摘要： A system and method includes a processing unit connected with a memory, the processing unit configured to access data from the memory. A memory transaction unit is added between the processing unit and the memory. The memory transaction unit is configured to perform dummy read- and write- operations at random memory locations at random times and/or insert random delays before real accesses by the processing unit from the memory.

摘要： A network intrusion detection system and method is configured to receive off-line network traffic. The off-line network traffic with a predefined format, PCAP file, is capable of indicating existence of a plurality of covert channels associated with a corresponding plurality of covert channel signatures. Each covert channel comprises a tool that communicates messages by deviating from a standard protocol to avoid detection. A plurality of covert channel processors are configured to analyze off-line network traffic. The analysis determines whether the off-line network traffic deviates from the standard protocol based on one or more covert channel signatures. The covert channels are employed in at least one standard layer of the standard protocol stack and the off-line network data traffic comprises at least one standard protocol stack having multiple standard layers.

摘要： The methods and systems described herein provide for securing sensitive information using a hypervisor-trusted client, in a computing device executing a hypervisor hosting a control virtual machine and a non-trusted virtual machine. A user of a non-trusted virtual machine executed by a processor of a computing device requests to establish a connection to a remote computing device. A control virtual machine executed by the processor of the computing device launches a client agent, responsive to the request. A graphics manager executed by the processor of the computing device assigns a secure section of a memory of a graphics processing unit of the computing device to the client agent. The graphics manager renders graphical data generated by the client agent to the secure section of the graphics processing unit memory.

摘要： Embodiments of the invention provide a secret value estimation device (13) for determining an estimate of at least one secret value used by at least one cryptographic mechanism (11) implemented in a cryptographic system (11) from a statistical distribution of a set of multivariate leakage traces (12) determined by a leakage traces statistical distribution unit (14). Each leakage trace being a vector comprises a plurality of random values, the number of said random values being an integer number superior or equal to 1, the statistical distribution being a function of parametric linear combinations of a set of leakage model basis vectors representing a multivariate leakage model, the number of basis vectors being an integer number superior or equal to 1, and the linear combinations being defined by a matrix of real values.
