Muaj nuj nqi ntawm encryption nti

1. Kev tiv thaiv kho vajtse:

Thaum tsim PCB, siv qee cov chips nrog encryption algorithm (xws li symmetrical algorithm (DES / SM1), asymmetric algorithm (RSA / SM2), digest algorithm (SM3 / SHA-256), thiab lwm yam). Txhawm rau txiav txim siab tus nqi, SHA-256 kho vajtse tsuas yog encryption nti feem ntau yog siv. (piv txwv li, Renault rjgt102) teeb tsa tus yuam sij hauv MCU thiab encryption nti feem, thiab tuav tes sib txuas lus ntau zaus hauv qhov program. Tus yuam sij no yog tsim los ntawm cov chaw tsim khoom.

2. Kev tiv thaiv software:

Yog tias koj cov khoom muaj nws tus kheej algorithm thiab muaj qhov zoo hauv kev lag luam. Tau kawg, kuv tsis xav kom kuv lub algorithm raug nyiag los ntawm lwm tus. Lub sijhawm no, peb tuaj yeem xav txog lub nti uas xav tau kev tiv thaiv software (xws li rjmu401 ntawm Wuhan renajet), uas tuaj yeem tsis tsuas yog cuam tshuam nrog kev tshawb pom Circuit Court hauv txoj kev no, tab sis kuj tiv thaiv kev tawm tsam sab nraud. Thiab tuaj yeem muab cov lej tseem ceeb lossis cov ntaub ntawv ntawm MCU rau hauv lub cim encryption, uas kuj muaj cov txheej txheem encryption.
