We analyze risks andd present the requirements of digital multisignature in electronic contract systems where several persons contract a digital document electronically. We also apply a few digital multisignature schemes that have been developed so far, to the electronic contract system and propose a new digital multisignature scheme based on the Fiat-Shamir scheme. We investigate how these schemes satisfy with the requirements and evaluate their efficiency in terms of processing speed. communication complexity, and message length Owing to the high processing speed and the high degree of satisfaction to the requirements, the proposed scheme is suitable for electronic contract systems.

As the computer-based electronic processing of financial transactions become more and more popular in financial areas, the need for more efficient and secure infrastructure has been increased. This Paper addresses the current status and Policy issues in building such infrastructure for electronic financial transactions in Korea. We examine our financial computer networks, electronic payment and clearing systems, standardization, and related laws, comparing with those in United States, Japan, and European countries and suggest policy recommendation in each area.

A glass cockpit is an aircraft cockpit that features electronic (digital) instrument displays, typically large LCD screens, rather than the traditional style of analog dials and gauges. While a traditional cockpit relies on numerous mechanical gauges to display information, a glass cockpit uses several displays driven by flight management systems, that can be adjusted to display flight information as needed. This study introduces design considerations of electronic display in KAS Part 23 airplanes.

The purpose of this study is to design a body-fat measurable electronic scale which can measure body impedance and weight. The hardware configuration of this system for the body-fat measurement includes a sinewave constant current generator, a analog switch circuit and a microprocessor with peripheral interface as well as electronic scale circuit. And the dedicated software is also designed for calculating body fat and body composition analysis from the result of the measurement.

Electronic service delivery is an integral mission that is shouldered upon e-government to carry out. And it also has become an important way of making client-centered administration work more effectively. It is quite convenient from citizens' perspective to utilize public services that are electronically transformed. This study identifies a set of electronic services currently provided by e-government and proposes policy measures for further driving e-government to develop its services in a direction of making people's life more convenient.

In this paper, we present a closed-form expression of binary sequences of longer period with ideal autocorrelation property in a trace representation, if a given binary sequence with ideal autocorrelation property is described using the trace function. We also enumerate the number of cyclically distinct binary sequences of a longer period with ideal autocorrelation property, which are extended from a given binary sequence with ideal autocorrelation property.
