A package file extracting unit 800 for extracting the decrypted package as original data and a package file loading unit 900 for processing the extracted files to be normally loaded in the training common platform environment can be included.

A brief description of the flow of the package creation system of the present invention will be given first. In the package creation tool unit 100, a content created by a copyright owner or a developer is encrypted Processing is performed in the encryption unit 200, the cryptographic key unit 300, and the certificate name unit 400.

When the package creation is completed, the package transfer is performed to the marketplace of the package transferring unit 500. When the purchaser purchases contents intending to purchase in the marketplace, the purchase signing unit 600 processes the signature through the information of the purchaser, The decryption unit 700 processes decryption for the encrypted package.

The package file extracting unit 800 extracts the decrypted package as original data and can use the content in the training common platform environment when loading is performed in the package file loading unit.

Hereinafter, each configuration of the package creation system of the present invention will be described.

The package creation tool unit 100 creates a package for a content file by using a package creation tool for content created by a copyright holder or a developer.

The encryption unit 200 may include a content data file and a file having important information about the file. The technique used at this time may encrypt data through an XML document parsing module using, for example, an XML encryption technique.

The cryptographic key unit 300 is responsible for the generation of a cryptographic key required to perform encryption for the content developed by the copyright holder or the developer. The encryption key can be largely composed of a public key and a private key, generates an authentication key with the private key and the public key of the copyright holder, and generates the encryption key using the generated key value.

The certificate list 400 performs signing of the copyright holder with respect to the package through the RSA encryption algorithm used for the digital signature, and the package includes the final security element and is converted into a package form that can be registered in the marketplace .

The package transmission unit 500 configures the packet data including the final security element into a packet structure in which a header field command field, a checksum field, and an error field are added, and transmits the packet data to the marketplace by mutual communication and protocol.

The package purchase signature unit 600 performs signature of the buyer with respect to the package when the buyer purchases the content through a legitimate transaction in the marketplace. The file format registered in the marketplace is an encrypted package. When the purchaser selects the content to be used by the marketplace and completes the payment, the RSA signature information of the copyright holder is deleted and the buyer's RSA signature information is inserted. Like the authentication signature unit 400, the signature encryption algorithm can perform purchase signing for the purchased package using the RSA encryption algorithm.

The package decryption unit 700 is configured to restore the encrypted package to the original content file. The package decryption unit 700 may be configured with encrypted XML, key encryption related information, data, resource, and password file of the package. The authentication is performed using the buyer's private key and public key, and the encrypted package can perform decryption using the buyer's encryption key. That is, when the authentication is completed with a pair of the symmetric key and the private key of the purchaser, the package encrypted with the XML encryption module is decrypted through the XML decryption parsing module of the training common platform environment.

The package file extracting unit 800 extracts the original data and the content file structure after performing the decoding process of the package and performs data decoding and decoding in the XML decoding parsing module provided in the common platform based on the training It is possible to extract the files having the original contents data. The package can be extracted from the buyer's PC or mobile and generated and stored as project type data.

The package file loading unit 900 may register the project as a project on the training common platform by loading the content files through the step of matching and authenticating the license information and the content information at the time of installing the platform on the buyer's PC.

FIG. 2 is a flowchart illustrating a process of generating a package through a package creation tool unit. Referring to FIG. 2, the package creation tool unit performs a program packaging (S110) as a first process for a user to perform distribution.

Finally, the packed Asset may be encrypted through the XML document parsing module (S210), and the encrypted data may be generated by encrypting the packaged Asset data (220).

Next, a step S230 of generating a private key and a public key in the key generation module is performed, and a step S240 of generating a key authentication value by generating a password authentication key value is performed. A cryptographic key for encrypting the entire data may be formed by performing a step S250 of adding a copyright holder signature to the encrypted key.

In operation S280, the encryption module encrypts the encrypted data and the encrypted data to form an encrypted file by formatting the encrypted data in operation S260, and transmits the encrypted file to the packaging module in operation S280.

That is, the embodiment generates an authentication key value using the private key and the public key through the key generation module, and generates data signatures and XML-based encrypted files through the generated authentication key value. A plurality of ciphers and files generated as described above are created through a packaging module in one compressed form of distribution file.

Figure 4 is a flow diagram illustrating a method for extracting an encrypted package from a marketplace. Referring to FIG. 4, as a decryption process for extracting a package, files and data are extracted by the unpackaging module (S710), and the decrypted downloaded package is decrypted through an XML document parsing module (S720). If a legitimate transaction is made, an authentication key is allocated, and decoding 730 is performed. At this time, the public key and the private key of the purchaser are required, and the public key and the private key are decrypted through the key decryption module for generating the key pair to decrypt the package (S740).

At this time, in order to insert the unique information of the buyer, a process of processing the signature of the buyer to the XML file (S760) is performed. At this time, the buyer decodes the encrypted file with the encryption key and extracts the decrypted file and data have. The decrypted files and data may be transferred to the package file extracting unit 800 and extracted into a structure of a content project type in the buyer's PC and mobile environment.

Referring to FIG. 6, the marketplace server receives a packet for an approved package (S540). In order to check whether the packet is validated by the marketplace server, a packet check is performed through the module and a cipher text encapsulating the packet is decoded (S550). The data size and the capacity of the decoded data packet are checked to determine whether it is a normal data structure (S560).

If the error detection is not performed while having a normal data structure, a process of recognizing the product as a normal content product and registering and selling the product in the marketplace may be performed (S590). If it is determined that the data is not normal data, the marketplace server sends a message to the copyright holder to retransmit, and the copyright holder performs error checking on the package and performs retransmission to the marketplace (S570). When the package is retransmitted from the marketplace, it can be normally sold as a product to the marketplace through error checking and checking (S580).

FIG. 7 is a flowchart showing a process of passing through the package creation system of the present embodiment to the copyright holder.

Referring to FIG. 7, an action content package is created using a packaging tool for a target package, which is called a content authoring tool. At this time, the package may be composed of an XML encryption file, an encryption key, and an encrypted data file. Through the packaging as described above, it is possible to prevent the forgery and alteration of the content, protect the copyright of the copyright holder, and activate the training content in the marketplace.
