The Megamos Crypto transponder is used in one of the most widely deployed electronic vehicle immobilizers. It is used among others in most Audi, Fiat, Honda, Volkswagen and Volvo cars. Such an immobilizer is an anti-theft device which prevents the engine of the vehicle from starting when the corresponding transponder is not present. This transponder is a passive RFID tag which is embedded in the key of the vehicle. In this paper, the authors have reverse-engineered all proprietary security mechanisms of the transponder, including the cipher and the authentication protocol which we publish here in full detail. This article reveals several weaknesses in the design of the cipher, the authentication protocol and also in their implementation.

RSA BSAFE SSL-J versions prior to 6.2.4 contain a heap inspection vulnerability that could allow an attacker with physical access to the system to recover sensitive key material. RSA BSAFE SSL-J versions prior to 6.2.4 contain a covert timing channel vulnerability during RSA decryption, also known as a Bleichenbacher attack on RSA decryption. A remote attacker may be able to recover a RSA key. RSA BSAFE Crypto-J versions prior to 6.2.4 and RSA BSAFE SSL-J versions prior to 6.2.4 contain a covert timing channel vulnerability during PKCS #1 unpadding operations, also known as a Bleichenbacher attack. A remote attacker may be able to recover a RSA key.

BSides Brussels is a security conference in Brussels, Belgium, with talks, workshops and villages. The goal is to strengthen the exchange of knowledge, cooperation, communication, and integration between the different actors active in the IT security industry. We are pleased to announce that the first edition of BSides Brussels will be held on May 28th, 2020.
