摘要： Methods, components, and systems for efficient authentication, either through a digital signature or message authentication codes, and verification of a digital stream sent from a source to a receiver via zero or more intermediaries, such that the source or intermediary (or both) can remove certain portions of the data stream without inhibiting the ability of the ultimate receiver to verify the authenticity and integrity of the data received. According to the invention, a source may sign an entire data stream once, but may permit either itself or an intermediary to efficiently remove certain portions of the stream before transmitting the stream to the ultimate recipient, without having to re-sign the entire stream. Applications may include the signing of media streams which often need to be further processed to accommodate the resource requirements of a particular environment. Another application allows an intermediary to choose an advertisement to include in a given slot.

摘要： Under the situation in a network including a transmitter and a receiver in which a transmitter converts a non-compressed packet to be transmitted as a full-header packet including a full header or a header-compressed packet including a compressed header, and sends the converted packet to the receiver, the transmitter sends at least an important packet in the non-compressed packet to be transmitted as a full-header packet. The important packet means for example, a packet containing the data serving an important role when the data terminal eventually receiving each packet reproduces the audio and/or image in accordance with the data in each packet.
摘要翻译：在包括发射机和接收机的网络的情况下，发射机将要发送的非压缩分组转换为包括包含压缩报头的完整报头或报头压缩分组的全标头分组，并将转换后的分组发送到接收机，发送器至少发送非压缩分组中的重要分组作为全标头分组发送。重要的分组意味着例如，当数据终端最终接收每个分组时，包含数据服务重要角色的分组根据每个分组中的数据再现该音频和/或图像。

摘要： A delay unit 103 adds holding time that has been set by a holding time setting unit 104 to a received data. The holding time is computed based on delay time of received data and the minimum delay time of data received up to a certain point for the purpose of reducing a total delay time. The delay time is estimated in a delay time estimating unit 106 from the difference between a reception time of a packet counted based on an internal clock generator 107 and a time designated by a time stamp in the received packet.

摘要： Cryptographically Protected Prefixes (“CPPs”) are used to create IP addresses, preventing any correlation between a CPP IP address and a host's geographic location. An IP address is subdivided into address prefixes of multiple segments. Each segment is encrypted with a cryptographic key known only to a subset of routers in the access network domain (or Privacy Domain). Therefore, each router obtains the information it needs to forward a packet of information, but not any additional information.
摘要翻译：密码保护前缀（“CPP”）用于创建IP地址，防止CPP IP地址与主机的地理位置之间的任何相关性。 IP地址被细分为多个段的地址前缀。每个段都使用仅在接入网络域（或隐私域）中的路由器的一部分已知的加密密钥进行加密。因此，每个路由器获得转发一个信息包所需的信息，但没有任何附加信息。

摘要： The frame-forming data computing part 101 sorts a plurality of types of parameters forming the frames, and generates frame-forming data that contains data relating to the configuration of said frames and data establishing for each class the error protection method to be applied to each said parameter. The frame-forming data error protection processing part 102 implements the specified error protection for said frame-forming data. The class data error protection processing part 103 implements error protection that is specified for each class according to the frame-forming data, with respect to the parameters that are sorted into a plurality of classes. The synthesizer 104 transmits the frame-forming data that has undergone the specified error protection and the parameters that have undergone the error protection established for each class. In accordance with the present invention, error correction is implemented on frame-forming data indicating the configuration of the frames, and it is also implemented on each class according to the frame-forming data, and these two are synthesized and output. Therefore, it becomes possible to obtain data relating to the configuration of said frames, according to frame-forming data received by the receiving side device. As a result, it is possible to set on the transmission side as desired the content of the error protection to be applied to each class, and in addition, error protection becomes possible for each frame, due to the fact that these data are contained in the frame-forming data, even if the frame has a variable frame length, with the number of bits fluctuating over time.

摘要： A sender converts a non-compressed packet, which is to be transmitted, into a full-header packet including a full header or a header-compressed packet including a compressed header, and sends the converted packet to a receiver. The receiver receives the packet transmitted from the sender, and converts the received packet into a decompressed packet. In cases the full-header packet or header-compressed packet is lost between the sender and receiver, the receiver keeps header-compressed packers received during an interval from the packet loss to the next earliest reception of a full-header packet, and decompresses the compressed headers of the kept header-compressed packets on the basis of contents of the full header of the full-header packet.

摘要： A network system includes a network edge point configured to provide a terminal with access to a network. The network edge point includes a security policy associated with the terminal, and controls communications between the network and the terminal according to the security policy. The security policy may include a personal filter downloaded from the terminal, a service filter downloaded from a service policy server, and/or a domain filter downloaded from a domain policy server. The terminal may access the network through a second network edge point. The second network edge point may download one or more of the filters from the first network edge point, and control communications between the network and the terminal according to the security policy.

摘要： The writing address supply part 210 supplies writing addresses for writing the bits forming bit sequences corresponding to the header H contained in a frame to be transmitted or stored and bit sequences corresponding to the data D, into the operating memory 220. The reading address supply part 230 alternately supplies to the operating memory 220 a plurality of addresses for reading a plurality of continuous bits corresponding to the header H from the operating memory 220, and an address for reading 1 bit corresponding to the data D from the operating memory 220, and reads the bit sequence such that the bits forming the bit sequence corresponding to the header H are scattered and arranged within the bit sequence forming the data D, from the operating memory. In accordance with such an interleaving device, it is possible to individually randomize frames according to their constituent data, and it is possible to transmit the bits that make up such data in a format which is most suited for said data.
