USBKEY mining machine

1. 1. USB key is a kind of hardware device with USB interface. It has a built-in MCU or smart card chip, has a certain storage space, can store the user's private key and digital certificate, and uses the built-in public key algorithm of USB key to realize the user's identity authentication. Usb-hdd is a hard disk simulation mode. After DOS starts, C: disk is displayed. The U disk made by HP U disk format tool uses this mode. The compatibility of this mode is very high, but for some computers that only support usb-zip mode, it can't be started. The two are only similar in writing, with very different meanings
2. Considering that it may be a writing error, briefly introce the other startup modes of USB flash disk:
a. usb-zip: large capacity floppy disk simulation mode. After DOS starts, a disk will be displayed. Usb-zip made by flashboot starts the USB flash disk in this mode. This mode is the only optional mode on some older computers, but it is not compatible with most new computers, especially the large capacity USB flash disk
B. usb-hdd +: enhanced usb-hdd mode. After DOS starts, C: disk is displayed, with high compatibility. The disadvantage is that it can't be started on the computer which only supports usb-zip
C, usb-zip +: enhanced usb-zip mode, support usb-hdd / usb-zip al-mode startup (according to different computers, some BIOS may display C: disk after DOS startup, some BIOS may display a: disk after DOS startup), so as to achieve high compatibility. The disadvantage is that some computers that support usb-hdd will start the USB disk in this mode as usb-zip, which will rece the compatibility of large capacity USB disk above 4GB
D. usb-cdrom: CD simulation mode, DOS can be started without occupying the drive letter, so the compatibility is general. The advantage is that XP / 2003 can be installed like a CD. Generally, it needs the mass proction tools corresponding to the specific USB flash disk model / batch number.

1. The first step is to obtain a digital certificate. You need to open online banking and apply for a digital certificate. After you get the password envelope to download the digital certificate, you can download the certificate. The digital certificate can be stored in USBKEY or in the browser of the computer. At this time, it means that you already have your own unique digital certificate

you may ask, what is it and why use USBKEY? USBKEY is a safe and convenient storage medium. The appearance of USBKEY is similar to that of an ordinary USB flash disk. The difference is that it contains smart chips. The user's information downloaded to USBKEY is unique and cannot be copied. Anyone who wants to transfer the funds in the account on the Internet must pass the USBKEY customer certificate for unique authentication in advance. As long as you take USBKEY with you, even if the account number and password are leaked, but you can't get USBKEY, others can't impersonate you

2. In the second step, you can login online banking safely. When using online banking, you need to insert USBKEY into the computer and enter the password of USBKEY. At this time, in the network behind the computer, the bank and your digital certificate will confirm each other's identity. That is to say, check whether the bank's website is real, not the fake website made by lawless elements, and whether your identity is correct, not the hacker pretending to be you. After the authentication of both sides is true, a secure encrypted channel will be established between you and the bank. At this time, you can safely log in to personal online banking. The whole process is automatic and can be completed in a few seconds

After the verification of the identities of both you and the bank, the operation instructions of your account will be transmitted in an encrypted secure channel. No one can tamper with this information on the network, nor can they break your account information. Especially at the end of your fund transfer transaction, when the system prompts you to confirm this operation, you may not know. After you click & quot; Determine & quot; At the same time, the operation time, operation type and operation amount of this transaction have been electronically signed and saved by your digital certificate system. This preserved and unchangeable signature can be taken out in the future to verify whether there was such a transaction at that time, providing factual evidence for possible disputes in online transactions

If you lose your digital certificate or USBKEY, please inform the bank in time to reissue your digital certificate.

who should issue the digital certificate

1. The digital certificate should be issued by the third party security certification authority (CA) which is independent of the user and the bank. The third-party CA takes part of the responsibility of online information security for customers and banks, and avoids certain risks for customers and banks

for example, in the case of online banking disputes, the third party CA can provide proof for customers and banks who use digital certificates for online banking transactions, so as to clarify the responsibilities of both parties. If the bank is offside, when CA issues the digital certificate to the user, it means that the bank is not only a referee but also an athlete. In case of dispute, it is difficult to guarantee the fairness of the proof provided

2; China financial certification authority (CFCA); Digital certificate issued. This is an authoritative, reliable and impartial third-party security certification body, and also the only third-party security certification body in the financial instry. Most banks use the digital certificates issued here. When you apply for online banking in a bank branch, you can directly apply for the CFCA digital certificate from the branch. The Bank branch will also provide you with a letter of responsibility for CFCA digital certificate and a letter of commitment for CFCA digital certificate service, which also clearly promises the amount of compensation for your losses caused by the digital certificate.
