Methods and apparatuses for providing DRM interoperability are provided. Proxy re-encryption technique using bilinear map is used, and the same content can be used in different devices. According to the method of providing DRM interoperability includes in proxy agent with respect to digital rights management (DRM) service providers and device which supports predetermined DRM, first DRM service provider, second DRM service provider, the proxy agent, and the device identify each other, and proxy re-encrypt an interoperable content (IC) and provide the IC to the device. The IC is second-level encrypted by using a key of the first DRM service provider, and the proxy re-encryption is performed by using a proxy key generated from proxy key information provided from the first DRM service provider and the second DRM service provider. Therefore, a problem in which interoperability cannot be guaranteed since a DRM technique depends on a service provider is resolved.

A semiconductor device includes a wafer and a dicing saw tape that is laminated to a back surface of the wafer. An active surface of the wafer is opposite the back surface of the wafer. The semiconductor device further includes a lamination tape disposed in contact with the wafer. The lamination tape includes an under-film layer contacting the active surface of the wafer. The lamination tape further includes an adhesive layer contacting the under-film layer.

A semiconductor device begins with a wafer having a plurality of bumps formed on a surface of the wafer. An under-film layer is formed over the wafer to completely cover all portions of the bumps with the under-film layer. An adhesive layer is formed over the under-film layer. A support layer is attached over the adhesive layer. A back surface of the wafer undergoes grinding. The support layer provides structural support to the wafer. The support layer is removed to expose the adhesive layer. The adhesive layer is removed to expose the under-film layer. The wafer is singulated into semiconductor die. The semiconductor die is mounted to a substrate by applying force to a back surface of the semiconductor die to press the bumps through under-film layer to contact the substrate while the under-film layer provides an underfill between the semiconductor die and substrate.

An apparatus and method for providing traceback connection using a connection redirection technique are provided. A packet blocking unit blocks an attack packet transmitted to the system and a first response packet output from the system in response to the attack packet, if a system attack sensing signal is received. A response packet generation unit generates a second response packet into which a watermark is inserted, in response to the attack packet, and transmits the second response packet to a system corresponding to the source address of the attack packet. A path traceback unit receives a detection packet containing transmission path information of the second response packet from a system existing on a transmission path of the second response packet, and based on the received detection packet, traces back the transmission path of the second response packet and identifies the location of the attacker system. According to the apparatus and method, even when an attacker attacks a predetermined system via a plurality of systems, the actual location of the attacker system can be traced back fast and accurately and damage of the victim system can be minimized.

Embodiments herein disclose a method for controlling a non-linear effect of a power amplifier by an apparatus. The method includes acquiring an input data of the power amplifier of the apparatus and an output data of the power amplifier. Further, the method includes determining an inverse function using a neural network. The inverse function maps normalized output data of the PA to the input data of the PA, where the neural network comprises at least one sub-network for at least one memory tap from a plurality of memory taps in the neural network. Further, the method includes modifying the input data based on the determined inverse function value by dynamically changing a usage of the at least one memory tap from the plurality of memory taps. Further, the method includes compensating the non-linear effect in the output data of the power amplifier.

A modular paneled structure, comprising a main panel with a symmetric profile which has a closed-sectional portion in the middle and open-sectional portions at each end; and further comprising a cover panel which interconnects two side-by-side main panels, where the cover panel closes the open-sectional portions of the two side-by-side main panels forming a closed-sectional shape together with main panels; and further comprising a tensioning member which interconnects and pre-tensions the main panels that are placed side by side; and consequently, forms an assembled paneled structure with all these connective means, which is used to construct a paneled ground structures.
