Fault attack resistant cryptographic systems and methods
Described herein are systems and methods that prevent against fault injection attacks. In various embodiments this is accomplished by taking advantage of the fact that an attacker cannot utilize a result that has been faulted to recover a secret.

Method and apparatus for network fraud detection and remediation through analytics
A system and method for assessing the identity fraud risk of an entity's (a user's, computer process's, or device's) behavior within a computer network and then to take appropriate action. The system uses real-time machine learning for its assessment. It records the entity's log-in behavior (conditions at log-in) and behavior once logged in to create an entity profile that helps identify behavior patterns. The system compares new entity behavior with the entity profile to determine a risk score and a confidence level for the behavior. If the risk score and confidence level indicate a credible identity fraud risk at log-in, the system can require more factors of authentication before log-in succeeds. If the system detects risky behavior after log-in, it can take remedial action such as ending the entity's session, curtailing the entity's privileges, or notifying a human administrator. |

Methods and systems for efficient virtualization of inline transparent computer networking devices
Network devices that are inserted inline into network links and process in-transit packets may significantly improve their packet-throughput performance by not assigning L3 IP addresses and L2 MAC addresses to their network interfaces and thereby process packets through a logical fast path that bypasses the slow path through the operating system kernel. When virtualizing such Bump-In-The-Wire (BITW) devices for deployment into clouds, the network interfaces must have L3 IP and L2 MAC addresses assigned to them. Thus, packets are processed through the slow path of a virtual BITW device, significantly reducing the performance. By adding new logic to the virtual BITW device and/or configuring proxies, addresses, subnets, and/or routing tables, a virtual BITW device can process packets through the fast path and potentially improve performance accordingly. For example, the virtual BITW device may be configured to enforce a virtual path (comprising the fast path) through the virtual BITW device. |
