Abstract
The invention discloses an encrypted programming method. The encrypted programming method includes the steps of S1, binding a program package with an encrypted password package and transmitting the bound packages to a microprocessor; S2, electrically connecting a target chip with the microprocessor prior to that the target chip generates a request signal; S3, enabling a power management module to receive the request signal and switch a working voltage into a working voltage required by the target chip according to the request signal; S4, enabling the microprocessor to write a serial port data module into the target chip or store the serial port data module to a storage chip before writing the serial port data module into the target chip, and setting a validation password; S5, when the target chip is updated, inputting the validation password and a download password, keeping the validation password unchanged if the validation password is consistent with the download password, changing the validation password into the download password if the validation password is inconsistent with the download password, and canceling the validation password if the download password is not set. The encrypted programming method has the advantages that updating can be completed when the validation password is consistent with the download password, a validation password for next target chip updating is determined according to the download chip, and accordingly, the encrypted programming method is more convenient.
Description
Technical field
The present invention relates to a kind of encryption programmed method.
Background technology
Along with the development of science and technology, electronic product is more and more universal.In prior art, be generally program is write in objective chip to use for electronic product, in the process of programming, routine package do not encrypted, easily leak original program during later stage ROMPaq or malice is carried out to original program and distort, cause serious economic loss.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of encryption programmed method.
In order to achieve the above object, technical scheme of the present invention is as follows:
The invention provides a kind of encryption programmed method, comprise the following steps:
S1, routine package and encrypted ones bag being bound and to write in serial port module, routine package and encrypted ones bag are converted to serial data and send microprocessor to by serial port module;
S2, objective chip is electrically connected with microprocessor after generate request signal by objective chip;
S3, power management module receive request signal and according to this request signal, operating voltage are switched to the operating voltage of objective chip needs;
Serial data module writes in objective chip or writes in objective chip after being stored to storage chip again by S4, microprocessor, arranges verification password simultaneously;
When routine package in S5, objective chip upgrades, input validation password and download password, if it is consistent with verification password to download password, then password is not changed; If it is inconsistent with verification password to download password, then verify password change for downloading password; If do not arrange download password, then cancel verification password.
When in the present invention, objective chip upgrades, need input validation password, password unanimously just can complete the renewal of program, download password is set simultaneously, the verification password of objective chip renewal is next time determined according to the facilities downloading password, different verification passwords is set, also can cancels verification password, convenient.
On the basis of technique scheme, also can do following improvement:
As preferred scheme, in above-mentioned step S5 during input validation password, if password authentication mistake once, then password number of times limiting module reduces accordingly or increases once, until the limited number of times of password number of times limiting module is zero or limits number of times.
Adopt above-mentioned preferred scheme, password number of times limiting module can limit the number of times of verification password, safer.
As preferred scheme, if the limited number of times of password number of times limiting module be zero or limit number of times time, hummer send yowl and by objective chip more New function forever close.
Adopt above-mentioned preferred scheme, exceed the limited number of times i.e. permanent more New function of closing objective chip of password number of times limiting module, avoid malicious downloading, safer.
Embodiment
The following detailed description of the preferred embodiment of the present invention.
In order to reach object of the present invention, a kind of encryption programmed method being provided in wherein a kind of embodiment of the present invention, comprising the following steps:
S1, routine package and encrypted ones bag being bound and to write in serial port module, routine package and encrypted ones bag are converted to serial data and send microprocessor to by serial port module;
S2, objective chip is electrically connected with microprocessor after generate request signal by objective chip;
S3, power management module receive request signal and according to this request signal, operating voltage are switched to the operating voltage of objective chip needs;
S4, microprocessor write after serial data module stores to storage chip in objective chip again, arrange verification password simultaneously;
When routine package in S5, objective chip upgrades, input validation password and download password, if it is consistent with verification password to download password, then password is not changed; If it is inconsistent with verification password to download password, then verify password change for downloading password; If do not arrange download password, then cancel verification password.
When in present embodiment, objective chip upgrades, need input validation password, password unanimously just can complete the renewal of program, download password is set simultaneously, the verification password of objective chip renewal is next time determined according to the facilities downloading password, different verification passwords is set, also can cancels verification password, convenient.
In order to optimize implementation result of the present invention further, in another embodiment of the invention, on the basis of foregoing teachings, in above-mentioned step S5 during input validation password, if password authentication mistake once, then password number of times limiting module reduces accordingly or increases once, until the limited number of times of password number of times limiting module is zero or limits number of times.
Adopt above-mentioned preferred scheme, password number of times limiting module can limit the number of times of verification password, safer.
In order to optimize implementation result of the present invention further, in another embodiment of the invention, on the basis of foregoing teachings, if the limited number of times of password number of times limiting module be zero or limit number of times time, hummer send yowl and by objective chip more New function forever close.
Adopt above-mentioned preferred scheme, exceed the limited number of times i.e. permanent more New function of closing objective chip of password number of times limiting module, avoid malicious downloading, safer.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, and without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
