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 present invention provides a method and system for handoff in a wireless communication network. In one embodiment, a common handoff encryption key is generated by an authentication server and transmitted to a first access point and a second access point. The first access point transmits the handoff encryption key to a wireless terminal. The wireless terminal encrypts output data with the handoff encryption key. When the wireless terminal is associated with the second access point, the second access point decrypts data from the wireless terminal with the handoff encryption key. In a second embodiment, a handoff WEP key generation secret parameter is provided to a first and a second access point. Both access points generate a handoff WEP key as a function of the handoff WEP key generation secret parameter and an address of a wireless terminal. The first access point transmits the handoff WEP key to the wireless terminal. The second access point communicates data packets encrypted with the handoff WEP key with the wireless terminal.
摘要翻译：本发明提供了一种用于无线通信网络中切换的方法和系统。在一个实施例中，公共切换加密密钥由认证服务器生成并被发送到第一接入点和第二接入点。第一接入点将切换加密密钥发送到无线终端。无线终端用切换加密密钥加密输出数据。当无线终端与第二接入点相关联时，第二接入点利用切换加密密钥从无线终端解密数据。在第二实施例中，将切换WEP密钥生成秘密参数提供给第一和第二接入点。两个接入点根据切换WEP密钥生成秘密参数和无线终端的地址生成切换WEP密钥。第一接入点将切换WEP密钥发送到无线终端。第二接入点将与切换WEP密钥一起加密的数据分组与无线终端进行通信。

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.
