    • According to a first aspect of the present invention there is provided a method of implementing a virtual scratch-card game. The method comprises, at a virtual scratch-card sever 6, selecting a plurality of symbol identifiers that are associated with respective symbols, individually encrypting each of the selected symbol identifiers, and sending the encrypted symbol identifiers to a virtual scratch-card client 7. At the virtual scratch-card client 7, displaying a representation of a virtual scratch-card to a user and, in response to selection of an encrypted symbol identifier by the user, identifying the selected encrypted symbol identifier to the virtual scratch-card server 6. At the virtual scratch-card serve 6r, determining verification information associated with the selected encrypted symbol identifier, and sending the verification information to the virtual scratch-card client 7. At the virtual scratch-card client 7, using the verification information to verify that the selected encrypted symbol identifier results from the encryption of the corresponding symbol identifier initially selected by the virtual scratch-card server 6.
    • 根据本发明的第一方面,提供了一种实现虚拟刮板游戏的方法。 该方法包括在虚拟刮刮卡服务器6处,选择与相应符号相关联的多个符号标识符,单独地加密所选择的符号标识符中的每一个,并将加密的符号标识符发送到虚拟刮刮卡客户端7。 在虚拟刮刮卡客户机7处,向用户显示虚拟刮刮卡的表示,并且响应于用户选择加密的符号标识符,将所选择的加密符号标识符识别到虚拟刮卡服务器6 在虚拟刮卡服务器6r上,确定与所选择的加密符号标识符相关联的验证信息,并将验证信息发送到虚拟刮刮卡客户端7.在虚拟刮刮卡客户端7处,使用验证信息来验证 所选择的加密符号标识符是由最初由virt选择的相应符号标识符的加密产生的 ual刮卡服务器6。

    • A method of setting up a secure IPTV session. An Application Server (AS) receives an invite message from an IPTV receiving node such as a mobile telephone or a Set Top Box (STB) to set up an IPTV session. The invite message includes a Bootstrapping Transaction Identifier (BTID) associated with the receiving node. The AS sends an authentication request to a Service Access Protection Server, the authentication request including the BTID. The AS then receives from the Service Access Protection Server an authentication response, which includes a long term key associated with the IPTV receiving node, the long term key having been previously provided to the IPTV receiving node. A request is sent to an IPTV content provider node, the request identifying the IPTV receiving node. The AS then encrypts a media encryption key that is used to encrypt the media sent by the IPTV content provider, using the received long term key. An invite response is then sent to the IPTV receiving node, the response including the encrypted media encryption key.
    • 一种建立安全IPTV会话的方法。 应用服务器(AS)从诸如移动电话或机顶盒(STB)的IPTV接收节点接收邀请消息以建立IPTV会话。 邀请消息包括与接收节点相关联的引导事务标识符(BTID)。 AS向服务访问保护服务器发送认证请求,认证请求包括BTID。 AS然后从服务访问保护服务器接收包括与IPTV接收节点相关联的长期密钥的认证响应,该长期密钥先前已经提供给IPTV接收节点。 向IPTV内容提供商节点发送请求,该请求标识IPTV接收节点。 AS然后使用接收到的长期密钥加密用于加密由IPTV内容提供商发送的媒体的媒体加密密钥。 然后,向IPTV接收节点发送邀请响应,响应包括加密的媒体加密密钥。

    • A method and apparatus for providing a packet switched television guide such as an Electronic Programme Guide or an Electronic Service Guide to a user. An Application Server receives and stores preferences relating to a packet switched television guide. When the Application Server subsequently receives a new or updated packet switched television guide from a packet switched television Guide Application Server, the Application Server filters elements of the packet switched television guide according to the preferences to remove information not relevant to a user associated with the preferences. The filtered packet switched television guide is then sent to the user. In this way, only relevant information is sent, which can reduce the bandwidth required in sending packet switched television guides, the frequency at which packet switched television guide updates need to be sent, and also the processing required by the user's receiving equipment in filtering out irrelevant information from the packet switched television guide.
    • 一种用于向用户提供诸如电子节目指南或电子服务指南的分组交换电视指南的方法和装置。 应用服务器接收并存储与分组交换电视指南相关的偏好。 当应用服务器随后从分组交换电视指南应用服务器接收到新的或更新的分组交换电视指南时,应用服务器根据偏好过滤分组交换电视指南的元素以去除与偏好相关联的用户不相关的信息 。 然后将经过滤的分组交换电视指南发送给用户。 以这种方式,仅发送相关信息,这可以减少发送分组交换电视指南所需的带宽,需要发送分组交换电视指南更新的频率,以及用户接收设备过滤所需的处理 来自分组交换电视指南的不相关信息。
