Description

A kind of energy mark extraction apparatus for USBKey

Technical field

The present invention relates to cryptographic algorithm analyzing and testing field in smart card, particularly relate to a kind of extraction of the energy mark for USBKey.

Background technology

USBKey (hardware digital certificate carrier) is the Client Solutions that most of domestic bank adopts, USBKey is used to deposit representative of consumer unique identities digital certificate and private key for user, the use of USBKey make to pay more convenient, function more comprehensively, service is more various, it is safer to conclude the business, but the fail safe of the appearance of side-channel attack to USBKey constitutes threat.So-called side-channel attack (SideChannelAttacks), namely there is the leakage of the information such as energy, electromagnetism, mistake and time in hardware encryption electronic equipment in the engineering of process information, and the information utilizing these to reveal is attacked cryptography electronic equipment.Side-channel attack can be divided into power analysis, Electromagnetic attack and fault analysis etc., and wherein power analysis is higher because of efficiency, becomes the Main Means of side channel.

Side channel energy analytical attack is the energy ezpenditure produced when carrying out the operation such as Encrypt and Decrypt or signature by gathering the hardware encryption electronic equipments such as encryption chip, utilizes cryptography and Principle of Statistics etc., analyzes and decode a kind of attack pattern of key information.The basis that side channel energy is attacked is the energy ezpenditure that the effective hardware encryption electronic equipment of acquisition produces when Encrypt and Decrypt or signature etc. operate.

In view of the above problems, be necessary the scheme providing a kind of energy mark for USBKey to extract, thus carry out the channel energy analytical attack research of further side.

Summary of the invention

The object of this invention is to provide the scheme that a kind of energy mark for USBKey extracts, extract problem to solve existing USBKey energy mark.This USBKey energy mark extraction apparatus can conveniently effectively extract the power consumption in USBKey work.

To achieve these goals, technical scheme of the present invention is such: a kind of energy mark extraction apparatus for USBKey of the present invention, comprises main control module, usb communication module, serial communication modular, energy mark extraction module, trigger module and power module.The data interaction of described master control module controls external USB Key and single-chip microcomputer and the data interaction by serial communication modular and usb communication module and external equipment, USBKey passes through usb communication model calling to main control module, PC or other embedded devices are connected to main control module by serial communication modular, described energy mark extraction module extract USBKey and PC or other embedded devices alternately in energy trace curve, described trigger module is used for the energy mark that extracts of trigger external collecting device collection, and described power module provides power supply for modules.

As preferably, described main control module comprises single-chip microcomputer.
