Abstract: front page image
(EN)An IPSec gateway device (140) comprises: a packet reception unit (141) for receiving a packet from a terminal (110) or a server; a non-encrypted area analysis unit (142) for analyzing a non-encrypted area of the received packet to determine whether the non-encrypted area coincides with IPSec session information contained in the gateway device before receiving a packet; an encrypted area analysis unit (143) for decoding an encrypted area of a packet when the non-encrypted area does not coincide with the IPSec session information, and determining whether the decoded information coincides with an encrypted key value of the IPSec session information; an IPSec session information reconfiguration unit (144) for, when the decoded information coincides with the encrypted key value, updating information of the non-encrypted area to the IPSec session information; and a packet transmission unit (145) for transferring a packet in which the IPSec session information is updated.
(FR)Le dispositif de passerelle IPSec (140) de l’invention comprend : une unité de réception de paquets (141) servant à recevoir un paquet d’un terminal (110) ou d’un serveur ; une unité d’analyse de zone non chiffrée (142) servant à analyser une zone non chiffrée du paquet reçu pour déterminer si la zone non chiffrée coïncide avec les informations de session IPSec contenues dans le dispositif de passerelle avant la réception du paquet ; une unité d’analyse de zone chiffrée (143) servant à décoder une zone chiffrée d’un paquet lorsque la zone non chiffrée ne coïncide pas avec les informations de session IPSec, et déterminer si les informations décodées coïncident avec une valeur de clé chiffrée des informations de session IPSec ; une unité de reconfiguration d’informations de session IPSec (144) servant, lorsque les informations décodées coïncident avec la valeur de clé chiffrée, à mettre à jour les informations de la zone non chiffrée en leur donnant la valeur des informations de session IPSec ; et une unité d’émission de paquets (145) servant à transférer un paquet dans lequel les informations de session IPSec sont mises à jour.
(KO)IPSec 게이트웨이(140) 장치는 단말(110) 또는 서버로부터 패킷을 수신하는 패킷 수신부(141), 수신한 패킷의 비암호화 영역을 분석하여, 게이트웨이 장치가 패킷 수신 전에 보유한 IPSec 세션 정보와 일치하는지 여부를 판단하는 비암호화 영역 분석부(142), 비암호화 영역이 IPSec 세션 정보와 일치하지 않는 경우 패킷의 암호화 영역을 복호하고, 복호된 정보가 IPSec 세션 정보의 암호화 키값과 일치하는지 여부를 판단하는 암호화 영역 분석부(143), 복호된 정보와 암호화 키값이 일치하는 경우, 비암호화 영역의 정보를 IPSec 세션 정보에 업데이트하는 IPSec 세션 정보 재설정부(144) 및 IPSec 세션 정보가 업데이트된 패킷을 전송하는 패킷 전송부(145)를 포함한다.
