PCS of its non-volatile storage unit.
