Several approaches to protect data and code, and ensure execution in a secure environment without getting infected from malwares, such as isolation, sandboxing, trust-based execution, application oriented access control have been proposed. In recent times, hardware-based solutions like ARM TrustZone and Intel SGX Enclave have been introduced to protect code and data from being infected or modified...
We present a secure design for a map-reduce framework that guarantees preservation of privacy of the original data. We use Hadoop as a typical environment for illustration. That is, in spite of the data divisions/replications for the computations, the privacy of the original data remains invariant. Specifically, we use the novel information flow model called RWFM model that assures that in spite of...
This paper presents a three-dimensional (3-D) simulation of a triode-type magnetron injection gun (MIG) for a 42-GHz 200-kW gyrotron with a transverse-to-axial velocity ratio of the electron beam at 1.22 and a maximum transverse-velocity spread of 3.2%. The operating mode of the gyrotron is TE_03, and it is operated in the fundamental harmonic. The MIG has been designed by using some tradeoff equations...
