Dependence diagram is with reference to Fig. 1.
Described timing microprocessor detects the electric weight of reserve battery, if electric weight less than 15% of total electric weight, then microprocessor log-on data self-destruction operation.
Described data self-destruction operation comprises that automatic deletion is used for the key of financial payment.
Described data self-destruction operation also comprises " deadlock " state that makes the microprocessor of secure payment terminal enter.
Specifically, the mechanism of uncap self-destruction key and critical data has comprised following 3 parts generally, and shell is opened or quilt is broken attacks in case detect, and then carries out the self-destruction action immediately.In case the reserve battery electric weight is about to exhaust, then carry out the self-destruction action immediately.
Part 1: standby power supply
Equipment at first must have reserce cell, this reserce cell is not powered to master cpu processor and monitoring module when equipment has external power supply, thereby the test section of the equipment of assurance and the normal operation of self-destruction partial circuit, this reserce cell needs to satisfy following two conditions at least:
1) chargeable
Battery can be recycled, when equipment inserts that external power source is normal and uses, can be to the action of charging of inner reserce cell, and the behavior safety that charges is reliable.
2) continue to use the date long
Reserce cell can use separately more than 3 years at least.(only supplying CPU and detection module).Can guarantee in the long time that so just CPU detects the shell state by detection module.
Take all factors into consideration, equipment must carry above lighium polymer rechargeable battery or a chargeable lithium button cell of 260mAH at least, can satisfy us to the demand of reserve battery.The lithium polymer battery charging is safe and reliable, and self-discharge rate is low.Be full of once electricity, can satisfy the testing time of equipment more than 3 years.
Part 2: detect the means of uncapping
The means that detection is uncapped are preconditions of self-destruction sensitive information and key, have only correct, sensitive detecting shell is opened or brokenly attack self-destruction two kinds of detection modes are arranged, and dual mode complements each other, and are jointly uncapped in the outside and broken the attacking of malice detected.
(1) equipment designs two contact points respectively at protecgulum and bonnet, the shell place of contact point top opposite position leaves conducting resinl, have when equipment closes and cover and accomplish fluently screw, then the conducting resinl at shell place is by tightly pressing, please referring to accompanying drawing two, this contact point by the state of conducting resinl pressing under, the CPU pin senses to level be low level.Can determine, when shell is in closure state always, the detection pin detects always and is low level, in this case, for power saving, CPU is in dormant state always, power consumption is at microampere order, prolong the service time of back-up source to greatest extent, in case shell is illegally opened by external force, the electric silica gel on the shell leaves the contact, can produce one from the low rising edge external interrupt wakeup CPU that uprises and notify the CPU shell to be opened at the detection pin, this detection means simple structure, cost is low, and difficulty of processing is low, can tackle the conventional shell means of tearing open, as: normally the equipment screw is opened, protecgulum or bonnet are taken away, just can detect very easily in this way and uncap.If but potential malicious persons is through groping after a while, after perhaps tearing several equipment open, found the position of electric silica gel, so, can tear tractor driver's section normally open fully, and then with broken mode of attacking, just can directly avoid the detection of uncapping of this mode such as above chip, directly opening " skylight ".In this case, in order effectively to survey the outside the broken of equipment attacked, it is just necessary that equipment increases the detection means 2 of uncapping simultaneously.
(2) since sensitive information and master control key be positioned within the safety chip; in order to protect near the shell the safety chip can effectively be detected after attacking by malice is broken; introduce photosensitive tube (SG-2BC); photosensitive tube always has 4 pin; inside is equivalent to have a photosensitive diode and a triode; please referring to accompanying drawing three; its principle is: the photodiode pin of photosensitive tube inside has the power supply supply; and when the light irradiation is arranged; control inner triode saturation conduction; when not having the light irradiation; triode is cut-off state; owing to introduced photosensitive tube; when shell is attacked when opening by malice is broken; device interior has light state from unglazed becoming; the photosensitive tube state changes; thereby cause that triode becomes conducting state from cut-off state in the photosensitive tube; the grid of outside Q1N-MOS pipe is at ordinary times owing to ending of triode keeps low level; Q1 is cut-off state; triode in photosensitive tube becomes conducting state from ending; can introduce a high level by Q1N-MOS tube grid externally; make Q1N-MOS become conducting state from ending; so just can become low level to the level that CPU surveys on the SENSOR pin from high level; thereby in the external interrupt that produces a negative edge; this interruption will wake dormant CPU up, be attacked by malice is broken thereby allow CPU detect shell.
Part 3: self-destruction
When CPU is known by the detection means of part 2 that present shell has been opened or attacked by broken, effective or electric power is sufficient as the standby power supply of fruit part 1, equipment enters duty immediately, (less than 1 second) deletes the pass key-encrypting key of its storage inside in the extremely short time, customer information, bank's private information, transaction record and other sensitive information, and in program, enter " deadlock " state, namely to any normal instruction in outside, the state that operation is not all responded, (chip itself does not have the hardware locking state, realize by software, in fact just in software, add a zone bit, if enter " deadlock ", in software is handled, just no longer comprehend any external command so), if having human-computer interaction interface such as display screen, then prompting, equipment is self-destruction, please return factory and office's reason.The equipment master cpu has AD measuring ability and time clock feature, can start an AD measuring ability every 1 day the standby power supply electric weight of part 1 is done one-time detection, if having approached, electric weight exhausts (less than 15% electric weight), prove that so the user had not used this equipment or frequency of utilization extremely to hang down near 3 years and caused the back-up source electric weight to exhaust, CPU directly deletes key and enters software " deadlock " state after with self-starting so, after preventing that back-up source because of part 1 from thoroughly not having electricity, all self check measures were lost efficacy.Reveal client's crucial sensitive information and key.
When equipment has carried out the self-destruction operation, the client has only the bank that returns delivery apparatus again, burned key and all kinds of sensitive information again, and utilize special instrument to withdraw from software " deadlock " state by equipment, could continue to use.
The secure payment terminal has the equipment backup battery, and backup battery adopts lithium polymer battery or lithium button cell.After backup battery is full of electricity, but continuous working (only supplied CPU and detection module) more than 3 years.
Have the silica gel push-button that is associated with shell and printed board copper foil circuit etc. on the circuit board of secure payment terminal.In case protecgulum or the bonnet of shell are opened, this type of on-off circuit will produce level to be changed, thereby wakes CPU deletion key up.
In case the backup battery electric weight is lower than to a certain degree, then the secure payment terminal is deleted responsive key and data automatically, in order to avoid after backup battery thoroughly exhausted, every detection means can't be carried out, thereby causes sensitive information to be revealed.
