How to encrypt the loading external swf into another on the web

Hello to all,
I’m using one basic file to load many 1000’s of swf on this single
swf according to the user interaction. the problem is i can modify
this single basic file but not those 1000 swf files.
Now i want to protect them from downloading from the net or if someHow
downloaded the to encrypt the actionscript coding.
when i encrypt the basic file and then load other files into it i want
those also to be encrypted
Suggest me…
Thanx.

Regards,
Hems
