Description
Technical field
The present invention relates to a kind of computer mandate opening control systems and method based on computer booting key.
Background technology
With the progress and development in epoch, computer becomes the work that people become more and more important in daily working and learning
Tool, extensive use and all trades and professions have also shown its shortcoming or even its negative work while it brings convenience for us
With, such as the safety of its information, data, the operating time can not be controlled etc..Although there are many safety measures at present, such as
Startup password, nearly 300 sections of encryption softwares are set.But these methods all seem very powerless, even draw a snake and add feet to it.It is one slight
U disks can crack, and those security softwares are just even more meaningless, the software based on operating system, as long as system is changed
Just without any effect.
For this problem of computer security, have become an old problem and can not thoroughly solve the problems, such as always.
Various security softwares, various startup passwords.Finally being cracked slowly during practical application, is eliminated.To find out its cause,
Or because it be based on computer in itself or based on system, be based on bios.When system and bios have no longer been problems
It waits, these so-called so-called safety measures of encryption are equal to " zero ".
The prior art is primarily present following technological deficiency：
First, it is authenticated after computer energization work, if authentification failure, computer rests on working condition or anti-
Multiple restarting carries out repeating certification, is easy to cause computer service life reduction or hardware damage；
Second, it is easily cracked, some lawless peoples brush the bios information after malicious modification again into computer, encryption
Method fails, and computer loses safeguard protection, be easy to cause loss of data or deleted by lawless people, monitors；Such as：Bios is set
Startup password is put.System is provided with user password.System is mounted with a variety of encryption softwares.One password cracking u disk plugs weight
It opens, bios passwords will be cleared.Encryption software.Startup password.Can usb-hdd be selected by boot disk.Get out one
A mobile hard disk that system is pre-installed.Into the system of u disks.Data can be deleted by copy.
Third, the encryption method based on mainboard bios program are easily distorted by hacker or virus.Virus CIH prevailing for a time
It exactly specially rewrites bios and burns the virus of hardware.
