A cryptographic anti-runaway system and method based on motion state perception

Abstract

The present invention provides a cryptographic anti-out-of-control system based on motion state perception, which includes an encryption device mounted on an airborne / missile-borne platform, the encryption device is composed of an encryption device host and a protection medium, and the encryption device host includes a control Unit, acceleration sensor, non-volatile storage unit and volatile storage unit; protection medium, used to store and store protection information; non-volatile storage unit, used to store protected password key data; volatile storage unit, used to store clear The key data of the state code; the acceleration sensor is used to collect the motion state; the control unit is used to decrypt the key data of the protected code and store it in the volatile storage unit; run the code command and destroy the key data of the clear state code according to the motion state. In the solution of the present invention, the non-volatile memory only stores the key data of the protected password, which is convenient for daily security management of the equipment; the encryption device automatically senses the switching of the task stage of the weapon platform through the sensor, and automatically destroys the key data of the internal clear password.

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 cryptographic 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 communication command or Information such as intelligence and reconnaissance provides encrypted protection, and weapon platforms are tricked into capture or missiles do not explode, especially airborne and missile-borne cryptographic 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 password devices are as follows: ...

Problems solved by technology

[0005] 2) After the weapon platform is out of control, the key data PCS of the clear state encryption inside the encryption device 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 equipment in the clear state; On the other hand, after the weapon platform is out of control, it may be in a power-off state, and the cryptographic 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.
