Abstract

This paper proposes a simple encryption technology for space-time block coding algorithm. Space-time block coding algorithm uses two antennas in transmitting data which consists of original data and transformed data for the purpose of combining in the receiver. This kind of two transmission antenna data could be exchanged and transmitted on each other's antenna individually, which can be used as a simple encryption algorithm. Encryption timing control informations should be shared between transmitter and receiver beforehand. It is shown that the proposed architecture can give performance enhancement compared with no encryption cases.

본 논문은 시공간 블록 코딩 알고리즘을 위한 간단한 암호화 기법을 제안한다. 시공간 블록 코딩 알고리즘은 데이터를 전송하는데 두 개의 안테나를 사용하며, 전송 데이터는 원래의 데이터와 수신기에서 결합하기 위하여 변형된 데이터로 구성된다. 이러한 종류의 두 개의 송신 안테나 데이터는 각각 상대방의 안테나와 교환되어 전송될 수 있으며, 이러한 방법은 간단한 암호화 알고리즘으로 사용될 수 있다. 암호화 시간 제어 정보는 송신기와 수신기 사이에서 미리 공유되어야 한다. 제안된 구조는 암호화 알고리즘이 없는 경우와 비교하여 성능이 향상됨을 제시하였다.
