    • Provided is a path-token-based web service caching method including determining whether or not stored cache data exists when a web service call request exists, and when the cache data does not exist, creating a predetermined path-token set and a predetermined tag data set based on a message schema of Web Services Description Language (WSDL), and creating a request Simple Object Access Protocol (SOAP) message, creating a request SOAP message template by using a path-token for the created request SOAP message, and calling the web service, and creating cache data including the tag data set, input values set, the request SOAP message template, the request SOAP message, and SOAP binding information. Accordingly, the method can solve the problems of a conventional web service caching method whereby the method can not cope with change in the number of inputs, and an exact input position is not searched for when an input value is changed. Therefore, it is possible to implement an efficient web service call environment by web service caching.
    • 提供了一种基于路径令牌的Web服务高速缓存方法,包括当存在web服务呼叫请求时确定是否存在存储的高速缓存数据,并且当高速缓存数据不存在时,创建预定路径令牌集和预定标签数据 基于Web服务描述语言(WSDL)的消息模式进行设置,并创建请求简单对象访问协议(SOAP)消息,通过使用创建的请求SOAP消息的路径令牌来创建请求SOAP消息模板,并调用 Web服务,以及创建包括标签数据集,输入值集,请求SOAP消息模板,请求SOAP消息和SOAP绑定信息的缓存数据。 因此,该方法可以解决传统的web服务缓存方法的问题,由此该方法不能应付输入数量的变化,并且当输入值改变时,不搜索精确的输入位置。 因此,可以通过Web服务缓存来实现高效的Web服务呼叫环境。

    • Provided are a conditional access system and a method of using a conditional access image. The conditional access system according to an exemplary embodiment of the present invention includes: a service key management client allocated with a service key from a service key management server using a service key distribution protocol; a download client downloading a conditional access image using the service key and requesting updating the service key to the service key management server through the service key management client when the downloading is completed; and an execution controller encrypting and storing the conditional access image using the service key updated in accordance with the request and recovering the conditional access image using the service key reacquired through the service key management client before executing the stored conditional access image.
    • 提供条件访问系统和使用条件访问映像的方法。 根据本发明的示例性实施例的条件访问系统包括:使用服务密钥分发协议从服务密钥管理服务器分配服务密钥的服务密钥管理客户机; 下载客户端,当下载完成时,使用服务密钥下载条件访问映像,并通过服务密钥管理客户端向服务密钥管理服务器请求更新服务密钥; 以及执行控制器,使用根据所述请求更新的服务密钥来加密和存储所述条件访问映像,并且在执行所存储的条件访问映像之前,使用通过所述服务密钥管理客户端重新提供的服务密钥来恢复所述条件访问映像。

    • Disclosed herein is a software-based conditional access image download client device. The software-based conditional access image download client device includes a download management module, a conditional access image splitter, and a conditional access image restoration unit. The download management module establishes a secure channel for communicating with a download server device over a network, and communicates with the download server device in compliance with a download protocol. The conditional access image splitter splits a conditional access image, received via the download management module, into a plurality of files, generates a plurality of encrypted files by encrypting the plurality of files, and stores the plurality of encrypted files. The conditional access image restoration unit restores the plurality of encrypted files to the conditional access image when the conditional access image is required.
    • 这里公开了一种基于软件的条件访问图像下载客户端设备。 基于软件的条件访问图像下载客户端设备包括下载管理模块,条件访问映像分离器和条件访问映像恢复单元。 下载管理模块建立用于通过网络与下载服务器设备进行通信的安全通道,并且根据下载协议与下载服务器设备进行通信。 条件访问映像分离器将经由下载管理模块接收的条件访问映像分割成多个文件,通过加密多个文件来生成多个加密文件,并存储多个加密文件。 当需要条件访问图像时,条件访问图像恢复单元将多个加密文件恢复到条件访问图像。
