In this paper, memory reduction method using the Sub-PFP is proposed. That is, two-dimensional PFPs in conventional N-LUT method can be converted by one-dimensional Sub-PFPs using trigonometric relations. Some experiments with a test 3-D object are carried out and the reduction ratio of LUT is analyzed.

White box cryptography is the new technique against attacks on white box attack environments. In white box attack model, the attacker is even stronger than in black box attack model, and the attacker can monitor all intermediate values. Therefore, safety algorithms are needed against all operation steps being exposure. Chow introduced secure white box cryptography with AES DES implementations against white box attack model [1,2]. However, slower performance by operating too many look up tables is a problem of practical use of white box cryptography. Also key updating on dynamic situations of white box cryptography is much harder than key updating of black box cryptography. Thus, this paper suggests using a specific mode of operation to improve speed of white box implementations, and show concrete examples of enhancement of performance. Also, it suggests a technique of key updating with dynamic and static tables in practically.

In this paper, We present more accurate access delay analysis through the consideration of piggyback request. In our analysis, we derived a formula for access delay introducing a self-similar traffic model to prove the effect of the piggyback request. We also show that the piggyback request can greatly affect the access delay under high traffic conditions.

Desktop virtualization allows IT developments to reduce management and support costs, along with capital expenses for desktop hardware. Therefore, a user uses virtualization services using management tools, but they are not compatible with each other. As a result, t he O VF i s used as t he standard for the virtual machine image in order to provide virtualization solution for companies. Therefore, in this paper, we suggest the management software can generalize a management API and a user interface used in the management tool and can be used even in the virtualization solutions of any companies.

The Mint-Route routing protocol was proposed to enhance reliability by choosing adjacent link with the smallest number of lost packets as next hop in wireless sensor networks. However, since packets are transmitted over unstable wireless link, physical distance between nodes can mostly affect the reliability. So, long path with many hops is usually established between source and destination while considering current metrics. To solve this problem, we develop a revised Mint-Route protocol by considering the received packet as well as distance together while deciding parent node toward the sink. Simulations and their analysis are followed to validate the suitability of reduced end-to-end delay and enhanced reliability.

Communications in underwater wireless sensor networks have a lot of limitations as compared to those in terrestrial sensor networks. In wireless sensor networks, a routing protocol finds a path between the source and sink nodes according to a routing metric. The hop count is the most widely used routing metric, however, it cannot reflect the quality of a link. It is expected that a link quality aware metric such as ETX can contribute to improving the performance, especially in underwater sensor networks (UWSNs). However, the direct adoption of ETX in UWSNs may not provide expected performance. In this paper, we investigate the effect of ETX measurement on the performance in UWSNs through NS-2 simulations.

In this paper, we build a framework for maximizing the utilization of solar-based harvesting energy in sensor networks. For this goal, we analyze the required power at each relay node and give the queueing framework for the power management. In the simulation, our proposed algorithm shows a superior performance than conventional ones in terms of the PRR (Packet Reception Rate) for a day according to the recharging efficiency.
