Zusammenfassung: | According to an embodiment of the present invention, an end-to-end cryptographic communication method between devices of a telematics system exchanges encrypted data by omitting a key exchange procedure for cryptographic communication and transferring a shared secret value capable of generating an encryption key capable of decrypting an encryption text together with the encryption text. At this time, cryptographic communication is performed using a different shared secret value for each message.
발명의 일 양상에 따른 텔레매틱스(Telematics) 시스템의 장치간 End to End 암호화 통신 방법은 암호화 통신을 위한 키 교환 절차를 생략하고 암호문과 함께 해당 암호문을 복호화할 수 있는 암호화 키를 생성할 수 있는 공유 비밀값을 전달하는 방식으로 암호화된 데이터를 교환한다. 이때 모든 각각의 메시지마다 다른 공유 비밀값을 사용하여 암호화 통신을 수행한다. |
