  • The electrooptical characteristics of OMI (optical mode interference) cell were investigated as the application for LC shutters. The optical responses under dynamic driving were simulated by solving the Ericksen-Leslie hydrodynamic equations numerically. The prototypes were made accordingly for verification. The experimental data show good coincidence with the simulation results.

  • 본 논문에서는 Zheng이 제시한 비밀키 암호시스템인 SPEED를 개선한 암호시스템을 제안한다. 제안된 암호시스템에서는 암호화에 사용되는 부울 함수를 키에 따라 가변적으로 함수 풀(function pool)로부터 선택함으로써 함수 선택에 대한 약간의 오버헤드만으로 선형 공격(linear cryptanalysis) 및 차분 공격(differential cryptanalysis)등 알려진 공격에 대해 향상된 저항성을 가지도록하였다.
