Abstract
The utility model discloses an energy mark to CPU formula smart card draws appearance, include host system, do smart card drive module that host system controlled, do smart card signal interaction module that smart card drive module controlled and be used for drawing the trigger module that module and control were drawed to the energy mark that the smart card consumption goes on drawing. Current signal acquisition's technique has a lot, does not nevertheless have the technique of drawing to the consumption of CPU formula smart card at present at home as yet, an energy mark to CPU formula smart card draws appearance can effectually draw CPU formula smart card consumption signal.
Description
Technical field
The present invention relates to cryptographic algorithm in smart card and analyze detection field, particularly relate to the extraction of a kind of energy mark for CPU formula smart card.
Background technology
At present, CPU formula smart card has become the carrier of all kinds of cryptographic algorithm and has been widely used, and side Multiple Channel Analysis to all kinds of cryptographic algorithms on equipment realize safety constitute practical threat.Side Multiple Channel Analysis utilizes the various information that cryptographic algorithm is revealed in software and hardware implementation to carry out cryptanalysis, is not intended to the execution time of leakage, electromagnetic radiation, sound, energy, fault output etc. including cryptographic algorithm when performing.Reveal the difference of information type according to bypass, side-channel attack can be divided into power analysis, EMP attack N and fault analysis etc., and wherein power analysis is higher because of efficiency, becomes the Main Means of side channel.The difference of the energy expenditure of different operating obtain the information such as key in conjunction with statistical mathematics when the principle of side channel energy analytical attack is to be performed on equipment by cryptographic algorithm, CPU formula smart card also increasingly comes into one's own as its security study of carrier of the important cryptographic algorithm of a class.The domestic equipment still not extracted for CPU formula smart card energy mark at present, thus the realization of side-channel attack is had higher practicality and scientific research value by the equipment that the side channel energy mark designing a CPU of being specifically designed for formula smart card extracts.
Summary of the invention
For the vacancy in existing CPU formula smart card energy mark extractive technique, the invention provides a kind of energy mark extraction apparatus for CPU formula smart card, this energy mark extraction apparatus can convenient effective extraction CPU formula smartcard power consumption signal.
The technical scheme is that and be achieved in that:
A kind of energy mark extraction apparatus for CPU formula smart card includes main control module, the smart card driving module, the Smart card signal interactive module driving module to control for described smart card and the trigger module extracted for the energy mark extraction module that smartcard power consumption is extracted and control that control for described main control module.
Main control module, for controlling the data interaction of smart card and single-chip microcomputer；
Smart card drives module, for driving smart card to realize the normal operation of smart card；
Signal interactive module, the signal for realizing single-chip microcomputer and smart card is mutual and the signal interactive module of this energy mark extraction apparatus and outer PC or external signal collecting device；
Energy mark extraction module, is used for extracting smartcard power consumption signal；
Trigger module, is used for controlling external equipment and obtains effective energy mark.
The embodiment of the present invention provides a kind of CPU formula smart card energy mark extraction apparatus, module drive smart card normal operation is driven by master control module controls smart card, main control module gathers the energy mark of smart card work, this energy mark actually voltage signal after energy mark extraction module while driving smart card to drive module work by trigger module trigger external signals collecting storage facilities.The present invention has filled up the vacancy that there is no CPU formula smart card energy mark extraction equipment in prior art.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of a kind of energy mark extraction apparatus for CPU formula smart card of the present invention.
Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearly, describe the present invention below in conjunction with the drawings and specific embodiments.
Refer to shown in Fig. 1, a kind of energy mark extraction apparatus for CPU formula smart card of the present invention includes main control module 101 and the smart card driving module 102 controlled thereof, the single-chip microcomputer of main control module and Smart card signal interactive module 103, signal interactive module comprises the realization rs 232 serial interface signal interactive module mutual with external equipment signal and usb signal interactive module simultaneously, and the energy mark extraction module 104 that smartcard power consumption is extracted, wherein it is used for controlling external equipment by the trigger module 105 of master control module controls and energy mark is acquired.
Described main control module 101 is single-chip microcomputer.Described smart card drives module 102 to be smart card driving chip and circuit.Described signal interactive module 103 is single-chip microcomputer and communication protocol of intelligent card and realizing and rs 232 serial interface signal interactive module that external equipment signal is mutual and usb signal interactive module.Described energy mark extraction module 104 be by current signal on smart card feeder ear VCC or on GND current signal be converted into the circuit of voltage signal.Described trigger module 105 is an external interface module by master control module controls, for controlling effectively to collect the energy mark of smart card.
Compared to existing signal extraction technology, a kind of CPU formula energy mark extraction apparatus of the present invention can extract by the convenient effective energy mark to the work of CPU formula smart card, and not yet appears for CPU formula smart card in existing signal extraction technology.
Of particular note, for the common skill personnel of this area, the equivalence change for the present invention made under the guidance of the present invention, the scope that the present patent application the scope of the claims is advocated must be included in.
