  • Patent number: 7359339
    Abstract: The present invention provides a “smart” AP, whereby the AP periodically checks its connection with a network and, if a determination is made that the connection between the AP and the network server has been lost, an indication of this loss of connection is made available to all wireless stations connected to the AP. In a preferred embodiment, the indication given to the wireless stations is in the form of an SSID change. When the AP detects the loss of network connection, it automatically changes its SSID from a primary SSID to an alternative SSID. The wireless stations receive the alternative SSID and, since they are configured to connect to the primary SSID, immediately and automatically begin to search for another AP in the system that is using the primary SSID, and then connect to AP having the strongest signal. In one embodiment, the alternative SSID's can be selected so as to provide diagnostic assistance to a person attempting repairs to the faulty AP/network connection.

  • Patent number: 7353428
    Abstract: A client computer is connected via a network to an anti-virus server and polls the server for indication that an anti-virus needs to be immediately downloaded from the anti-virus server. The client computer disengages from the network, and re-establishes a link with only the trusted anti-virus server. The anti-virus fix is installed, the client computer re-booted, and the client computer is then allowed to reconnect to the full network. If the client's primary operating system (OS) is infected, a secondary OS in the client computer performs the anti-virus download and execution. The disengagement from the network is performed by applying a filter in a network interface card (NIC) driver by the primary OS, the secondary OS, a service processor (SP), or by a virtual machine manager (VMM), depending on which is available at the client computer.

  • Patent number: 7343493
    Abstract: A method for restricting access to an encryption key of an encrypted file system (EFS), whereby access is provided only when a computer system is booted in a trusted state. The EFS encrypts the files within a TPM chip according to TCPA specifications and simultaneously creates the encryption key, which is also stored in the TPM. The key is sealed to one or more platform control register (PCR) states (i.e., the TPM will export the key only when the PCRs are in a pre-defined state.). The original PCR states are modified during boot up of the computer system via a secure hashing algorithm, which extends a value of one PCR to a next PCR at each stage of the boot process and then hashes the value with the remaining content of the next PCR. When the system boot process is completed and before control passes to the user, the values within the PCRs are compared to values stored in a PCR table within the TPM, and the encryption key is exported to the OS kernel only when the PCR values match the table values.
