Abstract:
(EN) A public physical unclonable function (PPUF)-based data transmission method using an adaptive secret key comprises the steps in which: a transmitter determines a first challenge set including multiple first challenge values, and a response set including multiple responses by repeating a process of determining the first challenge values by using delay characteristics of any PPUF, and determining the response values which are outputted at a reference time after the first challenge values are inputted; the transmitter transmits information including the reference time and the response set, and transmits encrypted data using a secret key generated using the multiple first challenge values; a receiver receives the information, and determines a second challenge set including multiple second challenge values by repeating a process of determining the particular second challenge values for, for each and every response value included in the response set, outputting each response value at the reference time from the time point when the challenge values are inputted on a PPUF circuit having the delay characteristics; and the receiver decrypts the encrypted data using a secret key generated using the multiple second challenge values.
(FR) L'invention concerne un procédé de transmission de données basé sur une fonction non clonable physique publique (PPUF) utilisant une clé secrète adaptative et qui comprend les étapes suivantes : un émetteur détermine un premier ensemble de défis comprenant de multiples premières valeurs de défi, et un ensemble de réponses comprenant de multiples réponses en répétant un processus de détermination des premières valeurs de défi à l'aide de caractéristiques de retard de n'importe quelle PPUF, et de détermination des valeurs de réponse qui sont délivrées à un instant de référence après que les premières valeurs de défi sont entrées ; l'émetteur transmet des informations comprenant le temps de référence et l'ensemble de réponses, et transmet des données chiffrées à l'aide d'une clé secrète générée au moyen des multiples premières valeurs de défi ; un récepteur reçoit les informations, et détermine un second ensemble de défis comprenant de multiples secondes valeurs de défi en répétant un processus de détermination des secondes valeurs de défi particulières afin de délivrer, pour chaque valeur de réponse incluse dans l'ensemble de réponses, chaque valeur de réponse au moment de référence à partir du point temporel où les valeurs de défi sont entrées sur un circuit PPUF ayant les caractéristiques de retard ; et le récepteur déchiffre les données chiffrées à l'aide d'une clé secrète générée à l'aide des multiples secondes valeurs de défi.
(KO) PPUF에 기반한 적응적 비밀키를 사용하는 데이터 전송 방법은 송신기가 어느 PPUF(Public Physically Unclonable Function)의 지연 특성을 이용하여 제1 챌린지값 및 상기 제1 챌린지값이 입력된 후 기준 시간에 출력되는 리스폰스값을 결정하는 과정을 반복하여 복수의 제1 챌린지값을 포함하는 제1 챌린지 세트 및 복수의 리스폰스를 포함하는 리스폰스 세트를 결정하는 단계, 상기 송신기가 상기 기준 시간 및 상기 리스폰스 세트를 포함하는 정보를 전송하고, 상기 복수의 제1 챌린지값을 이용하여 생성된 비밀키를 이용하여 암호화한 데이터를 전송하는 단계, 수신기가 상기 정보를 수신하고, 상기 리스폰스 세트에 포함되는 모든 리스폰스값 각각에 대해 상기 지연 특성을 갖는 PPUF 회로에서 챌린지값 입력 시점부터 상기 기준 시간에 상기 각 리스폰스값을 출력하는 특정한 제2 챌린지값을 결정하는 과정을 반복하여 복수의 제2 챌린지값을 포함하는 제2 챌린지 세트를 결정하는 단계 및 상기 수신기가 상기 복수의 제2 챌린지값을 이용하여 생성된 비밀키를 이용하여 상기 암호화한 데이터를 복호하는 단계를 포함한다.
