Method is encrypted, and in an embodiment of the present invention, second encryption method includes but not limited to AES encryption method.
That is, using the encryption key, the data transmitted to needs by AES encryption method are encrypted, so
Encrypted data are transmitted again afterwards.
During above-mentioned steps S101~step S105, plaintext secret key is added by base64 Encryption Algorithm
It is close, obtain encryption secret key, then using the encrypted encryption secret key of base64 Encryption Algorithm by AES encryption method to needing to pass
Defeated data are encrypted, that is to say, that during data transmission, complicate encrypted need to transmit to the greatest extent
Data, need the data transmitted and the encryption direct relationship of secret key, reach maximized mixed using nonlinear transformation algorithm
Confuse.Further, plaintext secret key and encryption secret key often change one and will maximumlly influence the digit in encrypted data,
Maximized diffusion is reached using linear transformation algorithm.
The embodiment of the present invention additionally provides a kind of data transmission method, specifically, as shown in figure 3, Fig. 3 is that the present invention is another
The flow chart of data transmission method in embodiment.The data transmission method includes：Data sending terminal is using encryption secret key with the
The data that two encryption methods transmit needs are encrypted, and send encrypted data, wherein the encryption secret key is to pass through
The encryption of first encryption method obtains；Such as the step S301 in Fig. 3；Data receiver is after receiving encrypted data, profit
Encrypted data are decrypted described in the encryption secret key pair, such as the step S303 in Fig. 3.
Step S301, data sending terminal are added using encryption secret key with the data that the second encryption method transmits needs
It is close, and send encrypted data.
First, data sending terminal obtains encryption secret key.Specifically, the data sending terminal obtains the mistake of the encryption secret key
Journey includes：Generate plaintext secret key；The plaintext secret key is encrypted using first encryption method, it is secret to obtain pre-encrypt
Key；The data of presetting digit capacity are obtained from the pre-encrypt secret key；According to the data of the presetting digit capacity, it is secret to obtain the encryption
Key.Then the pre-encrypt secret key is written in configuration file, and the configuration file is transmitted to the smart home device
Each terminal device in the network of composition.
Specifically, in an embodiment of the present invention, first encryption method includes but not limited to base64 Encryption Algorithm.
Base64 Encryption Algorithm is to be used for transmission the coding mode of 8Bit bytecodes.In other embodiments of the present invention, described first adds
Decryption method can also be other encryption methods, such as can also be DES (Data Encryption Standard, data encryption
Standard) or 3DES (Triple DES, triple data encryption algorithm) encryption method.
Then, the data of presetting digit capacity are obtained from the pre-encrypt secret key.
Specifically, the presetting digit capacity is 2NPosition, wherein N is the integer more than or equal to 6.That is from described pre-
2 are obtained in encryption secret keyNPosition data.In an embodiment of the present invention, N values are 6, i.e., obtain 64 from the pre-encrypt secret key
Position data.Certainly, in other embodiments of the invention, the presetting digit capacity can also be 128,256 or other positions
Several data.Certainly with the increase of the presetting digit capacity, according to described 2NThe encryption secret key that position data are formed just is increasingly difficult to
To crack, data transmission is safer, but the consumption coded and decoded to data is with regard to increasing, therefore can basis
Actual conditions carry out assessment selection, such as in an embodiment of the present invention, and 64 data are obtained from the pre-encrypt secret key.
Finally, according to the data of the presetting digit capacity, the encryption secret key is obtained.
