Abstract
The invention discloses a software encryption method and relates to software, in particular to a software encryption method for an electronic terminal product. The method comprises the following steps that: a personal computer (PC) tool uses a unique identification number of a central processing unit (CPU ID) as a plaintext and uses a key to encrypt the plaintext by selecting an encryption algorithm to obtain a group of ciphertext 1; when performing dial-up networking, the terminal product invokes an encryption process of an embedded terminal and acquires a group of random numbers as the key by using the same product number as an index and by using the same encryption algorithm to encrypt the CPU ID, namely the plaintext to obtain another group of ciphertext 2; and the ciphertext 1 is compared with the ciphertext 2, if the ciphertext 1 is as same as the ciphertext 2, decryption is performed successfully, and if the ciphertext 1 is different from the ciphertext 2, the terminal cannot be used. The method has the advantages of encrypting the product software and preventing the software from being acquired illegally by using the simple and readily-implemented pure software encryption method, preventing serial board among the product software, not adding other hardware equipment and reducing the cost of the product.
Description
Technical field
The present invention relates to software, relate in particular to a kind of software enciphering method of electronic terminal product.
Background technology
In traditional design, end product software cryptography is the mode that combines by software and hardware, and the mode of software combined with hardware need use the IC chip, has increased the cost of product.
Summary of the invention
Technical matters to be solved by this invention provides a kind of simple software encryption method; can effectively encrypt the software of electronic terminal product such as card of surfing Internet; both can protect product software not by illegal obtaining, also can prevent the string plate between different software simultaneously.
The present invention is achieved through the following technical solutions: a kind of software enciphering method comprises the following steps:
The PC tool ends end issues AT and instructs embedded end, obtains the production number and the unique identifier (CPU ID) of CPU of end product;
The PC tool ends end is a plaintext with the unique identifier of CPU (CPU ID), obtains one group of random number as key according to production number, chooses a kind of cryptographic algorithm and with key plaintext is encrypted, and obtains one group of ciphertext 1;
The PC tool ends end is kept at ciphertext 1 in the internal memory (eeprom) of end product by issuing the AT order again;
When end product can call the encryption flow of embedded end when dialling up on the telephone, use identical cryptographic algorithm, with identical production number be index to obtain one group of random number be key, the identifier unique to CPU (CPUID) promptly expressly encrypted, and obtains another group ciphertext 2;
Ciphertext 1 and ciphertext 2 are compared, if two ciphertexts are identical, successful decryption can the normal dialing online, if different, and software reset then, terminal can't be used.
Below above technical scheme is further elaborated:
Further comprising the steps of to the different embedded software of production number in same equipment:
Same equipment, elder generation's programming production number is 1 embedded software, and through after the encryption of tool software, embedded end uses identical production number and the unique identifier (CPU ID) of CPU to encrypt with the PC tool ends end, the encrypted result that obtains is identical, can connect by proper network;
Reburning, to write production number be 2 embedded software, and the unique identifier (CPU ID) of CPU is identical, but the production number difference, the encrypted result difference of gained can not connect network.
Beneficial effect of the present invention is: adopt a kind of pure software cipher mode of realizing of simply being easy to, both can encrypt product software, prevent that software is illegally accessed, also can prevent simultaneously the string plate between different product software, and do not need to add other hardware device again, reduced the cost of product.
Description of drawings
Fig. 1 is software realization flow figure of the present invention.
Embodiment
The present invention will be further described below in conjunction with drawings and Examples:
As shown in Figure 1, the PC tool ends end issues AT and instructs embedded end, obtains the production number and the unique identifier (CPU ID) of CPU of end product; The PC tool ends end is a plaintext with the unique identifier of CPU (CPU ID), obtains one group of random number as key according to production number, chooses a kind of cryptographic algorithm and with key plaintext is encrypted, and obtains one group of ciphertext 1; The PC tool ends end is kept at ciphertext 1 in the internal memory (eeprom) of end product by issuing the AT order again; When end product can call the encryption flow of embedded end when dialling up on the telephone, use identical cryptographic algorithm, with identical production number be index to obtain one group of random number be key, the identifier unique to CPU (CPU ID) promptly expressly encrypted, and obtains another group ciphertext 2; Ciphertext 1 and ciphertext 2 are compared, if two ciphertexts are identical, successful decryption can the normal dialing online, if different, and software reset then, terminal can't be used.Adopt this pure software cipher mode that is simple and easy to and realizes, can encrypt, prevent that software is illegally accessed, and do not need to add other hardware device again, reduced the cost of product product software.
In same equipment be: same equipment to the different embedded software of production number, elder generation's programming production number is 1 embedded software, through after the encryption of tool software, embedded end uses identical production number and the unique identifier (CPU ID) of CPU to encrypt with the PC tool ends end, the encrypted result that obtains is identical, can connect by proper network; Reburning, to write production number be 2 embedded software, and the unique identifier (CPU ID) of CPU is identical, but the production number difference, the encrypted result difference of gained can not connect network.Can prevent the string plate between different product software like this,
Below be a kind of embodiment of the present invention:
The production number of end product is 0 in this implementation method, the unique identifier (CPU ID) of CPU is " 1234567890123456 ", with production number 0 is that index obtains a group key for " 11223344556677889900112233445566 ", the PC tool ends end uses the 3des algorithm to obtain one group of ciphertext 1 " 1234567890abcdef " with key to expressly encrypting, and preserves ciphertext 1 in the internal memory (eeprom) of end product by issuing the AT instruction.End product calls the encryption flow of embedded end when dialling up on the telephone, use identical cryptographic algorithm, be that to obtain one group of random number be key to index with the production number, the identifier unique to CPU (CPU ID) promptly expressly encrypted, obtain another group ciphertext 2 " 1234567890abcdef ", ciphertext 1 and ciphertext 2 are compared, and equate, can dial up on the telephone normally.
End product is earlier after the PC instrument is encrypted in this implementation method, reburning, to write production number be 1 software version, product calls Embedded encryption flow when dialling up on the telephone, embedded end obtains a group key with production number 1 and is " 11223344556600112233445566778899 ", use the 3des algorithm, with this key plaintext " 1234567890123456 " is encrypted, obtain one group of ciphertext 3 " abcdef1234567890 ", ciphertext 3 and ciphertext 1 are relatively, because production number, so the encrypted result difference, deciphering failure, software reset.Therefore, prevented string plate between different software.
The announcement of book and instruction according to the above description, those skilled in the art in the invention can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the embodiment that discloses and describe above the present invention is not limited to also should fall in the protection domain of claim of the present invention modifications and changes more of the present invention.In addition, although used some specific terms in this instructions, these terms do not constitute any restriction to the present invention just for convenience of description.
