...It utilizes the IMA logic (introduced to the Linux kernel in 2.6.30) to perform a SHA-1 measurement of all executables prior to their being placed in execution, either as a program or as a memory mapped file mapped for execution. Utilizing the QUOTE feature of the TPM, it is possible to generate an Integrity measurement Report that accurately reflects the current programs that have run or are running, and these values can be compared against a set of golden values taken from the install image of the machine. If the hash values are different, then the program has been changed, and the computer should not be trusted. ...

...This randomness is often collected from hardware sources, either pre-existing ones such as mouse movements or specially provided randomness generators. Examples for applications that depend on entropy (random numbers) would be the fortune(6) program, which gives a random quote, or the solitaire card game, or the shuffle option in a music player. Without random numbers these programs would generate the same results every time they run. High security uses for entropy would be applications that create cryptographic keys. Even after the key is eventually replaced, everything it was used to encrypt remains only as safe as the entropy used to generate the key. ...
