RSA and DSA are crypto algorithms. DSA offers better security with shorter
key lenght because it doesn't add as strong requirements as RSA does.
This should result in higher processing speed. The interesting part is
now that a good DSA key is harder to create than a good RSA key, for the
latter you just need a pseudo-prime. This might be what they mean with 
faster to verify.
