Abstract
The invention discloses a method for encrypting computer system, comprising the following steps of: a, coding and translating encryption and decryption program codes into a BIOS; b, running a password program; c, reading the serial number of hard disks, if the serial numbers are present, entering the step h, or entering the step e; e, executing backups of the serial numbers of hard disks in the BIOS; f, encrypting the hard disc guide sectors and partition table sectors; g, rebooting the hardware system and performing the step c after the BIOS is electrified; h, reading the backup serial numbers of hard disks in the BIOS; I, judging whether the two serial numbers of hard disks match with each other, if so, entering the step k, or entering the step j; j, showing an error hint and shutting down the computer; k, decrypting the hardware system guide sectors and partition table sectors. As the encryption and decryption programs are coded and translated by the BIOS at the same time, and embedded into the BIOS in the binary manner, the passive following is avoided and the computer has higher safety.
Description
Technical field
The present invention relates to a kind of computing machine and count a tree name safeguard protection field, specifically, be meant a kind of encryption method of computer system.
Background technology
At present, the research and development input of computer software is very huge, particularly computer system software.Yet the user in a lot of areas is really very thin to the intellectual property right consciousness of computer software at present, cause pirate market extensively to exist, flourishing long time, each fatware company not only will keep on improving on software function, and not irrevocably lost in order to prevent that research and development from dropping into, and also need rack one's brains in software cryptography, software enciphering method commonly used at present has manufacturer that serial number encryption is provided, or USB is provided, softdogs such as LPT are encrypted, omnifarious encryption methods such as over-network registration authentication.
Yet present software enciphering method all has defective more or less.
Such as our common sequence number authentication, it is followed the tracks of and cracks by the people than being easier to, and network authentication is to the dependence of network, and is also very unpractical.USB, softdogs such as LPT are encrypted has not only increased cost, and is easier to be followed the tracks of and crack by the people.
Summary of the invention
The object of the present invention is to provide a kind of encryption method of computer system, it can overcome existing defective, and encrypting and decrypting program and BIOS are compiled simultaneously, is embedded among the BIOS with binary mode, avoids dynamically being followed the tracks of, and security is stronger.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of encryption method of computer system, it may further comprise the steps:
A, the password program code compile is stored among the BIOS;
B, BIOS move password program to the Equipment Inspection of computer system and after just exerting finished;
Every computer all can have the firmware of a connection hardware and operating system, we are appellation BIOS, we are the some of encrypting and decrypting program as BIOS, be compiled among the whole BIOS, at BIOS to hardware CPU for example, chipset, and after some Equipment Inspections such as hard disk and initialization finish, rerun our encrypting and decrypting program is to judge whether the being system of validated user.
C, read the hard disk sequence number;
D, judge whether backed up the hard disk sequence number among the BIOS,, enter step h,, enter step e if do not have if having;
E, backup hard disk sequence number are to BIOS;
F, hard disk boot sector and partition table sector are encrypted;
G, restart hardware system, BIOS is re-powered after, operating procedure c then;
Encryption to system is only carried out in female BIOS, female BIOS is meant that firm compiling comes out, also the BIOS that on hardware system, did not move, it some be used for preserving the space of hard disk sequence number, female BIOS start writes this with the hard disk sequence number and partly just becomes behind space and be sub-BIOS, so we we female BIOS can read the sequence number of hard disk earlier when starting shooting, detect simultaneously and whether backed up sequence number, if explanation is not backup for the first time, so current hard disk sequence number is preserved the space of the sequence number that BIOS reserves after by cryptographic calculation, afterwards the boot sector and the partition table sector number a tree name of current hard disk are encrypted, after finishing the encryption of sequence number preservation and hard disk boot sector and partition table sector, restart hardware system.
H, read the hard disk sequence number of BIOS backup;
I, judge whether two hard disk sequence numbers mate,,, enter step j if do not match if coupling enters step k;
J, the wrong shutdown of prompting;
K, deciphering hard-disk system boot sector and partition table sector.
In above-mentioned steps e, current hard disk sequence number is to backup among the BIOS by cryptographic algorithm.
In above-mentioned steps f, its described encryption method is that selected specific character string and data are carried out XOR, and carries out byte shift.
In above-mentioned steps k, it is deciphering hard-disk system boot sector and partition table sector in internal memory.
After adopting said method, because the encrypting and decrypting program all is to compile simultaneously with BIOS, be embedded among the BIOS with binary mode, so the dynamic tracking of having no idea basically to accomplish, so compared with prior art, its security has obvious enhancing than other.

Fig. 1 is a structured flowchart of the present invention.
Embodiment
Please refer to shown in Figure 1ly, the invention discloses a kind of encryption method of computer system, it may further comprise the steps:
A, encryption and decryption program code compiling is stored among the BIOS;
B, BIOS move password program to the Equipment Inspection of computer system and after just exerting finished;
C, read the hard disk sequence number;
D, judge whether backed up the hard disk sequence number among the BIOS,, enter step h,, enter step e if do not have if having;
E, current hard disk sequence number is backuped among the BIOS by cryptographic algorithm;
F, hard disk boot sector and partition table sector are encrypted, its encryption method is that selected specific character string and data are carried out XOR, and carries out byte shift;
G, restart hardware system, BIOS is re-powered after, operating procedure c then;
H, read the hard disk sequence number of BIOS backup;
I, judge whether two hard disk sequence numbers mate,,, enter step j if do not match if coupling enters step k;
J, the wrong shutdown of prompting;
K, in internal memory deciphering hard-disk system boot sector and partition table sector.
Specific embodiment is enumerated in the invention, is not in order to restriction the invention, in not breaking away from the present invention's spirit scope, to those skilled in the art, can do various variations, modification and application, and all this all still belongs to the protection domain of this patent.
