Santa has caught up with the information age and does not trust
|
|
|
|
|
clear-text commands anymore.
|
|
|
|
|
He has decided that all communications
|
|
|
|
|
have to be encrypted to prevent an unfriendly take-over of his team.
|
|
|
|
|
Santa chooses a simple, secure, and toolless encryption scheme.
|
|
|
|
|
However, his team's memory capacity is limited and so he can only use
|
|
|
|
|
their names (Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Donder and
|
|
|
|
|
Blitzen) as keys.
