Abstract
The invention discloses a secret key storage method of a wireless fixed telephone. The secret key storage method of the wireless fixed telephone includes the following steps: (1) selecting a first secret key which is used for telephone card authentication and a first encryption algorithm which is used for the telephone card authentication, wherein the telephone card authentication is authentication between a telephone of the wireless telephone and a subscriber identity module (SIM) card, (2) encrypting and writing a code of the first encryption algorithm and the first secret key in a flash by adopting a second encryption algorithm and a second secret key. The invention further discloses a telephone card authentication method of the wireless fixed telephone. Due to the fact that the secret key storage method and the telephone card authentication method of the wireless fixed telephone does not need to be provided with a write-only chip, the secret key storage method and the telephone card authentication method of the wireless fixed telephone solves the problem that the existing wireless fixed telephone needs to be provided with the write-only chip, wherein the write-only chip supports a 3 data encryption standard (DES) algorithm and all operations relative to the secret keys are finished in the chip. The secret key storage method and the telephone card authentication method of the wireless fixed telephone has the advantages of being capable of guaranteeing safety of the secret keys and simultaneously reducing cost of the wireless fixed telephone, and beneficial for development and application of the wireless telephone.
Description
Technical field
The present invention relates to a kind of method for storing cipher key and machine-card authentication method of fixed CDMA WLL, particularly relate to a kind of method for storing cipher key and machine-card authentication method that need not only to write the fixed CDMA WLL of chip.
Background technology
Fixed CDMA WLL is commonly called as " channel radio ", and its outward appearance is the ordinary telephone set outward appearance, is based on a kind of telecom terminal product of GSM/CDMA wireless network.Its core technology adopts the GSM/CDMA mobile communication system, and the number of opening also is phone number, and charge is collected by common local telephone network.Because " fixed CDMA WLL " need not rewiring, can be that operator saves very large expense; Main is, it can get up in " movement ", and this has just greatly enlarged the scope of application of " fixed line "; And along with the further of social informatization gos deep into, " fixed CDMA WLL " will have wide development space as a kind of extension and the expansion of former " telecommunications fixed line ".
Current, the mobile fixed CDMA WLL of having released, what this fixed CDMA WLL used is encrypted card, each start needs the authentication of machine card, the 3DES algorithm of authentication encryption algorithm Application standard (is that DES is to the cryptographic algorithm of AES transition, it uses 3 64 key that data are carried out three encryptions, this algorithm is a safer distortion of DES algorithm), this just is designed into the problem of key storage, generally for key safety, key need to store in the chip of only writing, and this chip is supported the 3DES algorithm, and all operations of being correlated with key are all finished in this chip.So just at the cost that has virtually increased fixed CDMA WLL, be unfavorable for that the expansion of fixed CDMA WLL is used.
Summary of the invention
The technical problem to be solved in the present invention is to be encrypted card for what overcome that fixed CDMA WLL of the prior art uses, and only write chip, defective that cost is higher for the safe storage of key must use, a kind of method for storing cipher key and machine-card authentication method that chip can guarantee the fixed CDMA WLL of secret key safety that need not only to write is provided.
The present invention solves above-mentioned technical problem by following technical proposals:
A kind of method for storing cipher key of fixed CDMA WLL, its characteristics are that it may further comprise the steps:

2, adopt in one second cryptographic algorithm and the code and this first secret key encryption programming to a FLASH of one second key with this first cryptographic algorithm.
Preferably, step S
2Further comprising the steps of:
S
21, adopt one second cryptographic algorithm and one second key with code and this first secret key encryption of this first cryptographic algorithm;
S
22, the first cryptographic algorithm after adopting a compilation tool to encrypt code compilation become an executable file and compile a threaded file, this threaded file is used to specify the operation address of this executable file;
S
23, according to threaded file with this executable file programming to this FLASH.
Preferably, the GPIO interface of the application processor by this fixed CDMA WLL is selected this second key.
Preferably, this first cryptographic algorithm is the 3DES algorithm.
The present invention also provides a kind of machine-card authentication method of fixed CDMA WLL, and its characteristics are, its as described above the method for storing cipher key of fixed CDMA WLL store after the first key and the first cryptographic algorithm, further comprising the steps of:
S
4, fixed CDMA WLL phone start, prepare to carry out the authentication of machine card;
S
5, by this second secret key decryption step S
2Middle programming enters the first key and the first cryptographic algorithm among this FLASH;
