A security system is disclosed. The security system includes a secure zone, user access to which is restricted, a first gateway encrypted using a first encryption algorithm, and a second gateway encrypted using a second encryption algorithm. The first gateway is configured to restrict access to the second gateway, and the second gateway is accessible via the first gateway with a first key. The second gateway is configured to restrict access to the secure zone, and the secure zone is accessible via the second gateway with a second key. The first encryption algorithm is different from the second encryption algorithm. |
