Abstract
The invention provides a method for protecting a mobile terminal and the data service message thereof, wherein, the mobile terminal comprises a pair of public key and private key certificates. The method comprises the following steps: the data service message encrypted by the private key certificate and sent by a sending end is received; the information header of the data service message comprises a device identity code of the sending end; and whether the public key certificate of the sending end exists is found out according to the device identity code, and if yes, the public key certification is used for decrypting the data service message. By the method, a receiver which the sending end does not trust can not read an MMS or an EMAIL even if the receiver receives the MMS or the EMAIL; and by processing the data service message and a common message separately, necessary protection for the important message is provided, and the efficiency in sending the common message is guaranteed as well.
Description
Technical field
The present invention relates to a kind of portable terminal and data processing method thereof, relate in particular to a kind of portable terminal data service message guard method and adopt the portable terminal of this method.
Background technology
Existing portable terminal is supported multiple type of message based on data service, for example: note, multimedia message (MMS) and Email (EMAIL) etc.And now a lot of portable terminals are all supported the DRM2.X business, and in the case, each mobile phone all has unique device certificate, can uniquely identify this mobile phone.
Wherein DRM is called digital copyright management, and being divided into two classes, one class is the multimedia protection, for example encrypts film, music, audio frequency and video, files in stream media.An other class is an encrypted document, Word for example, Excel, PDF etc.
The operation principle of digital copyright management is; at first set up the digital program authorization center; digital program content after the encoding compression utilizes key (Key) can encryptedly to protect (lock), and the digital program head of encryption is being deposited the network address of key identification (KeyID) and program authorization center.The user according to the key identification of program head and the website information of program authorization center, just can send relevant secret key decryption after the checking mandate by the digital program authorization center in a sowing time, and program can be play.
The program that needs protection is encrypted, even preserved by user's download, the checking mandate that does not obtain the digital program authorization center also can't be play, thereby has protected the copyright of program closely.
(Public Key Infrastructure PKI) realizes DRM by public certificate mechanism.PKI is a kind of key management platform of following set standard, it can use cryptographic service and necessary key and certificate management systems such as encryption and digital signature are provided for all-network, in simple terms, PKI is exactly the infrastructure that security service is provided of utilizing the PKI theory and technology to set up.The PKI technology is the core of information security technology, also is the key and the basic technology of ecommerce.
The DRM agreement can protect receiving terminal not transmit MMS and EMAIL, but if because user misoperation is sent out MMS or EMAIL has misused the family and just can not guarantee that receiving terminal can't open MMS or EMAIL.For example, user A can issue B to a DRM file by multimedia message, and B can utilize DRM module in the mobile phone and browser to go online to obtain copyright and re-use.If but user A is write the multimedia message recipient as C because of carelessness, C re-uses after can utilizing DRM module in the mobile phone and browser to go online to obtain copyright equally.Thereby existing mobile DRM technology still exists potential safety hazard.
Summary of the invention
The purpose of the embodiment of the invention is to provide the guard method of a kind of portable terminal and data service message thereof, thereby raising is to the fail safe of the data service message of portable terminal and the confidentiality of service data service message.
The embodiment of the invention provides a kind of guard method of data service message of portable terminal, wherein said portable terminal comprises that PKI and private key certificate are right, this method comprises: receiving end/sending end send with private key certificate ciphered data service message, comprise the device identity code of described transmitting terminal in the information header of described data service message; Search the public key certificate that whether has described transmitting terminal according to described device identity code,, then decipher described data service message with this public key certificate if having.
Described device identity code is the cryptographic Hash of the public key certificate of transmitting terminal.
In a preferred embodiment, also comprise step: transmitting terminal judges whether message to be sent is non-data service message, if then without private key certificate message is signed.
In a preferred embodiment, also comprise step: whether comprise device identity code in the information header of receiving terminal detect-message; If comprise described device identity code, then search the public key certificate that whether has described transmitting terminal according to described equipment identities identification code, if having, then utilize described public key certificate to decipher described data service message and open message file; If do not comprise described device identity code, then directly open message file.
In a preferred embodiment, also comprise step: to the public key certificate of the described transmitting terminal of described transmitting terminal request.
The embodiment of the invention also provides a kind of portable terminal, this portable terminal comprises at least: receiver module, be used for the usefulness private key certificate ciphered data service message that receiving end/sending end sends, the device identity code that comprises described transmitting terminal in the information header of described data service message, deciphering module, be used for searching the public key certificate that whether has described transmitting terminal,, then decipher described data service message with this public key certificate if having according to described device identity code.
In a preferred embodiment, also comprise: sending module, be used for sending with private key certificate ciphered data service message, comprise device identity code in the information header of described data service message.
In a preferred embodiment, also comprise: memory module is used to store the PKI of this portable terminal and the private key certificate public key certificate to, other portable terminals.
In a preferred embodiment, also comprise: judge module, be used to judge whether message to be sent is data service message, if, then this portable terminal with private key certificate ciphered data service message, otherwise message is signed without the private key certificate of this portable terminal.
In a preferred embodiment, also comprise: control module is used for utilizing the PKI of memory module and private key certificate that the data service message of transmission/reception is controlled described portable terminal described data service message is carried out encrypt/decrypt.
Wherein, described device identity code is the cryptographic Hash of the public key certificate of this portable terminal.
Wherein, described data service message is short message, Multimedia Message or Email.
Pass through the embodiment of the invention; even make the mistrustful recipient of transmitting terminal receive MMS or EMAIL also can't read MMS and EMAIL; and pass through data service message and common message differentiating and processing; both important messages is carried out necessary protection, guaranteed the transmitting efficiency of common message again.
