摘要： A method for coded data transmission from a sender to at least one receiver, wherein the transmission data is divided into single source packets p i , the method comprising the steps of generating encoded packets from said source packets p i by applying rateless erasure codes, transmitting said encoded packets to said at least one receiver, and decoding said encoded packets in order to obtain said source packets p i by applying a decoding process with on-the-fly decodability functionality, wherein already decoded source packets p i are employed by the decoding process for decoding remaining encoded packets, the method being characterized in that an integrity check is performed on source packets p i obtained in the decoding process before accepting said source packets p i for being employed by the decoding process for further decoding. Furthermore, an apparatus for decoding coded data is disclosed.
摘要翻译：一种用于从发送器到至少一个接收器的编码数据传输的方法，其中所述传输数据被划分为单个源分组pi，所述方法包括以下步骤：通过应用无可读擦除代码从所述源分组pi生成编码分组，分组到所述至少一个接收机，并且解码所述编码分组，以便通过应用具有即时可解码功能的解码处理来获得所述源分组pi，其中已经解码的源分组pi被解码过程用于解码剩余所述方法的特征在于，在接受所述源分组pi之前，在解码过程中获得的源分组pi执行完整性检查，以被解码处理用于进一步解码。此外，公开了一种用于解码编码数据的装置。

摘要： For allowing a very effective and privacy friendly identification of potentially malicious network elements within a network a method for identifying potentially malicious network elements within a network, wherein the network comprises multiple domains administrated by different operators, is claimed. The method is characterized in that at least some of said operators transmit qualifying information regarding at least one network element, said at least one network element being qualified as being potentially malicious, to a functional entity, and wherein the functional entity provides an alarm information and/or alarm activity, if a predefined number of operators has transmitted such qualifying information regarding the same potentially malicious network element to the functional entity. Further, an according network is claimed, preferably for carrying out the above mentioned method.
