Cipher machine with secret key destroying function and secret key destroying method

Abstract

The invention discloses a cipher machine with a secret key destroying function and a secret key destroying method. Wherein the cipher machine shell is movably connected with the cover plate; a password card is arranged in the password machine shell; the cipher card is configured to trigger key destruction at a low level. A first control switch is arranged on the cipher machine shell, a second control switch is arranged at the packaging position of the cipher machine shell and the cover plate, the first control switch and the second control switch are electrically connected with the cipher cardthrough connecting wires, and the first control switch and / or the second control switch are / is controlled to control on-off of the cipher card. When a secret key needs to be destroyed or the cipher machine is illegally destroyed, the cipher machine is opened; a password card in the password machine is powered off; the high-level signal is switched into the low-level signal, automatic secret key destruction is directly triggered, an external program or system is not needed, the success rate of secret key destruction is high, the secret key can be rapidly destroyed in millisecond-level time, the cipher machine is prevented from being violently opened or violently cracked, and the safety of the secret key in the cipher machine is protected to the maximum extent.

Description

technical field [0001] This application relates to the technical field of information security, in particular to a cipher machine with key destruction and a key destruction method. Background technique [0002] Information security is a multi-level, multi-factor, and comprehensive dynamic process. Information security requires comprehensive thinking and unified planning of information systems and organizational systems. Information security must also pay attention to changes in the internal and external environments of the monitoring system. Information security is likely to be Security flaws on the system will pose a threat to the entire system organization. Therefore, information security is a multi-level, multi-factor, and comprehensive dynamic process. It is a continuous development process of information security that needs to be guaranteed by the system. [0003] The cipher machine is the basic core cryptographic device in the field of information security. The secur...

Problems solved by technology

However, traditional cipher key destruction is generally based on programs or systems. When key destruction is required, the key destruction program is controlled to execute the key destruction function. However, the program or system needs a start-up time, so key destruction cannot be guaranteed. timeliness, there is a certain risk to key security
