    • The present invention provides methods and devices for a security architecture for use in wireless multi-hop networks. A method for implementing pair-wise encryption key establishment, network node authentication and determining tunnel encryption keys is provided in a following manner. In a multi-hop wireless network including a plurality of network nodes, pair-wise security is established between pairs of neighboring network nodes of the plurality of network nodes. For example, pair-wise security is established in the form of temporal pair-wise encryption keys. Following establishment of pair-wise security between pairs of neighboring network nodes, for a pair of network nodes that are not neighbors, tunnel security is established between the pair of network nodes using tunnel encryption keys derived by the pair of network nodes on an ad hoc basis. The tunnel encryption keys are used to form the connection between non-neighboring network nodes so as to avoid the hop-by-hop encryption/decryption used in conventional multi-hop wireless systems.
    • 本发明提供了用于无线多跳网络中的安全架构的方法和装置。 以下列方式提供用于实现成对加密密钥建立,网络节点认证和确定隧道加密密钥的方法。 在包括多个网络节点的多跳无线网络中,在多个网络节点的相邻网络节点对之间建立成对的安全性。 例如,以时间成对加密密钥的形式建立成对安全性。 在建立成对的相邻网络节点之间的成对安全性的情况下,对于不是邻居的一对网络节点,在一对网络节点之间使用由一对网络节点导出的隧道加密密钥来建立隧道安全性 基础。 隧道加密密钥用于形成非相邻网络节点之间的连接,以避免在传统的多跳无线系统中使用的逐跳加密/解密。

    • A security zone key is used to secure data traffic/control messages in a multi-hop wireless relay network. In one embodiment, the security zone key is generated by a base station and passed to relay stations and optionally mobile stations that are to be associated with the security zone. A given base station may implement multiple security zones on the wireless network. The members in each zone share a unique group security association. One or more connections may be assigned to a particular security zone. Data traffic/control messages directed to relay stations in a security zone are processed using the security zone key to enable all relay nodes within the security zone to verify the authenticity of the management message and optionally decode the messages. From a management perspective, since a common security zone key is in use by all relay stations in the security zone, the management messages may be broadcast/multicast to the relay nodes in the security zone and the key distribution and management protocols have much less complexity.
    • 安全区域密钥用于在多跳无线中继网络中保护数据流量/控制消息。 在一个实施例中,安全区密钥由基站生成,并被传递给将要与安全区相关联的中继站和可选的移动站。 给定的基站可以在无线网络上实现多个安全区域。 每个区域中的成员共享独特的组安全关联。 可以将一个或多个连接分配给特定的安全区域。 使用安全区域密钥来处理指向安全区域中的中继站的数据业务/控制消息,以使得安全区域内的所有中继节点能够验证管理消息的真实性并且可选地对消息进行解码。 从管理的角度来看,由于安全区域中的所有中继站正在使用公共安全区域密钥,所以管理消息可以被广播/组播到安全区域中的中继节点,并且密钥分配和管理协议的复杂度要少得多 。
