Data security device and its tamper-proof machine network

Abstract

Disclosed are a data security device and an anti-disassembling machine network thereof. The anti-disassembling machine network comprises a switch matrix which comprises a plurality of switch nodes; a circuit is communicated between the adjacent switch nodes; every switch node is corresponding to a control state and can be controlled to be located in one of a plurality of switch states; the control states of the switch nodes form a control sequence; the switch states of the switch nodes form a switch sequence; every switch sequence is corresponding to a network path; the switch matrix comprises a plurality of Hamilton paths; a plurality of control sequences which are used for controlling the switch nodes to be connected into the plurality of Hamilton paths are calculated out in advance and stored in an ROM (Read Only Memory). The data security device and the anti-disassembling machine network thereof can effectively prevent an attacker from utilizing a reverse engineering method to obtain an anti-disassembling machine network structure to attack.

Description

technical field [0001] The present invention relates to data security, in particular to the physical protection of critical data. Background technique [0002] In the era of rapid development of computers, many electronic devices are becoming more and more widely used in people's lives. Electronic data storage is the basic application of these electronic devices such as computers, and it also provides great convenience for consumers of all levels. People have become more and more dependent on the convenient and efficient lifestyles provided by various electronic devices, and various large and small enterprises also rely on electronic devices to meet the various needs of their consumers. With the increasing requirements and the general public's emphasis on the protection of personal privacy, the security of such electronic data has become an increasingly important topic. [0003] For data in electronic devices or storage devices, if there are no security protection measures...
