Hopefully we'll be out of this big problem in a few months and things like this below will become important again. We can tell from Rambus' blog today that PMP is being considered for the standard - it will probably be accepted: << On the TEE side, the first draft specification is already undergoing a poll and will be going through public review next. This new standard will define a secure approach to physical memory protection (PMP) and will allow processes to be isolated from one another and make sure security applications keep their memory space private and prevent unintended leaks of information to other applications. Further topics of investigation include control flow integrity and other useful primitives for secure execution.>> We can also see on slide 17 that Rambus' CryptoManager provides PMP: |
