20080313462 | APPARATUS AND METHOD FOR DERIVING KEYS FOR SECURING PEER LINKS - Apparatus and methods to establish a secure peer-to-peer link in which the construction of a link authentication and key encryption keys are separated from the session encryption key are described herein. In an embodiment, a secure peer-to-peer link is established in a wireless mesh network. | 12-18-2008 |
20080313698 | APPARATUS AND METHODS FOR NEGOTIATING A CAPABILITY IN ESTABLISHING A PEER-TO-PEER COMMUNICATION LINK - Apparatus and method to negotiate parameters of a policy in establishment of a peer-to-peer link are described herein. In an embodiment, a security policy is negotiated in establishment of a peer-to-peer link in a wireless mesh network. | 12-18-2008 |
20090327694 | Methods and apparatus for providing integrity protection for management and control traffic of wireless communication networks - Embodiments of the present invention provide a method comprising transmitting, by a communication node, an information element (IE), the IE including a feature field indicating whether the communication node operates in accordance with an integrity protection protocol specifically for management frames, and the IE further including an enforcement field that advertises whether the integrity protection protocol for management and control frames is mandatory, and generating, by the communication node, a pairwise transient key (PTK), the PTK including a first plurality of keys and a pairwise integrity key (PIK), wherein the first plurality of keys are configured to protect an integrity of data frames transmitted by the communication node and the PIK is configured to protect an integrity of management frames transmitted by the communication node, wherein management frames are dedicated to management traffic and wherein the first plurality of keys and the PIK are different keys. Other embodiments may be described and claimed. | 12-31-2009 |
20110150223 | WIRELESS DEVICE AND METHOD FOR REKEYING WITH REDUCED PACKET LOSS FOR HIGH-THROUGHPUT WIRELESS COMMUNICATIONS - Embodiments of a wireless device and methods for rekeying with reduced packet loss in a wireless network are generally described herein. In some embodiments, during rekeying operations a new key for reception may be installed early (i.e., prior to receipt of a rekeying confirmation message). The use of the new key for transmission may be delayed until after receipt of the rekeying confirmation message. The early installation of the new key for reception may allow both the new key and old key to be active at the same time for use decrypting received packets to reduce packet loss during rekeying operations. The rekeying confirmation message may be the fourth message of a four-way handshake for rekeying. In some embodiments, two key identifiers may be alternated between four-way handshakes to prevent deletion of the old key. | 06-23-2011 |
20120084411 | METHOD, APPARATUS AND SYSTEM FOR MAINTAINING MOBILITY RESISTANT IP TUNNELS USING A MOBILE ROUTER - A method, apparatus and system enable a mobile device to roam while maintaining a persistent IP tunnel. Specifically, a mobile router may be utilized to enable a mobile device to maintain a persistent IP tunnel while the device roams. In one embodiment, the mobile device is a virtual host and the mobile router is a virtual mobile router. | 04-05-2012 |
20120102212 | METHOD, APPARATUS AND SYSTEM FOR PLATFORM IDENTITY BINDING IN A NETWORK NODE - Embodiments of apparatuses, articles, methods, and systems for binding various platform identities for a policy negotiation are generally described herein. Other embodiments may be described and claimed. | 04-26-2012 |
20120185696 | DEVICE INTRODUCTION AND ACCESS CONTROL FRAMEWORK - In an embodiment, a method includes registering applications and network services for notification of an out-of-band introduction, and using the out-of-band introduction to bootstrap secure in-band provisioning of credentials and policies that are used to control subsequent access and resource sharing on an in-band channel. In another embodiment, an apparatus implements the method. | 07-19-2012 |
