Title (EN) ENCRYPTION DEVICE AND METHOD FOR DEFENDING A PHYSICAL ATTACK
(FR) DISPOSITIF DE CHIFFREMENT ET PROCÉDÉ DE DÉFENSE CONTRE UNE ATTAQUE PHYSIQUE
(KO) 물리적 공격을 방어하는 암호화 장치 및 암호화 방법
Abstract: front page image
(EN)Provided are a security device and a method for operating same. The security device may conceal an encryption key used for an encryption algorithm in an encryption module in correspondence to security attacks such as reading information on where the encryption key is stored in a memory by disassembling an IC chip, or extracting said information through microprobing. The encryption key may be included as a physical encryption key module in an encryption module, and a certain storage medium for storing the encryption key may be included in the encryption module. Accordingly, the encryption key is not transmitted via a bus in a security device for encryption.
(FR)L'invention concerne un dispositif de sécurité et un procédé pour mettre en oeuvre ce dispositif. Le dispositif de sécurité peut dissimuler une clé de chiffrement utilisée pour un algorithme de chiffrement dans un module de chiffrement en correspondance avec des attaques de sécurité telles que la lecture d'informations concernant l'emplacement où la clé de chiffrement est mémorisée dans une mémoire en désassemblant une puce de circuit intégré, ou l'extraction desdites informations par microsondage. La clé de chiffrement peut être incluse en tant que module de clé de chiffrement physique dans un module de chiffrement, et un certain support de mémorisation pour mémoriser la clé de chiffrement peut être inclus dans le module de chiffrement. Par conséquent, la clé de chiffrement n'est pas transmise par l'intermédiaire d'un bus dans un dispositif de sécurité pour un chiffrement.
(KO)보안 장치 및 보안 장치의 동작 방법이 제공된다. 보안 장치는 물리적 공격, 이를테면 IC 칩을 분해하여 메모리내의 암호키의 저장부분의 정보를 읽어내거나 마이크로 프로빙(Micro-probing)을 통하여 추출해내는 공격과 같은 보안상 공격에 대응하여, 암호화 알고리즘에 사용되는 암호키를 암호화 모듈 내부에 은닉하여 가지고 있을 수 있다. 암호키는 암호화 모듈 내부에 물리적인 암호키 모듈로서 포함될 수 있으며, 또한 암호키를 저장하고 있는 어떤 저장 매체가 상기 암호화 모듈 내에 포함되어 있을 수 있다. 따라서, 암호화를 위해 보안 장치 내의 버스(bus) 등을 통해 암호키가 전송되지 않는다.
