Abstract:
System and method for virtualization of computing elements. A hypervisor provides virtualization of one or more peripherals for one or more computing elements. The hypervisor may further allow separate instances of an operating system to be suspended on one computing element to allow another application to be processed by replacing the state information of the computing element. The suspended instance may be resumed on the same or a different computing element.

Abstract:
A system and method for improving performance while transferring encrypted data in an input/output (I/O) operation are provided. The method includes receiving a block of data. The method also includes dividing the block of data into a plurality of sub-blocks of data. The method further includes performing a first operation on a first sub-block. The method also includes performing a second operation on a second sub-block at substantially the same time as performing the first operation on the first sub-block. The method still further includes reassembling the plurality of sub-blocks into the block of data.

Abstract:
Systems and methods are described for allowing the execution of authorized computer program code and for protecting computer systems and networks from unauthorized code execution. In one embodiment, a multi-level proactive whitelist approach is employed to secure a computer system by allowing only the execution of authorized computer program code thereby protecting the computer system against the execution of malicious code such as viruses, Trojan horses, spy-ware, and/or the like. Various embodiments use a kernel-level driver, which intercepts or “hooks” certain system Application Programming Interface (API) calls in order to monitor the creation of processes prior to code execution. The kernel-level driver may also intercept and monitor the loading of code modules by running processes, and the passing of non-executable code modules, such as script files, to approved or running code modules via command line options, for example. Once intercepted, a multi-level whitelist approach may be used to authorize the code execution.
