Greetings, Is there any way to protect a programs memory space from all users, even root? I am developing an encryption program that has to run as a daemon. Upon start-up the program would prompt for the key, then slip into daemon land. If the server is compromised (root access is gained) can I prevent the cracker from reading the program's memory and gaining access to the key data? As long as I can keep the key secure, the data should be safe (I'm using IDEA in chain-block mode). I'm currently writing the program in C. If this is not possible (protecting the key), then can someone shed some light on how I can protect sensitive data on an on-line machine? I know, I know, but this data "has" to be on-line for processing that happens all day long.
