[0001] PROGRAM SOURCE CODE DISTRIBUTING SYSTEM AND METHOD THEREOF [0002]

The present invention relates to a program source downloading system and method for distributing a program of a mobile communication terminal in a source code form instead of a binary code.

As is well known, the mobile communication industry is growing day by day, and the number of mobile communication subscribers is increasing in domestic as well as worldwide. In this situation, with the development of mobile communication technology, interest in wireless Internet has been increasing more and more recently, wireless Internet communication can be used anytime and anywhere by using a terminal represented by a cellular phone, a PCS, a PDA or the like.

Accordingly, the development of the wireless Internet has a great influence on various program industries. Recently, as a download platform for terminals such as a virtual machine (VM), a Brew, and a WinCE has been developed, Have been downloaded and available.

In this software distribution process, the content download server compiles the program source code and converts it into an executable binary file, and then provides the download service to the terminal. Therefore, a separate binary conversion server infrastructure is generated, Not only complicated, but also compile optimization optimized for the terminal's VM is not performed, which slows down the program execution speed.

In addition, according to the conventional program downloading method, since downloading is permitted without installing a separate security system when an application program is downloaded, security incidents such as illegal downloading and illegal copying are incurred, There was a following problem.

It is an object of the present invention to simplify the structure of a software download system by eliminating a separate binary conversion server infrastructure, and to improve compilation and security.

According to another aspect of the present invention, there is provided a program source download system including: a content portal server for providing a program purchase service;

A content download server for receiving identification information of a purchased program and authentication information of a terminal purchasing the program from the content portal server and encrypting a source of the program corresponding to the identification information; And

And a terminal for transferring authentication information to the content portal server and downloading the encrypted program source from the content download server, decrypting and compiling the encrypted program source, and converting the encrypted program source into an executable file.

According to another aspect of the present invention, there is provided a method for downloading a program source, the method comprising the steps of: after a terminal selects a program, transmitting authentication information to a content portal server;

Receiving the authentication information and the program identification information of the terminal from the content portal server, encrypting the program source using the authentication information of the terminal, and transmitting the encrypted program source to the terminal; And

The terminal downloads an encrypted program source from the content download server, decrypts, compiles and converts the encrypted program source into an executable file.

According to the present invention, when the application program is downloaded, the program source code itself is provided to the terminal, and the program source code is XML encrypted using the terminal information such as the telephone number or the UUID information of the terminal, thereby providing a separate binary conversion server infrastructure To optimize the structure of the program download system and to improve the program security system accordingly,

In terms of the terminal, since the application source code itself is downloaded and the program is executed after compiling itself, the execution speed of the VM-based program is remarkably improved.

Hereinafter, a configuration of a program source download system according to the present invention will be described in detail with reference to the accompanying drawings. 1 is a network configuration diagram showing a configuration of a program source download system according to the present invention.

1, the program source downloading system includes a terminal 100, a content portal server 200, and a content download server 300.

The terminal 100 transmits a phone number or UUID (Universal Unique Identifier) information of the terminal to the content portal server 200 when the user accesses the content portal server 200 to purchase a program. Here, UUID is a 128-bit number used to identify an object or entity on the Internet, and is the only information determined for each mobile station as in the case of a telephone number.

Although FIG. 1 illustrates an example in which the terminal 100 is a mobile communication terminal, the terminal 100 is not limited to the hardware type as long as the terminal 100 satisfies the above restrictions.

Meanwhile, the content portal server 200 provides a service for the terminal 100 to access through the wireless network and purchase a program, and transmits the telephone number or UUID information received from the terminal 100 to the content download server 300 ).

The content download server 300 transmits the program source itself to the terminal 100 while encrypting the program source for security. At this time, the program source is encrypted by the XML watermark method using the authentication information (telephone number or UUID) of the terminal 100 as described above.

On the other hand, the program source may be written by C / C ++, java, or other languages, and is a state written in a high-level language before compilation.

