In this paper, we present a novel failed flow dispersion estimation technique, called multi-window state map (MWSM), which requires a small amount of memory and a constant number of memory accesses for implementing the multi-resolution concept (e.g., MRDS). We then extended the proposed MWSM scheme into a complete port scan detector. The simulation...

Repackaging is the one of the most common techniques used by Android malwares. Recently, as one approach to prevent the repackaged malwares, it is considered to use the trust agency that guarantees the app developer. However, these approaches have no or limited secure channel to deploy the guaranteed apps. No secure channel poses another security i...

Although port scan detection techniques have been widely adopted by the modern network based security systems, the effectiveness of these techniques can significantly be limited since the detection performance heavily relies on the statically determined detection threshold. To tackle the problem, a multi-resolution approach called MRDS, maintaining...

. Application developers face many challenges when developing applications for embedded systems. A major challenge is meeting the conflicting constraints of speed, code density, and power consumption. Traditional optimizing compiler technology is usually of little help in meeting such constraints. To meet speed, power, and size constraints applicat...

It has long been known that a single ordering of optimization phases will not produce the best code for every application. This phase ordering problem can be more severe when generating code for embedded systems due to the need to meet conflicting constraints on time, code size, and power consumption. Given that many embedded application developers...
