Embodiment Construction

[0043] In the present invention, the term "substrate" refers to any structure having a surface on which an integrated circuit structure can be formed, including, for example, doped and undoped semiconductors, epitaxial semiconductors supported by base semiconductors and insulators, and Other semiconductor structures known to the skilled person. In the present invention, the materials selected for the substrate include but are not limited to silicon (Si), germanium (Ge), gallium arsenide (GaAs), cadmium telluride (CdTe) and the like. In the present invention, a substrate formed with a pattern or a circuit system is also called a semiconductor chip or a die. Since the formed pattern can realize a certain circuit function, in the present invention, unless otherwise specified, the term circuit system and integrated circuit can be used interchangeably with the pattern formed on the surface of the substrate. In addition, those skilled in the art will realize after reading the speci...

Description

technical field [0001] The invention relates to information security technology, in particular to a data processor with the function of preventing intrusion and an embedded system using the data processor. Background technique [0002] Data security is always an important consideration in applications involving sensitive or confidential information. Some embedded systems, such as financial terminals, authentication, and any system that stores passwords and encryption keys, require strong measures to protect their data. Additionally, the risk of physical exposure is particularly acute in applications such as automated teller machines (ATMs). [0003] A common approach to introducing security mechanisms in embedded systems is to provide an encryption boundary that surrounds keys, programs, and data, and when physical and cryptographic intrusions are detected, the system can quickly erase the stored keys, programs, and data . For example, the secure microcontroller DS5250 fr...
