NCRYPTION
CiM supports optional DES 56 encryption and decryption for additional security over the
satellite link. Each CiM supports 2 user configurable keys for encryption and 2 user
configurable keys for decryption. Each route can be assigned to be encrypted by Key 1 or
Key 2 or Random (i.e. CiM selects Key 1 or Key 2 randomly on a per IP datagram basis)
or transmitted in Clear (i.e. no encryption).
