摘要: A method, apparatus and system for transmitting control information in a header of a physical protocol data unit (PPDU), such as an IEEE 802.11 compliant PPDU. Embodiments include indicating control features in an EDMG PPDU for Wireless LAN communications. The method and system may include overloading at least one bit of a Scrambler Initialization Field in the PPDU header (e.g. the PHY header) to convey control information, as well as to be used to initialise the scrambler shift register. The same header bits are thus used for both purposes. Examples of control information include a primary channel, channel width or MIMO configuration to be used in further communication.

摘要: 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.

摘要: 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.
