RAMus: Cryptographically Secure Memory

As a research team at Edinburgh Napier, we spend quite a bit of time examining memory, and in discovering encryption artefacts. This includes discovering encryption keys and passwords. For some reason, those who create secure applications often forget that memory can be examined, and often leave encrypted forms in a way they can be discovered. And so keys that should take trillions of years to crack by brute force can be discovered in a relatively short time period.

Attacks have included the cold boot attack:

And here is our research where we can discover a 128-bit AES key within 30 minutes:

So, now a new research paper aims to overcome these problems [here][1]:

You will notice it includes Vincent Rijmen as an author, and who was one of the creators of Rijndael — aka AES…
