I was wondering if the linux TRESOR module (http://en.wikipedia.org/wiki/TRESOR) would protect a webserver against HeartBleed or other similar attacks.

1 Answer 1


No. TRESOR only provides a method of storing AES encryption keys in the CPU. It will not prevent an attacker from stealing certificates, user information, password, or whatever else may present in the server's RAM

  • Ok. I thought that TRESOR actually encrypted the RAM as well. Although I suppose that if HeartBleed is leaking its own memory rather than someone else's then encryption would not matter.
