Symmetric cryptography has two advantages in this application: 1. it
requires fewer resources to implement and 2. there aren't any data
dependent vulnerabilities like there are with public key algorithms. It's
like encrypted e-mail: you use the symmetric key for the data and the
public key to encrypt the symmetric key. Since the symmetric key is secret
random data, it's less susceptable to attack.
