  • Publication number: 20080065888
    Abstract: A system and method of security authentication and key management scheme in a multi-hop wireless network is provided herein with a hop-by-hop security model. The scheme adapts the 802.11r key hierarchy into the meshed AP network. In this approach, a top key holder (R0KH) derives and holds the top Pairwise Master Key (PMK_0) for each supplicant wireless device after the authentication process. All authenticator AP take the level one key holder (R1KH) role and receive the next level Pairwise Master Key (PMK_1) from R0KH. The link level data protection key is derived from PMK_1 via the 802.11i 4-way handshaking.

  • Publication number: 20050138480
    Abstract: A method and apparatus for executing a selective recovery after a branch misprediction is disclosed. In one embodiment, the instructions following the mispredicted branch point may be saved for selective re-execution in a buffer. Those instructions that wrote to physical registers between the mispredicted branch point and an exact convergence point, thereby causing false data dependencies, may be followed by corresponding move instructions to eliminate the false data dependencies. The instructions subsequent to the exact convergence point may then be selectively re-executed if subject to the previous false data dependencies.