2 is a hierarchical view of a terminal 100 applied to the present invention. The terminal 100 includes a download platform 110 for downloading a program source encrypted with XML from the content download server 300, decrypting and compiling the program source and generating a program executable file; And an application layer 120 for executing the program executable file generated by the download platform 110.

2, the download platform 110 includes a source download decryption module 111, a program source compiler 112, a program storage manager 113, and a program execution loader 114.

The source download decryption module 111 compares the encrypted XML source document received from the content download server 300 with its own terminal information, that is, a telephone number or a UUID, and if the encrypted XML source document matches the received XML source document, If it is encrypted using a number or UUID, this time, on the contrary, decrypt it using its own phone number or UUID. Therefore, in the case of an encrypted XML source that does not match the terminal information of the user, it is impossible to decrypt and generate an executable file.

Also, the program source compiler 112 compiles the program source code to generate a binary executable file. In this case, it is needless to say that optimized compilation based on the VM environment or wireless platform specific to the terminal is possible.

Meanwhile, the program storage manager 113 stores a program binary execution file, and the program execution loader 114 searches for and executes a program execution binary file.

Hereinafter, a method of downloading a program source according to an embodiment of the present invention using a system having the above-described configuration will be described with reference to the accompanying drawings.

First, as shown in FIG. 1, a program developer registers a program source with the content download server 300.

Meanwhile, the user of the terminal 100 accesses the content server 200, searches for his / her desired program on the Internet, purchases the program, and performs a processing operation for authentication. Then, the terminal 100 transmits its own phone number or UUID information to the content portal server 200 as shown in FIG. 3 (S110).

When the phone number or UUID information of the terminal 100 is delivered to the content portal server 200, the content portal server 200 transmits the received phone number or UUID information of the terminal 100 to the content download server 200. [ (Step S120).

The content download server 300 firstly transmits the program source to the XML source document 300 using the telephone number or UUID information of the terminal transmitted from the content download server 300 prior to downloading the corresponding program to the terminal 100. [ . This is for the security of the program source, and an important point of the present invention is that the information is uniquely determined for each terminal and is encrypted using an XML source document. Thus, only one terminal 100 can decrypt the encrypted source.

Then, the content download server 300 transmits the encrypted XML source document to the terminal 100 (S130).

Then, the terminal 100 downloads the corresponding XML source document and processes the decrypted XML source document. At this time, if the XML source document downloaded from the content download server 300 is different from its own terminal information, that is, its own telephone number or UUID information, the terminal 100 can not proceed with the decryption, and thus terminates. Further, in order to improve the security, if the XML information does not coincide with the terminal information, the encrypted XML source is deleted.

On the other hand, if the XML source document and its own telephone number or UUID information are the same, the terminal 100 decodes and converts the XML source document into an executable file at step S140.

4 illustrates the detailed procedure of the terminal 100 described above in more detail. That is, the terminal 100 transmits authentication information to the content portal server 200 during a program purchase process (S210). The authentication information at this time may be the telephone number or the UUID information of the terminal itself.

Then, the terminal 100 accesses the content download server 300 and downloads a program source encrypted with XML. The program source is encrypted using the telephone number or UUID information of the terminal 100 (S220 ).

The terminal 100 compares the XML document with the terminal information for decoding the XML source document (S230). If the XML document matches (YES), the terminal 100 decodes the XML document (S240). Therefore, the program source code is generated through the decryption process.

Thereafter, the program execution binary file is finally generated through the compiling process (S250), so that the program execution binary file can be executed in the terminal 100. [

When the program execution binary file is generated through this process, program compilation optimized for an environment such as a VM or a wireless platform of the terminal 100 can be performed, so that the execution speed of the program based on the terminal VM is improved.

On the other hand, if the encrypted XML source document and the terminal information are different (NO) in the comparing step S230, the terminal 100 can not proceed with the decryption process, Thereby enhancing the security (S260).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the scope of the present invention should not be construed as being limited thereby. .
