questions about ipsec-tools-0.4 and linux kernel 2.6

I am a student of engineering in  first university of 
Rome (“La Sapienza”) and I’m working to my degree
thesis whose title is: 
“End-to-end real-time applications performance
measurements on VPN  network (both terrestrial  and 
satellite),  blocks encryption algorithms vs stream
cipher ones.”

Since I have to use a Linux based test bed, I must
integrate the stream cipher algorithms (like Scream
and Seal cipher algorithm)in the Linux ipsec
implementation; at aim I wonder whether you can help
me by providing the following information:
Architectural description  of the ipsec Linux
implementation (both tools and kernel modules) 
the files of kernel version 2.6 and ipsec-tools-0.4
that I should modify in order to add chiper stream
algorithm
if someone else is facing the same topic.

Thanks for your help
Best regards
