- I'm currently experimenting with a system which encrypts frames at the IP
- level, which allows authentication and confidentiality. When an IP packet is
- received, the system checks if it's encrypted (by the "protocol" field in the
- header), and if so, the packet is decrypted and then relayed to TCP, UDP etc.
- If TCP, UDP want to send a packet, it's first encrypted and then relayed to IP.
-
- It is easy enough to implement this in my own TCP/IP implementation, and should
- be possible with BSD by modifying the kernel source. However, my question is:
- is it possible with BSD or even System V systems to implement protocols outside
- of the kernel? I.e., create a binary which has the functionality mentioned above
- but does not require you to change your kernel?
-
- Any suggestions are welcome
