| Abstract(in English) | MIFARE Classic card is a contactless smart card which is one of the most popular on the market. For example, it is used for payment systems for public transport or access control system of buildings, and so on. In 2008, an attack technique for extracting the private key from a legitimate card reader was proposed by Gracia et al. However, their method needs 4096 authentications between fake MIFARE cards and a legitimate reader in the worst case. In this paper, we propose another attack for extracting the secret key of a MIFARE Classic. In our attack, the attacker uses a fake card and make an authentication session with the legitimate reader. The attacker can obtain 4096 candidates of the secret key. We further discuss how much the candidate keys can be reduced if the attacker makes multiple authentication sessions. |
