I'd brush up on my security vocabulary. Even if they don't expect you to do crypto work, they'll probably want someone with some familiarity with crypto and security concepts. Here are some below, off the top of my head.
Basic terms & concepts:
Encryption / Decryption
Cipher
Hash
Public key cryptography
Symmetric key cryptography
Eliptic curve cryptography
Certificates
Certificate chaining
Authentication vs. Authorization

Algorithms & Protocols:
DES, AES, SSL, RSA, El Gamal, Blowish, Twofish, RC2, RC4, RC5
Threats:
Man-in-the-middle attack
Denial-of-service attack
Overwriting memory / Buffer overflow
If you really want to impress them, read some basic cyrpto ideas and learn how the community uses the standard set of players: Alice, Bob, Eve, and Mallory, so you can use them in your answers.
