【Abstract】 The shortwave communications is indispensability required in certain field and situation, and its security has always been a widespread concern. Without the requirement for extra hardware￡’’this paper designs and implements a security system of shortwave transmission, which can supply encryption of data, digital sign and identification service. Moreover, the authors discuss the issue of key management.更多还原
