Problems solved by technology

[0005] However, this structure is less secure. For example, when criminals pry open the casing, the circuit board and battery will be lifted out together because they are integrated with the casing. Sensitive information remains intact so it can be easily obtained by simply duplicating the data held in the board

Abstract

The invention discloses a hot melting detachment prevention dynamic token and a detachment prevention method of the hot melting detachment prevention dynamic token. The hot melting detachment prevention dynamic token comprises a shell, a circuit board used for storing information, and a battery. The shell comprises a shell body and a cover body used for being buckled on the shell body, and further comprises an elastic sheet. The battery is arranged between the circuit board and the elastic sheet. The circuit board, the battery and the elastic sheet are arranged in the shell body. The shell body is arranged on the side close to the elastic sheet. A protruding hot melting column is arranged on the side, facing towards the elastic sheet, of the shell body. The shell body penetrates through the elastic sheet through the bolt melting column and is welded to a through hole of the circuit board. According to the method, when the hot melting detachment prevention dynamic token is detached, the circuit board is cocked, the elastic sheet is separated from the circuit board in the position of the hot melting column, and therefore the circuit board and the battery are separated. The power outage effect is achieved for the circuit board and the battery through a simple detachment method, and therefore integrity of sensitive information stored in the circuit board is improved.

Description

technical field [0001] The invention relates to the technical field of information security protection, in particular to a hot-melt tamper-proof dynamic token and a tamper-proof method thereof. Background technique [0002] A dynamic token is a product used to authenticate secure identities, and its own security depends on the security of sensitive information stored internally. [0003] According to the GM / T0021-20127.2.3 of the "People's Republic of China Encryption Industry Standards", "tokens should be protected from obtaining sensitive information in the device through physical attacks. The means of physical attacks include but are not limited etc.” This poses a new challenge for dynamic tokens, namely to physically effectively implement tampering. [0004] Existing dynamic tokens generally include a casing and a circuit board arranged inside the casing and used to store sensitive information; meanwhile, a battery is fixedly connected to the surface of the circuit boar...
