For security reasons, it is desirable to check the integrity of code before execution, avoiding tampered software by an attacker. So, my question is

How to sign executable code and run only trusted software under Linux?

I have read the work of van Doom et al., Design and implementation of signed executables for Linux, and the IBM’s TLC (Trusted Linux Client) by Safford & Zohar. TLC uses TPM controller, what is nice, but the paper is from 2005 and I was unable to find current alternatives.

Do you know another options?

UPDATE: And about other OS’s? OpenSolaris? BSD family?

    The DigSig kernel module implements verification of binaries signed by a tool called bsign. However, there hasn’t been any work on it since version 2.6.21 of the Linux kernel.
