Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention is clearer, describe in further detail below in conjunction with accompanying drawing.
Fig. 1 is the method flow diagram of software systems bootstrapping in first preferred embodiment of the present invention.Present embodiment may further comprise the steps:
This electricity for the treatment of that the burning memory can be above-mentioned communication terminal is wiped non-volatile type memorizer, memories such as hard disk.
Explanation above-mentionedly treats that the burning program for the treatment of of the first characteristic information correspondence of burning program is not by the clean program of unauthorized amendment once more.This treats that the burning program and first characteristic information produced, and promptly needed to pre-determine first characteristic information for the treatment of burning program before execution in step 101 before software systems are carried out bootstrapping.Fig. 2 is the first embodiment flow chart that pre-determines the first characteristic information process for the treatment of burning program, and this process may further comprise the steps:
In this step, first characteristic information can be a message digest value for the treatment of burning program.Wherein, message digest value is a kind of characteristic value of program.Message digest value is widely used in the numeric security field as a kind of digital finger-print.The algorithm that calculates message digest value can be Hash (hash) algorithm commonly used, message authentication code (MAC) algorithm, perhaps simple CRC (CRC) algorithm etc. comparatively.Certainly, also can adopt other algorithms to calculate message digest value.
In this step, first characteristic information for the treatment of burning program can also be to treat burning program through after the encryption, the encrypted message digest value for the treatment of burning program.
In the practical application, first characteristic information also can corresponding to other forms of, through as the operation deformation process of encrypting and so on after treat burning program.
After further guaranteeing to treat that burning program can be by unauthorized amendment, also can treat the burning program or first characteristic information to do further deformation process, write in the random access memory again.Deformation process can be: encrypt first characteristic information; Perhaps encrypt first characteristic information, and encrypt and treat burning program; Perhaps encrypt this and treat burning program, or the like.
Wherein, treat burning program or first characteristic information encrypted to adopt symmetric cryptography method or asymmetric encryption method.When utilizing symmetric encryption method, can adopt root key to encrypt.Root key can comprise hardwired root key and disposable programmable (OTP) root key, or the key of realizing by other technology that can not change.Root key is a kind of key that is retained in communication terminal inside, owing to this key is stored at the communication terminal chip internal, and does not have line with the external world, therefore can not read from communication terminal by any way.Like this, just further guarantee the fail safe of encrypted content.For the software provider who utilizes root key to encrypt, this software provider may grasp the telecom terminal product design side of this root key technology exactly, or the partner of this telecom terminal product design side, therefore, can obtain the root key technology from telecom terminal product design side, perhaps directly finish cryptographic operation by telecom terminal product design side.If utilize root key to encrypt, so accordingly, when deciphering, need utilize this root key to be decrypted.When adopting asymmet-ric encryption method, can utilize the above-mentioned private key for the treatment of that the burning program provider provides to encrypt.When deciphering, need to utilize the PKI corresponding with this private key to be decrypted so, this PKI also need be by treating that burning program bag provider provides.When utilizing encrypted private key, also need the PKI corresponding with this private key also put into and treat the burning program bag, and can do encryption PKI, treat the fail safe of burning program bag with raising.
Set up above-mentioned when treating burning program, if treat that burning program can be split as a plurality of subprograms.Can move the precedence of these subprograms according to after treating that burning program is by burning, layout first subprogram, second subprogram ..., to last subprogram of forming program.Fig. 3 is the second embodiment flow chart that pre-determines first characteristic information for the treatment of burning program.This process may further comprise the steps:
In this step, can be after burning program be treated in foundation, treat burning program and split to handle and obtain each subprogram.
Step 302, read clean subprogram successively, the clean subprogram that is read is determined first characteristic information of current clean subprogram as current clean subprogram.
Determine in this step each clean subprogram first characteristic information explanation can referring in the step 202 to the explanation of first characteristic information of determining to treat burning program.
As needs, also can be to each clean subprogram in the step 302, or first characteristic information of clean subprogram writes in the communication terminal chip after doing further encryption deformation process.
