The method comprises the following steps of: receiving target data from first equipment; acquiring a first password, wherein the first password is preset and pre-stored; authenticating the first password; and when the password is valid, storing the target data. Due to the adoption of the invention, the requirement for synchronous data transmission is met, operation of removing a password authentication mechanism for a motherboard of each security architecture is eliminated, the work load is reduced, and the cost is lowered; and moreover, any storing operation for the target data requires password authentication, so that the scheme provided by the embodiment of the invention is very secure.
Description
Technical field
The present invention relates to field of computer technology, be meant a kind of method, device and a kind of computer of simultaneous interpretation data especially.
Background technology
In various computer lab management, be indispensable demand to the protection and the simultaneous interpretation of cmos data, solved the simplified deployment problem of user's cmos data by simultaneous interpretation to cmos data.
CMOS (Complementary Metal Oxide Semiconductor) original idea is meant cmos memory, it is the raw material that a kind of large-scale application is made in integrated circuit (IC) chip, in computer realm, CMOS is the read-write RAM chip of on the computer motherboard, is mainly used to preserve the hardware configuration of current system and the operating personnel setting to some parameter.No matter CMOS RAM chip by a backup battery power supply, is in off-mode by system therefore, still runs into system's power-down conditions, and cmos data can not lost.
So-called CMOS simultaneous interpretation function is meant, with the cmos data on the computer, gives other computers by Network Transmission, and covers its cmos data, finishes the deployment of machine room.
At present, there is a kind of mainboard, as Extensible Firmware Interface (EFI) mainboard, for the mainboard of this type, because the existence of password authentification mechanism can not be supported CMOS simultaneous interpretation function based on the safety framework.And, safeguard a kind of BIOS that removes password authentification mechanism separately for software in order to allow such mainboard can realize CMOS simultaneous interpretation function.
Based on above-mentioned change, the method for existing realization CMOS simultaneous interpretation function is as follows:
Port (as 70,72 ports) by the mainboard appointment reads cmos data, gives other computers by Network Transmission then; On other computers, write by designated port again, cover the cmos data of described other computers fully, thereby realize the simultaneous interpretation of CMOS.
There are the following problems at least for the method for existing realization CMOS simultaneous interpretation function:
1) can to realize CMOS simultaneous interpretation function in order allowing based on the mainboard of above-mentioned security architecture, must all to remove the operation of password authentification mechanism to every mainboard, workload is very big, and the cost height;
2) if 70,72 ports such as grade do not exist or do other purposes, thereby existing scheme is irrealizable fully for the mainboard that does not have later ports such as 70,72.
3) for the mainboard based on the safety framework, its original idea is that any modification to cmos data all needs password authentification, but the password authentification mechanism that existing scheme shields fully, thereby this scheme also is unsafe.
Summary of the invention
