Abstract: Provided are exemplary embodiments including a method for creating and using a personal encounter history using a communication device. The method involves the communication device receiving the transmission of a pseudo identifier from a proximal communication device where the pseudo identifier is associated with the user of the proximal communication device. Once received, the method continues with the wireless communication device requesting and receiving the actual identification of the user of the proximal communication device that is correlated with the pseudo identifier. The communication device includes a transceiver capable of communicating wirelessly with a mobile telecommunications network, a memory device and a processor. To ensure privacy, the processor is capable of receiving a pseudo identifier from a proximate communication device and then requesting an actual identification correlated with the pseudo identifier of the proximate communication device.

Abstract: The disclosed computer-implemented method for determining reputations of digital certificate signers may include (i) identifying a group of endpoint devices that have accessed files to which a digital certificate signer has attached digital certificates that assert the files are legitimate, (ii) determining, for each endpoint device, whether a security state of the endpoint device is compromised or uncompromised based on a security analysis of computing events detected on the endpoint device, (iii) classifying the digital certificate signer as potentially malicious by determining that the files were accessed more frequently by endpoint devices with compromised security states than by endpoint devices with uncompromised security states, and (iv) protecting a security state of an additional endpoint device by preventing the additional endpoint device from accessing a file with a digital certificate signed by the digital certificate signer.

Abstract: In an example embodiment, a method for protecting against confidential data-based inference attacks in a computer system is provided. A first confidential data value is received.

Abstract: A system and method for detecting replay attacks on secure data are disclosed. A system on a chip (SOC) includes a security processor. Blocks of data corresponding to sensitive information are stored in off-chip memory. The security processor uses an integrity data structure, such as an integrity tree, for the blocks. The intermediate nodes of the integrity tree use nonces which have been generated independent of any value within a corresponding block. By using only the nonces to generate tags in the root at the top layer stored in on-chip memory and the nodes of the intermediate layers stored in off-chip memory, an amount of storage used is reduced for supporting the integrity tree. When the security processor detects events which create access requests for one or more blocks, the security processor uses the integrity tree to verify a replay attack has not occurred and corrupted data.

Abstract: A proxy server receives, from multiple visitors of multiple client devices, a plurality of requests for actions to be performed on identified network resources belonging to a plurality of origin servers. At least some of the origin servers belong to different domains and are owned by different entities. The proxy server and the origin servers are also owned by different entities. The proxy server analyzes each request it receives to determine whether that request poses a threat and whether the visitor belonging to the request poses a threat. The proxy server blocks those requests from visitors that pose a threat or in which the request itself poses a threat. The proxy server transmits the requests that are not a threat and is from a visitor that is not a threat to the appropriate origin server.

Abstract: A system and method for analyzing cyber-security risk inter-dependencies in a control system having networked devices. The system includes a central server that has a processor and a memory device in communication with the processor. The memory device stores inter-device dependencies and quantified individual risks for each of the networked devices. The memory device also stores a dynamic quantification of risk (DQR) program.
