Abstract
The invention provides a breathing machine configuration upgrading method. The method comprises the steps of obtaining a configuration code from a breathing machine to be upgraded; obtaining configuration information from the configuration code, modifying the configuration information according to an upgrading request, and then encrypting the modified configuration information and a time factor to generate a registration code; when the breathing machine is upgraded, comparing the time factor in the registration code with the time factor in the configuration code on the breathing machine, and if comparison is successful, upgrading the breathing machine by means of the registration code. The registration code generated through the method contains the time factor information, and the defect that one registration code achieves configuration upgrading of multiple breathing machines can be effectively overcome; the registration code is generated by means of encryption of a shifting encryption algorithm and is not likely to be decoded.
Description
Technical field
The invention belongs to respirator field, particularly to a kind of configuration upgrade method of respirator.
Background technology
Respirator has a variety of breathing patterns and function on hardware, but according to buying the demand of user, not every pattern and function all can be opened, and when client needs pattern and the function that these do not open, needs the configuration information of respirator to be modified and upgrades.
In order to prevent user from arbitrarily changing the configuration information of respirator, the pattern that Free Acquisition respirator is not opened and function, need the configuration information on every respirator is encrypted.The reliability of current displacement AES is not high, easily decodes.
Content of the invention
It is an object of the invention to when overcoming current respirator to carry out configuration change, the multiple users existing all can change the problem of respirator configuration using a registration code；Propose a kind of configuration upgrade method of respirator, the method is encrypted to registration code based on time factor, using multiple shift AES, increase decoding difficulty, improve safety.
To achieve these goals, the invention provides a kind of configuration upgrade method of respirator, methods described includes: obtains configuration code from respirator to be upgraded；Obtain configuration information from configuration code, and require described configuration information is modified according to upgrading, then the configuration information after change and time factor encryption are generated registration code；When respirator is upgraded, the time factor in the configuration code in the time factor and respirator in described registration code is compared, compare successfully, then using registration code, respirator is upgraded.
In technique scheme, methods described specifically includes:
Step 1) obtain configuration code from respirator to be upgraded；
Step 2) to step 1) configuration code that obtains is decoded, obtains configuration information, and require described configuration information is modified according to upgrading, after the configuration information after change and time factor encryption are generated registration code；
Step 3) to step 2) registration code that obtains rejects the random number adding, then find the number of times of encryption, it is decoded obtaining three unit code；
Step 4) judge step 3) whether the three unit code that obtains identical with the time factor in the configuration code of described respirator；If a determination be made that certainly, proceed to step 5)；Otherwise, proceed to step 6)；
Step 5) to step 3) three unit code that obtains is encrypted, obtains encrypted code, and preserved, upgrade successfully；
Step 6) this respirator can not be carried out with configuration upgrading.
In technique scheme, described step 1) specifically include:
Step 101) read described respirator encrypted code；
Step 102) to step 101) encrypted code that obtains is decoded obtaining the first true form, and obtain the configuration information of described respirator from the first true form；
Step 103) with time factor and configuration information for the second true form, based on displacement AES, the second true form is encrypted, wherein encryption number of times is a random number, thus obtains the configuration code of described respirator.
In technique scheme, described step 2) specifically include:
Step 201) to step 103) configuration code that obtains is decoded obtaining described second true form；
Step 202) configuration information in modification the second true form is required according to upgrading；
Step 203) amended second true form is encrypted, wherein encryption number of times is a random number；The second true form after being encrypted；
Step 204) according to step 203) the second true form after the encryption that obtains, encryption number of times and a generating random number registration code.
In technique scheme, described three unit code is amended second true form.
It is an advantage of the current invention that:
1st, the configuration upgrade method of respirator of the present invention can effectively prevent the registration code from realizing the defect of multiple stage respirator configuration upgrading；
2nd, the registration code of the present invention is to be generated it is not easy to be decrypted using displacement AES encryption.
3rd, the method for the present invention adopts multiple shift to encrypt, that is, according to being which time encryption, using the corresponding code table of different displacements.Increase decoding difficulty, improve safety.
