Abstract:
(EN) Disclosed is a scheme of transmitting at least two or more transmission signals, in which at least two or more pure random noise signals are contained, through multiple paths, according to one embodiment of the present invention. To implement such a scheme, a complementary noise generator may be used in a high-speed communication method and system with enhanced security according to the present invention. Here, the complementary noise generator refers to an apparatus in which a total sum of summing altogether at least two or more generated noises becomes 0. Namely, the complementary noise generator can generate m noises, and the sum of the m noises becomes 0. By injecting a plurality of noises having such feature into different paths, a channel capacity of each channel is reduced, thereby making a single wiretapping difficult. In comparison, because a receiver receiving a plurality of transmission signals with injected noises receives all noise signals and then sums up the noise signals, the noises are offset, and it is possible to effectively receive the original signal (random key K) intended for transmitting by a transmitter.
(FR) La présente invention concerne, selon un mode de réalisation, un schéma de transmission d'au moins deux signaux de transmission, comprenant au moins deux signaux de bruit aléatoires purs à travers de multiples trajets. Pour mettre en œuvre un tel système, un générateur de bruit complémentaire peut être utilisé dans un procédé et un système de communication à haute vitesse présentant une sécurité améliorée selon la présente invention. Selon l'invention, le générateur de bruit complémentaire se rapporte à un appareil dans lequel une somme totale obtenue après l'addition d'au moins deux bruits générés est 0. En d'autres termes, le générateur de bruit complémentaire peut générer m bruits, et la somme des m bruits est 0. Grâce à l'injection d'une pluralité de bruits ayant ces caractéristiques dans des trajets différents, la capacité de canal de chaque canal est réduite, ce qui rend difficile une écoute téléphonique unique. En comparaison, du fait qu'un récepteur recevant une pluralité de signaux de transmission avec des bruits injectés reçoive tous les signaux de bruit puis additionne les signaux de bruit, les bruits sont décalés, et il est possible de recevoir efficacement le signal d'origine (clé aléatoire K) prévu pour une transmission par un émetteur.
(KO) 본 발명의 일 실시 예에 따라, 적어도 2 이상의 순수랜덤잡음 신호들이 포함된 적어도 2 이상의 송신신호들을 다중 경로를 통해 전송하는 방식을 나타낸다. 이러한 방식을 구현하기 위해 본 발명에 따른 보안이 향상된 고속통신방법 및 시스템에는 상보 잡음 발생기가 사용될 수 있다. 여기서, 상보 잡음 발생기는 발생시킨 적어도 2 이상의 잡음을 모두 합한 총 합(sum)이 0이 되는 장치를 말한다. 즉, 상보 잡음 발생기는 m개의 잡음을 발생시킬 수 있고, 해당 m개의 잡음의 합은 0이 된다. 이러한 특징을 갖는 복수의 잡음을 서로 다른 경로에 주입하여 각 채널의 채널용량이 감소되고, 그로 인해서 단일도청이 어렵게 된다. 그에 반해, 잡음이 주입된 복수의 송신신호들을 수신한 수신자는 모든 잡음 신호를 수신하고, 이들을 합하기 때문에 해당 잡음은 상쇄되고, 송신자가 전송하고자 하는 원 신호(랜덤 키K)를 효과적으로 수신할 수 있게 된다.