Fig. 4 is the method flow diagram of communication terminal system bootstrapping in the present invention's second preferred embodiment.This embodiment may further comprise the steps:
This step is finished by the mutual control program in the read-only memory that starts communication terminal.Treat that when communication terminal system detects the burning memory content for empty, just enters this interactive command state, go to the bootstrapping operation of communication terminal system.
Above-mentioned steps 401 is the preceding preparation of bootstrapping flow process of existing communication terminal system with step 402.
Read step 403, the random access memory in communication terminal and treat burning program.
The burning program for the treatment of that writes the communication terminal chip in advance is clean program, in case after this clean program is written into, just exist by unauthorized amendment may.Therefore, also need this is treated that burning program does detection.
Step 404, determine to treat second characteristic information of burning program.
In this step, the same way that need take to determine in the above-mentioned steps 202 to treat first characteristic information of burning program determines to treat second characteristic information of burning program.That is,
If treating first characteristic information of burning program is the message digest value for the treatment of burning program that adopts hash algorithm to calculate, so when determining to treat second characteristic information of burning program, also need to adopt hash algorithm to recomputate and draw the message digest value for the treatment of burning program, this message digest value is to treat second characteristic information of burning program.If treating first characteristic information of burning program is the encrypted message digest value for the treatment of burning program that adopts the CRC algorithm computation to draw, this treats that burning program encrypted by the root key of communication terminal inside, so when determining to treat second characteristic information of burning program, also need to adopt the CRC algorithm to recomputate and draw the encrypted message digest value for the treatment of burning program, this message digest value is to treat second characteristic information of burning program, certainly, treat that burning program is by the same root key encryption of same communication terminal inside.
If treat that second characteristic information of burning program is identical with first characteristic information for the treatment of burning program, then decidable is treated burning program not by unauthorized amendment, is clean program.If treat second characteristic information of burning program and treat that first characteristic information of burning program is inequality, decidable is treated burning program by unauthorized amendment so, poor stability.
Determine second characteristic information based on adopting the way identical with determining first characteristic information, like this, first characteristic information and second characteristic information just have comparativity, otherwise, even communication terminal is treated to treat that burning program is not by unauthorized amendment in the burning program bag, owing to determine that the way of first characteristic information is different with the way of determining second characteristic information, also cause shortage comparativity between these two characteristic informations and can't judge and treat that whether burning program is by unauthorized amendment.As, first characteristic information is the message digest value for the treatment of burning program that adopts hash algorithm to calculate, and second characteristic information is the message digest value for the treatment of burning program that adopts the message authentication code algorithm computation to draw, first characteristic information and second characteristic information that draw like this are normally inequality, do not have comparativity between the two.
Fig. 5 is the method flow diagram of communication terminal system bootstrapping in the present invention's the 3rd preferred embodiment.Wherein, being split as at least one subprogram if be written into the burning program for the treatment of of the memory in the communication terminal, is the mini system program as first subprogram, and this mini system program can comprise: the Memory Controller initialize routine, other communication interface drivers, CPU operating frequency lifting program etc.Second subprogram is an operating system, and the 3rd subprogram is an application program, etc.Wherein, also first subprogram can be continued to be split as a plurality of subprograms.This embodiment may further comprise the steps:
In this step, the same way of first characteristic information that need take in the above-mentioned steps 302 to determine the clean subprogram of current subprogram correspondence is determined second characteristic information of current subprogram.
First characteristic information of the clean subprogram that second characteristic information of step 505, more current subprogram is corresponding with current subprogram judges whether both are identical, if identical, execution in step 506; Otherwise, execution in step 507.
In this step, if first characteristic information is identical with second characteristic information, then current subprogram is clean subprogram, otherwise current subprogram may be by unauthorized amendment, poor stability.
The processing that legalizes can be to search this program to be damaged part and to do repair process; Perhaps, remove the virus that is introduced in this program, repair this program, or the like, these treatment technologies that legalize all can adopt existing technology.
In this step, also execution in step 502 not.For further guaranteeing the fail safe of software systems bootstrapping, can directly withdraw from this bootstrapping process.
