longer to encrypt and decrypt. AES provides the highest
security but will take longer than 3DES to encrypt and
decrypt.
3DES and AES are not shipped with the Router as standard due
to international restrictions on encryption. If your country permits
their use they can be downloaded from the 3Com web site at
http://www.3com.com/

perfect forward secrecy. Using perfect forward secrecy will
