Cov ntaub ntawv kho dua tshiab txoj kev, cov cuab yeej hluav taws xob thiab kev cia nruab nrab thiab cov txheej txheem ntawm cov khoom siv chip rewriting

Technical realization cov ntsiab lus:

Txhawm rau kov yeej qhov tsis txaus ntawm cov duab ua ntej, ib qho khoom ntawm qhov kev tsim kho tam sim no yog muab cov ntaub ntawv

kev hloov kho dua tshiab rau lub tshuab luam ntawv siv cov khoom siv rov sau dua tshiab, uas paub txog kev hloov kho hloov kho yooj yim thiab kho dua tshiab.

rading ntawm chip rewriting ntaus ntawv cov ntaub ntawv.

Lub invention muab cov ntaub ntawv kho dua tshiab txoj kev rau ib tug chip rewriting ntaus ntawv, muaj xws li cov kauj ruam hauv qab no:

Pib lub hwj chim-on, lub nti rewriting ntaus ntawv yog powered on, pib lub nti rov sau dua lub cia

qhov chaw thiab qhov expansion interface ntawm lub cuab yeej, thiab mounting cov ntaub ntawv nyob rau hauv qhov chaw cia rau cov ntaub ntawv system

ntawm lub chip rewriting ntaus ntawv;

Lub khoos phis tawj sab saud txuas nrog txhawm rau txheeb xyuas seb lub khoos phis tawj sab saud txuas nrog qhov nthuav dav int-

Tsis tas li ntawd, qhov txuas txuas ntxiv yog tshwj xeeb yog USB interface.

Tsis tas li ntawd, cov kauj ruam ntawm lub hwj chim-on pib yog tshwj xeeb: pib ib daim npav SD, mounting SD card rau ib daim ntawv.

e system ntawm nti rewriting ntaus ntawv, pib lub USB, thiab enumerating USB MASS STORAGE.

Tsis tas li ntawd, cov kauj ruam hauv lub xeev kev txiav txim siab yog tshwj xeeb: txiav txim siab seb lub khoos phis tawj sab saud txais tos

ua tiav, thiab tom qab ntawd dhia los txiav txim siab seb qhov kev sib txuas ntawm lub khoos phis tawj sab saud puas raug txiav, lwm yam.

rwise rov qab los tau txais daim ntawv qhia tsis tiav thiab tos txais tos kom tiav; dete-

rmining seb lub computer sab sauv kev twb kev txuas yog off On, yog, rov qab cov kev twb kev txuas disconnection chij thiab

tos rau reconnection, txwv tsis pub dhia mus rau cov kauj ruam kev txiav txim.

Tsis tas li ntawd, ua ntej cov kauj ruam cov ntaub ntawv hloov tshiab, cov ntaub ntawv pov thawj yog ntxiv nrog, thiab cov ntaub ntawv hloov kho tau raug txheeb xyuas.

Yog tias cov ntaub ntawv hloov kho dua dhau qhov kev pov thawj, cov txheej txheem dhia mus rau cov kauj ruam cov ntaub ntawv hloov tshiab, thiab yog tias cov ntaub ntawv hloov kho dua tshiab

ua tsis tiav qhov kev pov thawj, cov ntaub ntawv yuam kev yog xa rov qab. .

Tsis tas li ntawd, cov kauj ruam ntawm kev txhim kho cov ntaub ntawv decryption tshwj xeeb yog siv AES algorithm los decrypt cov kev hloov kho tshiab.

le, thiab cov kauj ruam cov ntaub ntawv pov thawj tshwj xeeb tau txais kev kuaj CRC.

Cov khoom siv hluav taws xob muaj xws li: processor; nco; thiab ib qho kev pab cuam, nyob rau hauv qhov kev pab cuam yog khaws cia rau hauv lub

nco thiab teeb tsa kom raug tua los ntawm lub processor, qhov kev pab cuam suav nrog cov ntaub ntawv hloov kho dua tshiab rau ex-
