I thought that wasn't possible since DDR3 or 4?
- ATsch 6y agoSmaller capacitors will keep their charge less long, which makes this more difficult, but I understand that there are no fundamental mitigations.
- Avamander 6y agoThere's (T)SME.
- jleahy 6y agoThe fundamental mitigation is full memory encryption using a randomly generated key that changes each time the CPU boots. That exists for some CPUs.
- ATsch 6y agoWell, that's not part of the ddr3 or ddr4 spec :)
- Spivak 6y agoWhere do you store the key?
- danielheath 6y agoCPU registers - much harder to pull off and reattach elsewhere.
