Along with the application of note in the business procedure more and more widely, the safety problem of note will be much accounted of day by day.Many cell phone manufacturers are at head it off, and as note password read or hiding SMS are set for mobile phone, but these methods are cured the symptoms, not the disease.Because the note on the mobile phone all sends by the text plain mode at present, this divulges a secret very risky concerning the note that security information is arranged, because the signal of mobile phone all is aerial transmission, can intercept and capture by technological means, as duplicating any note of collecting this number under the situation that is stuck in line by the mode of duplicating SIM card.This is to having produced great threat by mobile phone transmitter confidential information.The best way is the content-encrypt that mobile phone is sent, though like this note in communication process by illicit interception, be not afraid of yet and divulge a secret.
Summary of the invention
Purpose of the present invention, just provide a kind of cellphone information encryption method, the user can encrypt send short message content, and whether is provided with password according to target mobile phones and is target mobile phones transmission encrypting information or cleartext information automatically, realizes having only the target of note to receive mobile phone and could read this information.
Technical scheme of the present invention is as follows:
A kind of cellphone information encryption method, comprise receiving terminal, send terminal and information centre, it is characterized in that, comprise encrypting and decrypting assembly and key synchronization module in described receiving terminal, the transmission terminal, described information centre comprises key receiver module and encrypting and decrypting assembly, its feature also is, may further comprise the steps:
Step 1: receiving terminal, transmission terminal connect by the key receiver module of described key synchronization module and user identification code and described information centre;
Step 2: after connecting, receiving terminal, to send terminal be its interior described encrypting and decrypting module sets key by described key synchronization module, and the encrypting and decrypting component synchronization key in information centre of being connected by described key synchronization module and described information centre key receiver module foundation;
Step 3: described information centre receives from sending terminal information, and described transmission terminal information encrypting and decrypting assembly in described transmission terminal is sent to information centre after becoming ciphertext by secret key encryption;
Step 4: described information centre receives from indicating pairing secret key decryption one-tenth expressly according to sending the terminal use after the enciphered message that sends terminal, indicates according to the receiving terminal user then and is sent to receiving terminal after pairing secret key encryption becomes ciphertext;
Step 5: described receiving terminal according to the key of its encrypting and decrypting assembly to receive that adding ciphertext is decrypted expressly the back to read.
Described receiving terminal, send terminal and comprise with the mode that information centre connects, note connects, GSM connects, GPRS connects, CDMA connects and 3G connects, a kind of in the computer network connection.
Described receiving terminal, the encrypting and decrypting assembly that sends terminal are a kind of in encryption software or the encrypted circuit.
Described encrypting and decrypting assembly is PKI/secret key encryption manner of decryption or single password encrypting and decrypting mode.
Characteristics of the present invention and advantage:
1, whether receiving terminal, transmission terminal can be provided with as required to need to encrypt and send note, and can change key at any time.
2, need not to notify the receiving terminal decruption key after the transmission terminal is set key.
3, information centre carries out encrypted transmission according to the set key of receiving terminal automatically, if then plain code transmission of key is not set, the user need not to do any manual operation.
4, the whole system principle is simple, and it is convenient, with low cost to realize.
Description of drawings
