  • Patent number: 7793094
    Abstract: An intrusion detection system and method for a computer network includes a processor and one or more programs that run on the processor for application inspection of data packets traversing the computer network. The one or more programs also obtaining attribute information from the packets specific to a particular application and comparing the attribute information against a knowledge database that provides a baseline of normal network behavior. The processor raises an alarm whenever the attribute information exceeds a predetermined range of deviation from the baseline of normal network behavior.

  • Publication number: 20070245137
    Abstract: A security device for a network operates to inspect data packet traffic outgoing from an application server, the data packet traffic including a data packet destined for a client device, the data packet containing a cookie created by the application server. The security device is further operable to extract the cookie from the data packet, encrypt the cookie using a secure key, and then send the encrypted cookie to the client device for storage thereon. It is emphasized that this abstract is provided to comply with the rules requiring an abstract that will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

  • Patent number: 7277808
    Abstract: Electrical fuses (eFuses) are applied to the task of achieving very tightly controlled Input-Output (I/O) timing specifications. The I/O timing is made programmable and subject to adjustment as part of wafer probe testing. The techniques of parametric adjustment presented are based upon what is commonly referred to as clock skewing or clock tuning. The invention describes methods to select the clock skewing on a die-to-die basis based on functional testing with the actual parametric limits imposed on parameters of interest. The results associated with each die form the basis for hard-programming the selected clock skew value into the die via electrical fuses.

  • Patent number: 7095671
    Abstract: Electrical fuses (eFuses) are applied to the task of memory performance adjustment to improve upon earlier fuse techniques by not requiring an additional processing step and expensive equipment. Standard electrical fuse (eFuse) hardware chains provide a soft test feature wherein the effect of memory slow-down can be tested prior to actually programming the fuses. Electrical fuses thus provide a very efficient non-volatile method to match the logic-memory interface through memory trimming, drastically cutting costs and cycle times involved.
