Legic Prime is an artifact from the time when proprietary cryptography in RFID was considered secure enough. We will demonstrate a break for basically any aspect of Legic Prime's claimed security features. If you rely on Legic Prime's security for anything, start migrating. Legic Prime uses obscurity as one of the main defenses against misuse, with readers and cards not readily available on the free market. The system employs multiple layers of strange and obscure techniques in lieu of proper encryption and cryptographic protocols, but promises great security and management features which other systems are lacking (and lacking for good reason).
