Abstract: Systems and methods mark or identify network data as being of interest by modifying the network data with a tag. A tag may be an unordered set of tag elements, and each tag element may be an ordered sequence of bits. For each data segment or packet transmitted, one or more fields of a network packet may be masked with a randomly chosen tag element.

Abstract: A semiconductor die includes a substrate, a first passivation layer over the substrate, and a second passivation layer over the first passivation layer and the substrate. The substrate has boundaries defined by a substrate termination edge. The first passivation layer is over the substrate such that it terminates at a first passivation termination edge that is inset from the substrate termination edge by a first distance. The second passivation layer is over the first passivation layer and the substrate such that it terminates at a second passivation termination edge that is inset from the substrate termination edge by a second distance. The second distance is less than the first distance such that the second passivation layer overlaps the first passivation layer.

Abstract: A system and method detects or prevents tampering of computer networks by transmitting address messages indicating that unused network addresses are in use. The systems and method handles requests for network resources, such as Address Resolution Protocol (ARP) messages, and provides fabricated information to a potential attacker to disrupt an attack on an information system.

Abstract: A method of fabricating an integrated circuit on a silicon carbide substrate is disclosed that eliminates wire bonding. The method includes fabricating a semiconductor device in epitaxial layers on a surface of a silicon carbide substrate and with at least one metal contact for the device on the uppermost surface of the epitaxial layer. The opposite surface of the substrate is then ground and polished until it is substantially transparent. The polished surface of the silicon carbide substrate is then masked to define a predetermined location for at least one via that is opposite the device metal contact and etching the desired via in steps. The first etching step etches through the silicon carbide substrate at the desired masked location until the etch reaches the epitaxial layer. The second etching step etches through the epitaxial layer to the device contacts. Finally, the via is metallized.
