Abstract: Various embodiments of the present disclosure provide a scan-based architecture for register-transfer-level (RTL) or gate-level designs that improves the security of scan chain-based design-for-testability (DFT) structures. In various embodiments, the scan-based architecture includes invisible scan chains that are hidden in such a way that an attacker cannot easily identify or locate the invisible scan chains for exploitation and revealing internal secure information of the design. The invisible scan chains are dynamically configurable into a scan chain with select flip-flops, such that scan paths of the invisible scan chains may be different between different designs, chips, or testing operations. Various embodiments further employ key-based obfuscation by combining a scan control finite state machine with existing state machines within a design, which improves design security against unauthorized use and increases confidentiality.

Abstract: A set of user interface tools is described facilitating asynchronous adjudication of one or more regions-of-interest in a medical image by a group of two or more graders, each of which has access to the set of tools in a workstation environment. The set of tools include (1) a feature for enabling the graders to assess the medical image and manually delineate one or more specific regions-of-interest (ROI) in the medical image, (2) a feature for assessing the ROI(s) delineated by other graders, including display of the ROI delineated by other graders; (3) dialog features for explaining and discussing the assessments, including a text feature for discussing the assessments. The dialog features and the ROIs delineated by all the graders are visible to all the graders on the workstation display as they collectively adjudicate the medical image in a round-robin manner. The set of tools further include (4) a feature for manually verifying grader agreement with the other graders' assessments.

Abstract: A method and system for evaluating software tools that detect malicious hardware modifications is provided. In one embodiment, among others, a system comprises a computing device and an application. The application causes the computing device to at least receive hardware description language code that represents a circuit design and calculate a signal probability for one or more nodes in the circuit design. The application also causes the computing device to identify one or more rare nodes in the circuit design and generate a Trojan sample population. The application further causes the computing device to generate a feasible Trojan population and generate a Trojan test instance based at least in part on a random selection from the Trojan feasible population. Additionally, the application causes the computing device to generate modified hardware description code from the Trojan test instance.

Abstract: A joint compression and encryption system is configured to retrieve, from a local memory or image capture device, an image file including a first plurality of segments. The system is further configured to identify, for one or more segment of the first plurality of segments, a matching segment in a local segmentation repository. The system is further configured to compress remaining segments of the first plurality of segments for which no matching segment was identified into a compressed remaining segment set. The system is further configured to transmit, via an unsecure communication channel and to a second computing entity, the identifications of the matching segments, and the compressed remaining segment set. The system is further configured to, prior to retrieving the image file, perform a handshake or calibration process. The system is further configured to encrypt the matching segments using a key into an encrypted segment set and transmit the key to the second computing entity.

Abstract: A personal communications internetwork provides a personal communications internetwork providing a network subscriber with the ability to remotely control the receipt and delivery of wireless and wireline electronic text messages. The network operates as an interface between wireless and wireline networks. The subscriber's message receipt and delivery options are maintained in a database which the subscriber may access by wireless or wireline communications to update the options programmed in the database.

Abstract: A person communications internetworking provides a network subscriber with the ability to remotely control the receipt and delivery of wireless and wireline voice and text messages. The network operates as an interfaces between various wireless and wireline networks, and also performs media translation, where necessary. The subscriber's message receipt and delivery options are maintained in a database which the subscriber may access by wireless or wireline communications to update the options programmed in the database. The subscriber may be provided with CallCommand service which provides real-time control of voice calls while using a wireless data terminal or PDA.

Abstract: An interface between a protected computer or computer network and the World Wide Web (WWW). The interface comprises a split proxy system that encapsulates TCP/IP transmissions into a script transmission, which is not subject to problems in high latency systems, thereby greatly improving WWW access, via a wireless modem or other low-bandwidth communications network. The split proxy interface also provides compression, encryption and filtering capabilities and allows receipt of unsolicited transmissions from the service provider for such purposes as automatically updating or configuring WWW access software.

Abstract: Liquid antacid compositions for neutralizing stomach acid in humans and other animals comprising: an alkaline earth carbonate salt; and alkali metal phosphate salt; an alkali metal bicarbonate salt; and other excipients.

Abstract: This invention is an improved mild personal cleansing syndet bar comprising: long chain synthetic surfactant having essentially saturated C.sub.15 -C.sub.22, preferably C.sub.16 -C.sub.18, alkyl or acyl chains, more preferably cetearyl sulfate; a high lathering, mild synthetic surfactant, preferably C.sub.12 -C.sub.14 acyl isethionate; soap; fatty acids; sodium isethionate; paraffin wax, preferably a high melting point paraffin wax, and optionally, but preferably, cationic polymer. The bar has improved processability, good smear and in-use properties as well as improved mildness and rinsability without meaningful lather negatives.
